Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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 technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
An embodiment of the present invention further provides a method for correcting a drive letter of windows cloud migration, where as shown in fig. 1, the method for correcting a drive letter of windows cloud migration includes:
step S101: and acquiring the corresponding disk identifier of each logical volume in the original windows. Specifically, each logical volume in the original windows corresponds to its own drive letter, which is an identifier of the disk storage device corresponding to the logical volume.
Step S102: and recording the drive letter into a file system corresponding to the logical volume. Specifically, to solve the problem of disheveled disk identifier after the migration of the Windows cloud, the disk identifier of each logical volume of the original Windows is recorded first, for example, a wmic command (Windows Management instruction) may be used on the original Windows to collect the disk identifier of the logical volume and record the disk identifier to a respective file system, where the advantage of recording to the respective file system instead of recording to a specific file system is that no additional hard disk serial number modification tool (volumeid) needs to be recorded because the volumeid changes after the Windows is migrated to the target end, and the file system always corresponds to the logical volume before and after migration.
In practical application, after recording the drive letter to the file system corresponding to the logical volume, the drive letter corresponding to each logical volume in the original Windows can be confirmed by creating a vss consistency snapshot, and then the file system recorded with the drive letter is synchronously migrated to the target end, which is only the cloud platform after cloud migration of the original Windows.
Step S103: and when the original windows cloud is migrated to the target end, mounting the system partition of the original windows, starting the virtual machine of the target end, and when each logical volume is mounted, acquiring a new disk identifier corresponding to the logical volume. Specifically, after the original windows cloud is migrated to the target end, i.e., the cloud platform, the file system is written into the cloud hard disk, the virtual machine of the target end of the system partition of the original windows is mounted, the logical volume is mounted to start the windows system, and then the new disk identifier actually corresponding to the mounted logical volume in the cloud hard disk is obtained.
Step S104: and judging whether the new drive letter is consistent with the drive letter recorded in the file system. Specifically, the method comprises the steps of reading a drive letter recorded in a file system and judging whether the new drive letter is the same with the drive letter, namely judging whether the drive letter corresponding to the logical volume has the problem of disorder of the drive letter, if so, judging that the drive letter of the logical volume in the windows after migration is accurate, and if not, judging that the drive letter has the problem of disorder.
Step S105: and when the new drive letter is inconsistent with the drive letter recorded in the file system, unloading the logical volume, and re-mounting the logical volume according to the drive letter recorded in the file system until all the logical reel letters are corrected. Specifically, when a logical volume has a disk identifier that is wrong, the logical volume is unloaded first, and then the logical volume is mounted again according to the original disk identifier until all the logical disk identifiers are corrected, that is, the disk identifiers of all the logical volumes are consistent with the disk identifier in the original windows, so as to ensure that all the application programs can run normally.
By executing the steps S101 to S105, the drive letter correction method for windows cloud migration provided by the embodiment of the present invention records the drive letter corresponding to each logical volume in the original windows to the corresponding file system, obtains the new drive letter corresponding to each logical volume when the new windows mount each logical volume and starts up after the original windows cloud is migrated to the target end, and unloads the logical volume with the wrong drive letter and re-mounts the logical volume according to the original drive letter by comparing the new drive letter with the drive letter recorded in the file system corresponding to the logical volume, so that the drive letter disorder occurring after the windows cloud migration is automatically corrected without human intervention, and the normal operation of the original application program can be ensured.
Specifically, in an embodiment, before obtaining a new drive corresponding to the logical volume, the method for correcting a drive for windows cloud migration further includes the following steps:
step S201: and acquiring the total number of the logical volumes in the original windows. Specifically, when a user selects to perform cloud migration on an original windows, it is first required to select migration content of the original windows, that is, which system disks and system files stored therein are migrated, for example: and migrating the C disk, the D disk and the E disk cloud of the original windows to a target end, wherein the total number of the logical volumes is the sum of the number of the logical volumes stored in the C disk, the D disk and the E disk, and the total number can be directly calculated according to a migration disk selected by a user.
Step S202: and recording the total number to the system partition of the original windows. Specifically, because the system partition is a partition for starting a window and does not change before and after cloud migration, the total number of the logical volumes in the original window is recorded in the system partition, and when the window is restarted after cloud migration, the total number of the logical volumes can be directly obtained. The total number indicates that the original windows cloud migration is the total number of the migrated logical volumes, so that whether the drive letter correction service of all the logical volumes is completed or not can be judged conveniently in the follow-up process, the accuracy of the drive letter of each logical volume of the windows after migration is ensured, and the windows after migration can be started normally.
Step S203: and judging whether the number of the mounted logical volumes is consistent with the total number. In practical application, a drive letter is continuously occupied in the process of mounting each logical volume on line, if a drive letter correction operation is performed in the process, a situation that the corrected drive letter is occupied by other logical volumes mounted on line may occur, so that delay or failure occurs in the drive letter correction, and the efficiency of the drive letter correction is affected, therefore, it is necessary to determine whether all the logical volumes are mounted completely, and the drive letter correction is started only when all the logical volumes are mounted completely, specifically, whether all the logical volumes are on line is determined by scanning whether a system disk on line is consistent with a migration disk selected by a user at a target end, for example: and scanning whether all the logical volumes of the C disk, the D disk and the E disk exist at a target end, so as to judge whether the mounted logical volume number is consistent with the logical volumes stored in the C disk, the D disk and the E disk.
Step S204: and when the number of the mounted logical volumes is consistent with the total number, acquiring a new drive letter corresponding to the logical volume. Specifically, if the number and the total number of the mounted logical volumes are consistent, it is described that all the logical volumes are mounted on line, and at this time, the disk identifier correction is started, so that the situation that the disk identifiers are occupied mutually does not occur, and therefore, a new disk identifier corresponding to the logical volume starts to be acquired, and the disk identifier correction service is performed.
Step S205: when the number of the mounted logical volumes is inconsistent with the total number, the process returns to step S203 after a preset time interval until the mounting of all the logical volumes is completed. In practical application, if the number of the mounted logical volumes is inconsistent with the total number of all the logical volumes, it is indicated that there is no logical volume online, a certain time needs to be waited for, and all the logical volumes are online.
The above steps are processes for avoiding that when a drive letter of a certain logical volume is corrected, the corrected drive letter is occupied by a newly mounted logical volume, and therefore it is necessary to judge whether all the logical volumes are mounted completely, that is, after all the logical volumes are on-line, the new drive letter of the logical volume is obtained, and the drive letter of the logical volume is corrected.
Accordingly, in another alternative embodiment of the present invention, in the above step S105, when the new drive letter is inconsistent with the drive letter recorded in the file system, all the logical volumes are unloaded to avoid the situation that the logical volumes occupy the drive letter with each other, and then all the logical volumes are re-mounted according to the drive letter recorded in the file system, and the optical disc drive can be floppy-mounted these last times to avoid occupying the drive letter when the logical volumes are re-mounted.
Specifically, in an embodiment, before obtaining a new drive corresponding to the logical volume, the method for correcting a drive for windows cloud migration further includes the following steps:
step S301: and when the original windows cloud is migrated to the target end, writing the repair mark into a preset modified drive letter service file, wherein the preset modified drive letter service file is a modified drive letter service installed in the original windows and is used for storing the repair mark. Specifically, since the original windows does not need to modify the drive letter before cloud migration, the preset modified drive letter service file has no repair mark, that is, the preset modified drive letter service file is empty, and the installed modified drive letter service exits after detecting that no repair mark exists, so that the start of the original system is not affected. Step S302: and judging whether the preset correction drive letter service file stores a repair mark or not. Specifically, the original windows, the target windows started by the target end for the first time and the target windows started by the target group for the non-first time can be distinguished by judging whether the preset disc character correcting service file stores the repairing marks or not, disc character correcting service is performed only when the target windows started by the target end for the first time, and if the target end is not started for the first time, disc character correction is completed after cloud migration, so that disc character correcting service is not required, and normal starting of a system is not influenced.
Step S303: and when the preset correction drive symbol service file stores the repair mark, acquiring a new drive symbol corresponding to the logical volume. Specifically, if the preset modified drive letter service file stores the repair mark, it indicates that this time starting of the system is the first time starting after the original windows is migrated to the target end, and at this time, the migrated system may store the problem that the drive letter is messy, so that the drive letter modification needs to be performed before starting the system to ensure normal operation of the system.
Specifically, in practical application, the drive letter needs to be corrected only when the windows cloud is started for the first time after being migrated to the target end, and the problem of confusion of the drive letter does not exist when the original windows is started or when the windows cloud is restarted after being migrated, so that the original windows is provided with the modified drive letter service file, that is, the original windows and the target windows started at the target end for the first time are distinguished, and because the original windows do not have the repair mark in the modified drive letter service file before the cloud is migrated, the installed modified drive letter service can exit after detecting that no repair mark exists, the start of the original system cannot be influenced, and the drive letter modified service can be started only at the target windows, that is, the new drive letter corresponding to the logical volume is obtained.
Specifically, in an embodiment, after all logical reel letter correction is completed, the method for correcting a reel letter for windows cloud migration further includes the following steps:
step S401: and clearing the repair mark stored in the preset modified drive letter service file. Specifically, after all logical reel letters are corrected, if windows is restarted at the target end, since the disordered reel letters of the windows are already corrected, the problem of disordered reel letters does not exist, and therefore, the repair mark stored in the preset modified reel letter service file needs to be cleared, and at this time, the installed modified reel letter service exits after detecting that no repair mark exists, so that the start of a new system is prevented from being influenced. In practical application, by means of clearing the repair flag in the preset modified disk service file, if the system is not started for the first time at the target end, it indicates that the disk letter modification is completed after cloud migration, there is no repair flag in the preset modified disk letter service file, the installed modified disk letter service exits after detecting that there is no repair flag, and the restart of the system is not affected,
the method for correcting the drive letter of windows cloud migration provided by the embodiment of the present invention will be described in detail with reference to specific application examples.
As shown in fig. 2, in a scenario that a windows is migrated from a source cloud to a cloud, cloud migration software may deploy an agent on each logical volume vm of a source (i.e., an original window), then collect and record corresponding information on the source through the agent, that is, a file system corresponding to each logical volume in the original window, where a drive letter of the corresponding logical volume and a system partition recording the total number of all logical volumes to be migrated are recorded in the source, then create a vss consistency snapshot for all file systems and system partitions and synchronize data to a transport receiving end corresponding to the cloud, where a cloud hard disk having the same size as that of the original window partition is already mounted on the transport, the transport writes all received data into the cloud hard disk and then injects a correction flag into a preset correction drive letter service file, and after detecting that a virtual machine exists in the cloud hard disk, first determine whether all logical volumes to be migrated are all online, and acquiring new disk identifiers of all the logical volumes until all the logical volumes to be migrated are mounted on line, then judging whether the new disk identifiers are consistent with the disk identifiers recorded in the file system of the original windows, if the disk identifiers are inconsistent, starting a disk identifier correction service, unloading all the logical volumes, and re-mounting all the logical volumes according to the disk identifiers recorded in the file system to repair the disk identifiers of the cloud host, so that the problem that the disk identifiers are disordered when the original windows cloud is migrated to a target end and started for the first time is solved, and the normal starting of the cloud host is ensured.
