voma -m vmfs -f fix -d /dev/disks/naa.xxxxxx:1 ⚠️ Always take a backup before running fix . Major corruption may require full recovery tools. When native methods fail, use dedicated VMFS recovery software:
esxcli storage core adapter rescan --all From vSphere Client: . 3.2 Restore VMFS Volume from Remaining Partition Table If the VMFS partition is missing but the LUN still has valid GPT/MBR: recover vmfs 5 datastore
partedUtil get /dev/disks/naa.xxxxxx If the table is empty but you know the start sector (usually 2048 or 128), recreate: voma -m vmfs -f fix -d /dev/disks/naa
esxcli storage vmfs snapshot resignature -l <original_label> Or mount as snapshot: recover vmfs 5 datastore
| Structure | Sector offset (relative to partition start) | |-----------|-----------------------------------------------| | VMFS FDC (File Descriptor) | 1-63 | | Heartbeat region 1 | 128 | | Heartbeat region 2 | 256 | | File/directory tables | 4096+ |
