Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method, a device, equipment and a storage medium for detecting a fault of a storage link, which are used for accurately detecting the fault link between a storage main system and a rear-end hard disk.
Referring to fig. 1, a schematic flow chart of a method for detecting a failure of a storage link according to an embodiment of the present invention is shown; as can be seen, the fault detection method specifically includes the following steps:
s101, acquiring a link physical state of a storage link; the storage link is a link for accessing the target hard disk by the storage main system through the target controller;
specifically, for the storage device with dual-control redundancy design, the access of the storage main system to the rear-end hard disk is uniformly distributed on the two controllers, so if the controllers include the controller 1 and the controller 2, the storage link of the storage main system to access the hard disk includes the following two links: the storage main system accesses a first storage link of the hard disk through the controller 1, and the storage main system accesses a second storage link of the hard disk through the controller 2, so that if the storage link is accurately detected to be a fault link through the scheme, a link switching operation can be executed to switch the link accessing the hard disk to another storage link.
It should be noted that, when the link physical state of the storage link is obtained in the present solution, the link physical state of the storage link may be specifically obtained with a predetermined time as a period. Such as: and setting the detection period to be 5 minutes, and executing the fault detection method in the scheme every 5 minutes so as to find out the fault link in time and avoid performance loss and data risk when IO operation is executed through the fault link. Of course, the predetermined time period representing the detection period described in the present application may be set by self-definition according to actual requirements, and is only 5 minutes for illustration.
S102, judging whether the physical state of the link is an off-line state; if not, executing S103; if yes, executing S104;
this application provides three-layer fault detection mode for accurate detection link trouble, promptly: the memory link is checked sequentially through a physical layer, a link layer and an application layer. Specifically, when the link detection is performed based on the physical layer, the physical state of the link of the storage link is detected, if the storage link is in an offline state, the fault is directly marked, the link switching is triggered, and the subsequent detection step is not required to be executed; if the state is not the offline state, the subsequent detection steps are continuously executed so as to accurately detect the fault of the storage link.
S103, judging whether the storage link is a fault link or not based on a link layer and an application layer; if yes, executing S104; if not, ending the flow;
it should be noted that, when determining whether the storage link is a failed link based on the link layer and the application layer, the method may specifically include the following steps:
determining whether a CRC error count corresponding to the memory link exceeds a predetermined threshold;
if yes, judging the storage link to be a fault link, and triggering link switching operation;
if not, judging whether the hard disk login state corresponding to the storage link is login failure or not; if the login state of the hard disk is login failure, judging that the storage link is a failure link, and triggering link switching operation; otherwise, the flow ends.
Fig. 2 is a schematic diagram of a link fault monitoring process disclosed in the embodiment of the present invention; it can be seen that, when the link failure is periodically detected, whether the physical state of the link of the physical layer is the offline state is judged, if yes, the link is marked as the failed link, and the link switching operation is triggered; in addition, when judging whether the storage link is a fault link based on the link layer, the CRC error count in the link layer is judged whether to reach a preset threshold value; it should be noted that the CRC error count is the number of data transmission errors between the hard disk and the motherboard, so that each hard disk has a corresponding CRC error count, and the corresponding CRC error count of the storage link is the CRC error count of the hard disk corresponding to the storage link. And, the present application sets a predetermined threshold corresponding to the CRC error count in advance, if the predetermined threshold is exceeded, it indicates that the storage link is failed, marks the link as a failed link, and triggers a link switching operation, such as: if the error count is 2 times in 1 second and the predetermined threshold is 3 times in 1 second, it indicates that the memory link is not failed. Further, if the storage link is not judged to be in fault in the link layer level, the method and the device can also continue to judge from the application layer level. For example, in the present application, a login state of a hard disk may be detected, and if the login state is a failed state, a link failure is marked, and link switching is triggered.
And S104, judging the storage link to be a fault link, and triggering link switching operation.
Specifically, after determining that the storage link is a failed link, the triggered link switching operation specifically includes: switching the storage link to: the link of the target hard disk is accessed through a controller other than the target controller. As described above, if the controller includes the controller 1 and the controller 2, the storage link of the storage host system accessing the target hard disk includes the following two links: the storage main system accesses a first storage link of the target hard disk through the controller 1, the storage main system accesses a second storage link of the target hard disk through the controller 2, and if the current storage link is the first storage link, the first storage link is switched to the second storage link after the link switching operation is triggered, so that the storage main system accesses the target hard disk through the second storage link.
In summary, the application provides a three-layer fault detection scheme, a first layer judges a physical layer state, a second layer compares error counts of link layers, a third layer judges a hard disk logic state, a fault link is detected in a layer-by-layer progressive mode, if any layer meets a fault judgment condition, the fault link is marked, and the fault link is quickly switched to another link, so that performance reduction and data risk caused by IO execution on the original link are avoided, and the usability of the whole storage system is improved.
Based on the foregoing embodiment, in this embodiment, after determining that the storage link is a failed link, the method further includes: and generating alarm information of the storage link as a fault link. In addition, when the alarm information that the storage link is the failed link is generated, the failure cause information of the storage link needs to be determined first, and the failure alarm information corresponding to the storage link needs to be generated by using the failure cause information.
It can be understood that, after the storage link is determined to be a failed link, in order to enable a manager to know the state of each link in time and repair the failed link in time, alarm information needs to be generated, and the manager is prompted to have a link failure phenomenon in a mode of reporting the alarm information. Also, the failure warning information in the present application may include detail information of the storage link, failure discovery time, failure cause information, and the like, where the detail information indicates which hard disk the link is specifically accessed through which controller, the failure discovery time is a time when the storage link is determined to be a failed link, and the failure cause information may be determined according to a condition for determining that the storage link is a failed link, such as: if the storage link is determined to be a failed link according to the physical state of the link passing through the physical layer, the failure cause information is: if the link physical state is an offline state and is determined to be a failed link, or if the storage link is determined to be a failed link through the CRC error count of the link layer, the failure cause information is: if the CRC error count is too large, the link is determined to be a fault link, or if the storage link is determined to be a fault link through the hard disk login state of the application layer, the fault cause information is as follows: and determining the fault link as the hard disk login state is a failure state.
In summary, the monitoring scheme for the link failure of the main storage system and the rear-end hard disk provided by the scheme can select judgment bases from a physical layer, a link layer and an application layer respectively, so that the failure detection accuracy is improved, and the performance loss and the data risk caused by the link failure are reduced. In addition, by the mode of reporting the fault alarm information, the administrator can know the fault reason information of the fault link in detail according to the fault alarm information, so that the fault link can be repaired in a targeted manner, and the repairing speed is improved.
