If errors are found, you can attempt a repair using the fix flag (note: VMware highly recommends a backup first). voma -m vmfs -f fix -d /vmfs/devices/disks/ : Recovering Corrupted VMDK Files
Administrators typically use SSH to access the host and run voma in "check" or "fix" mode on a specific device or partition.
voma -m vmfs -f check /dev/disks/<DeviceName>:<PartitionNumber>
In such cases, or salvage files using raw recovery tools.
: ESXi VMFS repair is possible but fragile . The platform lacks a native, reliable repair utility. Best practice is prevention via redundant storage, proper shutdowns, and regular backups. If repair is needed, use vmfs-tools (read-only first) or commercial recovery tools — and prepare to restore from backup.
| Risk | Details | |------|---------| | | Unlike ext4 or NTFS, ESXi has no vmfs.fsck command. | | Cluster awareness | Repair attempts on shared datastores must ensure all hosts unmount it first. | | No journal replay | VMFS does not journal metadata; sudden power loss may cause irreparable damage. | | Version mismatch | VMFS3 tools may not work on VMFS6. Always match tool to VMFS version. |
If this reports errors, voma can sometimes fix them (rare for severe corruption, usually used for metadata consistency).
