Usage Guidelines

If the disklog is lost, running this command can:

  • Repair inconsistent stripes in all the allocated space in the disk domain.
  • Repair inconsistent stripes in the specified chunk group (CKG).
  • Repair inconsistent stripes in a certain extent in the CKG.

Before running this command, ensure that no disk out or fault events occur. If these events exist, run this command after the global disk reconstruction is complete.

Example

Repair inconsistent stripes. Before running this command, ensure that the reconstruction task is complete, disk domain ID is 0, and no disk out or fault events or data reconstruction or copy tasks in the disk domain.

developer:/>change disk_domain stripe_verify_restore disk_domain_id=0 run_state=start 
DANGER: You are about to repair inconsistent stripes in disk_domain. This operation repairs parity data for RAID 3, 5, and 6 and does not change data bits. For RAID 10, this operation selects a disk in the mirror group, uses data on the disk to repair other disk in the mirror group, and restores stripe consistency after the repair. However, data accuracy cannot be ensured. If disk out or fault events occur during the repair, data may be lost. 
Suggestion: Confirm the operation before performing it.
