Detailed Description

In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

Fig. 1 is a flow chart of a network attached storage detection method according to a first embodiment of the present disclosure, as shown in fig. 1, the network attached storage detection method includes:

step S101, NAS mounting information on a current server is obtained, and NAS configuration information written in a file system table is queried.

In this embodiment, the internet protocol (IP, internet Protocol) address of the current server is input first, and then the current server is entered, then NAS mount information on the current server is acquired based on a mount command, and NAS configuration information written in a file system table (fstab, file system table) is queried based on a cat command. The NAS mounting information is NAS information actually mounted on the current server, and the NAS configuration information is configuration information which is written in fstab in advance and is used for realizing NAS mounting. Specifically, NAS mount information on the current server may be obtained based on the "mount|grep nfs" command, and NAS configuration information written in the file system table may be queried based on the "cat/etc/fstab|grep nfs" command.

Step S102, detecting whether the NAS mounting information is in an available state or not, and obtaining a detection result.

In this embodiment, it is further required to detect whether NAS mounting information actually mounted on the current server is in an available state, that is, detect whether NAS corresponding to NAS mounting information has a read-write function, if both the read-write functions are normal, NAS mounting information is in an available state, otherwise NAS mounting information is in an unavailable state. Specifically, whether NAS mount information is in an available state may be detected based on read-write commands such as ls command, cd command, and rm command.

Step S103, based on the NAS mounting information, the NAS configuration information and the detection result, determining the NAS detection type corresponding to each piece of NAS information in the current server.

In this embodiment, when classifying NAS information, each piece of NAS information in the current server needs to be classified, specifically, not one piece of NAS information is corresponding to each NAS, if one NAS is mounted on two NAS mounting paths, two pieces of NAS information can be obtained based on the NAS and the two NAS mounting paths corresponding to the NAS, so when classifying NAS information, both pieces of NAS information need to be classified. Specifically, the NAS information includes NAS configuration information and NAS mount information, and for one piece of NAS information, it may be mounted on the current server and written into fstab at the same time, that is, it may be NAS configuration information and NAS mount information at the same time; it is also possible to mount on the current server only without writing in fstab, or write in fstab only without mounting on the current server, i.e. it may be NAS configuration information or NAS mount information only, so that the NAS detection type corresponding to NAS information may be determined based on whether NAS information is in an available state and the dependency relationship between NAS information and NAS mount information and NAS configuration information.

In an embodiment, the NAS detection types may include a first type, a second type, and a third type, and in a case where NAS information is mounted on a current server and the NAS information is in an available state, it may be determined that the NAS detection type corresponding to the NAS information is the first type; under the condition that NAS information is mounted on a current server and the NAS information is in an unavailable state, determining that a NAS detection type corresponding to the NAS information is a second type; and under the condition that the NAS information is not mounted on the current server but is written into the fstab, determining that the NAS detection type corresponding to the NAS information is a third type.

Step S104, if the NAS detection type is the first type, the NAS information is subjected to baseline detection based on the first detection strategy, and NAS detection results corresponding to the NAS information are obtained.

In this embodiment, if the NAS detection type is the first type, and at this time, the NAS information is mounted on the current server and in an available state, then only baseline detection is required for the NAS information based on the first detection policy, that is, availability advanced inspection is performed for the NAS information, so as to obtain a NAS detection result corresponding to the NAS information.

Step S105, if the NAS detection type is the second type or the third type, the NAS information is checked based on the second detection strategy, and a check result corresponding to the NAS information is obtained.

In this embodiment, if the NAS detection type is the second type or the third type, and the NAS information is mounted on the current server but is in an unavailable state, or is not mounted on the current server but is written in fstab, the NAS information is checked based on the second detection policy, and then the NAS information is checked for an unavailable reason, so as to obtain a check result.

Step S106, determining NAS detection results corresponding to the NAS information based on the investigation results corresponding to the NAS information and the NAS detection types.

In this embodiment, after the NAS information is inspected and detected based on the second detection policy, NAS detection results may be different if NAS detection types are different for the same inspection result, and therefore, it is also necessary to specifically determine the NAS detection result corresponding to the NAS information based on the inspection result and the NAS detection type corresponding to the NAS information.

For the first embodiment of the present disclosure, NAS mount information on a current server and NAS configuration information written in a file system table are first obtained, and whether the NAS mount information is in an available state is detected, so as to obtain a detection result, then based on the NAS mount information, the NAS configuration information and the detection result, a NAS detection type corresponding to each piece of NAS information in the current server is determined, and finally based on a detection policy corresponding to each detection type, NAS information is detected, so as to obtain a NAS detection result corresponding to the NAS information. Therefore, the present disclosure provides an automatic NAS detection method, which can simplify the NAS operation and maintenance process, improve NAS detection efficiency, and save a great amount of time and manpower.

Fig. 2 is a flowchart illustrating a network attached storage detection method according to a second embodiment of the present disclosure, as shown in fig. 2, in step S102, detecting whether NAS mount information is in a usable state, including:

step S201, all NAS mounting paths on the current server are obtained based on the df command, whether the response time of the df command is smaller than a first preset threshold value or not is detected, and whether the NAS mounting paths are matched with NAS mounting information or not is detected, so that a first detection result is obtained.

In this embodiment, all NAS mounting paths on the current server, NAS corresponding to the NAS mounting paths, and disk occupation conditions of the NAS mounting paths may be obtained based on the "df-ah|grep" command, that is, all NAS information mounted on the current server may be obtained based on the command, whether the df command can output all NAS mounting paths within a first preset threshold time may be detected, and whether the output NAS mounting paths are the same as the mounting paths displayed in the NAS mounting information, so as to obtain a first detection result, where the first detection result may display a reading capability of the NAS mounting information. Specifically, the first preset threshold may be 5s.

Step S202, based on the ls command, obtaining all the working contents under the NAS mounting path, and detecting whether the response time of the ls command is smaller than a second preset threshold value, so as to obtain a second detection result.

In this embodiment, all the working contents under each NAS mount path on the current server may be obtained based on the "ls/NAS mount path" command, and whether the ls command can output all the working contents within the time of the second preset threshold is detected, so as to obtain a second detection result, where the second detection result may display the reading capability of the NAS mount information and the number of files under the corresponding mount path. Specifically, the second preset threshold may be 20s.

Step S203, based on the touch command, a test file is created under the NAS mounting path, whether the test file can be successfully deleted is detected, and a third detection result is obtained.

In this embodiment, a test file named "test_nas_date of day" may be created under the NAS mount path based on the command of "touch/NAS mount path/test_nas_date of day", and a test file named "test_nas_date of day" may be deleted under the NAS mount path based on the command of "rm-rf/NAS mount directory/test_nas_date of day", so that whether the test file can be successfully deleted may be detected, thereby obtaining a third detection result, and the third test result may display the writing capability of NAS mount information.

In step S204, if the first detection result, the second detection result, and the third detection result are all yes, it is determined that the NAS mounting information is in an available state.

In this embodiment, if the first detection result, the second detection result and the third detection result are all yes, it may be determined that the read-write function of the NAS mounting information is normal, that is, the NAS mounting information mounted on the current server is in an available state; if one of the first detection result, the second detection result and the third detection result is negative, determining that NAS mounting information mounted on the current server is in an unavailable state.

For the second embodiment of the present disclosure, the read-write function of NAS mount information mounted on the current server is detected based on the df command, the ls command, and the touch command, so as to determine whether the NAS mount information is in an available state, and facilitate subsequent determination of a NAS detection type corresponding to the NAS information based on the state of the NAS mount information.

Fig. 3 is a flowchart illustrating a network attached storage detection method according to a third embodiment of the present disclosure, as shown in fig. 3, the determining, in step S103, a NAS detection type corresponding to each piece of NAS information in the current server includes:

step S301, if the detection result is yes, it is determined that the NAS detection type corresponding to the NAS mounting information is the first type. The detection result refers to a detection result of whether the NAS mounting information is in a usable state.

Step S302, if the detection result is no, determining that the NAS detection type corresponding to the NAS mounting information is the second type.

Step S303, if the NAS information belongs to NAS configuration information and does not belong to NAS mounting information, determining that the NAS detection type corresponding to the NAS information is the third type.

In this embodiment, the NAS detection type includes a first type, a second type, and a third type, and in the case where NAS information is mounted on a current server and the NAS information is in an available state, it is determined that the NAS detection type corresponding to the NAS information is the first type; under the condition that NAS information is mounted on a current server and the NAS information is in an unavailable state, determining that a NAS detection type corresponding to the NAS information is a second type; in the case where NAS information is not mounted on the current server but fstab is written, that is, in the case where NAS information is only NAS configuration information and not NAS mounting information, it is determined that the NAS detection type corresponding to NAS information is the third type. The NAS detection type corresponding to the NAS information may be classified into a case where the NAS information is mounted on a current service, is in an available state, and is written into fstab, that is, the NAS information is both NAS mounting information and NAS configuration information, and a case where the NAS information is mounted on a current service, is in an available state, and is not written into fstab, that is, the NAS information is only NAS mounting information and not NAS configuration information.

To facilitate understanding of the third embodiment of the present disclosure, the classification of NAS information is shown by table (one):

form 1

As shown in table (one), in the case that NAS information is mounted on a current server, available and written to fstab, and NAS information is mounted on a current server, available and not written to fstab, NAS detection types corresponding to NAS information are all of a first type; under the condition that NAS information is mounted on a current server and is unavailable, NAS detection type corresponding to the NAS information is a second type; in the case where NAS information is not mounted on the current server but is written to fstab, the NAS detection type corresponding to the NAS information is the third type.

For the third embodiment of the present disclosure, based on whether NAS information is in an available state and the dependency relationship between NAS information and NAS mounting information and NAS configuration information, a NAS detection type corresponding to NAS information is determined, so that subsequent automated detection of NAS information based on a detection policy corresponding to each detection type is facilitated, thereby improving NAS detection efficiency, and saving a great amount of time and manpower.

Fig. 4 is a flowchart illustrating a network attached storage detection method according to a fourth embodiment of the present disclosure, as shown in fig. 4, the baseline detection of NAS information based on the first detection policy in step S104 includes:

Step S401, detecting whether the NAS mounting information meets the mounting standard or not, and obtaining a first baseline detection result.

In this embodiment, the NAS detection type is a first type, NAS information corresponding to the first type is NAS mount information, and whether the NAS mount information meets a mount standard is detected first, that is, whether all parameters in the NAS mount information match parameters in the mount standard is detected, so as to obtain a first baseline detection result. Specifically, the mounting standard may be shown in the following table (two):

form 2

Step S402, if the NAS mounting information has corresponding NAS configuration information, detecting whether the NAS configuration information corresponding to the NAS mounting information meets the configuration standard or not, and obtaining a second baseline detection result.

In this embodiment, corresponding NAS configuration information exists in the NAS mounting information, that is, the NAS mounting information is not only mounted on the current server but also written into the fstab, so that it is also required to detect whether the NAS configuration information corresponding to the NAS mounting information meets the configuration standard, that is, whether all parameters in the NAS configuration information match parameters in the configuration standard, so as to obtain a second baseline detection result. It should be emphasized that if the NAS mounting information does not have corresponding NAS configuration information, that is, the NAS mounting information is only mounted on the current server and is not written into fstab, the second baseline detection result is no.

Specifically, the configuration standard may be shown in the following table (three):

form (III)

Step S403, based on the communication of the ping command and the service IP address corresponding to the NAS mounting information, detecting whether the response time of the ping command is smaller than a third preset threshold value, and obtaining a third baseline detection result.

In this embodiment, based on the communication between the ping command and the service IP address corresponding to the NAS mounting information, it is detected whether the ping command can return response data in a time smaller than a third preset threshold, so as to obtain a third baseline detection result, where the third baseline detection result can represent performance of the NAS mounting information and performance of the network side. Specifically, the third preset threshold may be 5ms.

Step S404, detecting whether the number of files in the NAS mounting path corresponding to the NAS mounting information is larger than a fourth preset threshold value, and obtaining a fourth baseline detection result.

In this embodiment, if the number of files in the NAS mounting path exceeds a certain threshold, the read-write efficiency of the NAS mounting information will be low, so that whether the number of files in the NAS mounting path corresponding to the NAS mounting information is greater than a fourth preset threshold can be detected according to a command of "find/NAS mounting path-type d-size+fourth preset threshold", thereby obtaining a fourth baseline detection result. Specifically, the fourth preset threshold may be 10w (ten thousand).

In an embodiment, after step S404, whether the NAS snapshot corresponding to the NAS mount information is hidden may also be detected, so as to obtain a fifth baseline detection result, and specifically, whether the NAS snapshot is hidden may be determined according to the command of "ls-al/NAS mount path |grep.

Step S405, the first baseline detection result, the second baseline detection result, the third baseline detection result, and the fourth baseline detection result are all yes, and if not, the first NAS detection result is output, otherwise, the second NAS detection result is output.

In this embodiment, if the first baseline detection result, the second baseline detection result, the third baseline detection result, and the fourth baseline detection result are all yes, it is indicated that the NAS information baseline detection passes, the first NAS detection result may be output, and the first NAS detection result indicates that NAS mounting information is available and the baseline detection thereof passes; otherwise, outputting a second NAS detection result, wherein the second NAS detection result shows that NAS mounting information is available, and the problem types and the solution suggestions exist on the NAS mounting information base line.

In an embodiment, if the first baseline detection result, the second baseline detection result, the third baseline detection result, the fourth baseline detection result, and the fifth baseline detection result are all yes, indicating that the NAS information baseline detection is passed, the first NAS detection result may be output, where the first NAS detection result indicates that NAS mounting information is available and the baseline detection is passed; otherwise, outputting a second NAS detection result, where the second NAS detection result indicates that NAS mounting information is available, a problem type and a solution suggestion exist in a NAS mounting information baseline, for example, the second NAS detection result may be: NAS mount information is available, NAS snapshots are not hidden, normal use is not affected, and the contact storage group is set to invisible.

For the fourth embodiment of the present disclosure, if the NAS detection type is the first type, and at this time, the NAS information is mounted on the current server and in an available state, then only baseline detection is needed for the NAS information based on the first detection policy, that is, availability advanced inspection is performed for the NAS information, so as to obtain NAS detection results corresponding to the NAS information, and NAS may be optimized based on the NAS information availability based on the baseline detection results, so as to improve performance of the NAS.

step S501, detecting whether the service IP address corresponding to the NAS information is connected with the network or not based on the ping command to obtain a first checking result.

In this embodiment, the NAS detection type is a second type or a third type, NAS information is mounted on a current server and is unavailable, or NAS information is not mounted on the current server but is written into fstab, so that the NAS information is subjected to unavailability cause checking, firstly, whether a service IP address corresponding to the NAS information is network connected needs to be detected based on a ping command, and a first checking result is obtained, where the first checking result can represent whether a network side is normal or not and whether NAS mounting information or NAS configuration information is correct or not.

Step S502, if the first checking result is yes, detecting whether the NAS mounting path corresponding to the NAS information is a NAS shared mounting path, and obtaining a second checking result.

In this embodiment, if the service IP address corresponding to the NAS information can be ping-enabled, based on the command of the service IP address |grep/NAS mount path 1 "of the NAS information, it is detected whether the NAS mount path corresponding to the NAS information is a NAS shared mount path, and if the output of the showmount command is consistent with the NAS mount path contained therein, that is, the output is also" NAS mount path 1", it is indicated that the service IP address corresponding to the NAS information shares a remote path such as" NAS mount path 1", and the second checking result is yes.

In an embodiment, if the output of the showmount command is null, it indicates that the service IP address corresponding to the NAS information starts the NFS service, but a far-end path such as "NAS mount path 1" is not provided, NAS configuration information is wrong, or the NAS volume may be already recovered; if the output of the showmount command is other values, such as hang (no response) or err return, it indicates that the network port is not enabled, or the service IP address corresponding to the NAS information does not enable the NFS service.

Step S503, if the second checking result is yes, determining a corresponding target NAS based on the service IP address and the NAS mounting path, and detecting whether the white list of the target NAS contains the IP address of the current server, thereby obtaining a third checking result.

In this embodiment, if the service IP address corresponding to the NAS information can be ping-passed and the NAS mount path corresponding to the NAS information is a NAS shared mount path, determining a target NAS corresponding to the NAS information based on the service IP address and the NAS mount path, and detecting whether the white list of the target NAS includes the IP address of the current server, to obtain a third checking result. Specifically, if one ip in the current server ifconfig is in the white list, the third checking result is yes.

In an embodiment, if the target NAS determined based on the service IP address and the NAS mounting path exists, but the white list of the target NAS does not include the IP address of the current server, it is indicated that the white list authority is wrongly configured, and adjustment is needed; if the target NAS cannot be determined based on the service IP address and the NAS mount path, a command of "showmount-e service IP address" may be used to determine whether to add the whitelist.

And step S504, if the third checking result is yes, detecting whether the storage delay of the target NAS is smaller than a fifth preset threshold value, and obtaining a fourth checking result.

In this embodiment, if the white list of the target NAS includes the IP address of the current server, it is checked whether the storage delay of the target NAS is smaller than a fifth preset threshold, and a fourth investigation result is obtained, if the fourth investigation result is yes, the storage side performance of the target NAS is good; if the fourth checking result is no, it indicates that the target NAS storage side performance is poor, where the fifth preset threshold may be 30ms.

Step S505, if the fourth checking result is yes, detecting whether a mounting path of the target NAS exists on the current server, and obtaining a fifth checking result.

In this embodiment, if the first investigation result, the second investigation result, the third investigation result, the fourth investigation result, the fifth investigation result and the sixth investigation result are all passed, the investigation result corresponding to the NAS information passes, otherwise the investigation result corresponding to the NAS information does not pass.

With the fifth embodiment of the present disclosure, in the case where NAS information is mounted on the current server and is unavailable, or NAS information is not mounted on the current server but is written into fstab, the cause of unavailable NAS information may be obtained by checking the cause of unavailable NAS information based on the second detection policy, so that NAS may be maintained, and performance of NAS may be improved.

Fig. 6 is a flowchart illustrating a network attached storage detection method according to a sixth embodiment of the present disclosure, as shown in fig. 6, a NAS detection result corresponding to NAS information is determined in step S106, including:

in step S601, if the checking result does not pass, a third NAS detection result is output based on the checking result.

In this embodiment, no matter whether the NAS detection type is the second type or the third type, if the investigation result is not passed, a third NAS detection result is output based on the investigation result, where the third NAS detection result indicates that NAS information is unavailable, a cause of the NAS information being unavailable, and a solution suggestion, for example, the second NAS detection result may be: NAS information is not available, NAS storage performance is delayed by more than 30ms, please contact storage group colleagues for investigation.

Step S602, if the check result passes and the NAS detection type is the second type, outputting a fourth NAS detection result.

In this embodiment, the check result proves that the sixth check result is yes, that is, the NAS information is written in fstab and the NAS information meets the configuration standard, so that, in the second type, that is, in the case that the NAS information is mounted on the current server and is not available, a fourth NAS detection result may be output, where the fourth NAS detection result indicates that the NAS information is mounted on the current server and has abnormal functions, but the NAS information is written in fstab and the NAS information meets the configuration standard, and may be re-mounted after being unloaded.

Step S603, if the checking result passes and the NAS detection type is the third type, outputting a fifth NAS detection result.

In this embodiment, the check result indicates that the NAS information is not mounted on the current server, but the NAS information is written in the fstab and the NAS information satisfies the configuration standard, so whether or not the NAS information needs to be mounted on the current server can be confirmed by proving that the sixth check result is yes, that is, the NAS information is written in the fstab and the NAS information satisfies the configuration standard, and therefore, in the case of the third type, that is, the NAS information is not mounted on the current server but is written in the fstab, the fifth NAS detection result indicates that the NAS information is not mounted on the current server.

In the sixth embodiment of the present disclosure, based on the investigation result and the NAS detection type corresponding to the NAS information, the NAS detection result corresponding to the NAS information is determined, so that a more accurate and comprehensive NAS detection result can be generated, and the NAS can be maintained according to the NAS detection result, so as to improve the performance of the NAS.
