The Virtual Machine File System (VMFS) is incredibly resilient, but it isn't invincible. The good news? You just need to know the right commands and the right order of operations. partedUtil setptbl /vmfs/devices/disks/naa
Have you ever recovered a "dead" VMFS datastore? What trick worked for you? Let me know in the comments below. Always ensure you have current, restorable backups before attempting filesystem repairs. The author assumes no liability for data loss resulting from the misuse of these commands. The good news
voma -m vmfs -f fix -d /vmfs/devices/disks/naa.6000c29c4c5a2b1c:1 voma will scan every file descriptor, fix chain corruption, and rebuild the allocation map. This tool has saved my bacon more times than I can count. Once the repair completes (or the mount succeeds), rescan again and verify the heartbeat.
First, unmount the datastore (force if necessary).
