| ID | Requirement | |----|--------------| | F5 | Support (pre-check). | | F6 | Provide granular repair options: | | - Repair FBM inconsistencies | | - Rebuild FDC from secondary copy (if available) | | - Replay/recover journal entries | | - Fix orphaned file descriptors | | - Remove stale lock entries | | F7 | Safe mode: Only repair metadata; never touch user data blocks. | | F8 | Force mode: For severely damaged volumes (skip some checks). | | F9 | Automatic file system checkpoints (if underlying storage supports snapshots). | vmfs repair file system
The volume must be unmounted or have no active I/O for a reliable check. 3. Attempt a Repair If the disk appears empty or the partition
You can run a read-only check to identify errors: | | F8 | Force mode: For severely
Note: This attempts to fix the filesystem label. If successful, run vobd or check /var/log/vobd.log to see the result.
Before running a repair, you must find the identifier for the backed device (NAA ID) or the specific partition. Log into the ESXi shell via SSH.
