Rollback disk error

When users refer to the document "rollback disk" and "Delete Snapshot" methods for snapshot rollback, the following error occurs:

This problem is usually caused by reasons such as disk properties or disk status mismatch. Users can refer to the following steps to try to troubleshoot the analysis:

If the problem has not been solved, please contact after-sales technical support.

Check whether the instance associated with the relevant snapshot has done a "replace operating system" operation.

After the operating system is changed, the system disk of the instance will be automatically recreated with the new image, and the system disk ID will also be changed. Therefore, the original snapshot of the instance can no longer be used for rollback.

However, users can "create a custom mirror" based on the relevant snapshot, and then specify the custom mirror by "changing the operating system" to switch the instance to the appropriate snapshot state.

Check whether the instance has been stopped normally

Disk rollback operations can only occur if the instance has been stopped. Please refer to the following steps to confirm that the instance has stopped normally in the management console:

Open [Management console] → [ECS console]

Locate the instance to be operated by searching, etc.

Click the "manage" button on the far right of the corresponding instance ID or instance list to enter the instance management page

Verify that the instance state is in the stopped state.

Check whether the disk to which the snapshot is to be rolled back has a snapshot task in progress

To ensure data consistency, rollback operations are not allowed if the snapshot home disk has a snapshot task in progress.

Users can verify whether there is a snapshot task in progress by referring to the following steps:

Open [Management console] → [ECS console]

Locate the instance to be operated by searching, etc.

The corresponding instance ID or the "manage" button on the far right of the corresponding instance list goes to the instance management page.

Click the "this instance snapshot" link on the left to switch to the snapshot management page

Check to see if there are any snapshot tasks whose progress is not 100% and status is incomplete

If the user needs to force the termination of the relevant snapshot task in order to roll back the disk as soon as possible. After checking the appropriate snapshot, click the "Delete Snapshot" button below to terminate the snapshot task.
