Recovery — Vmfs |top|

Create a new partition (assuming a standard 1MB offset):

Once the partition is recreated, attempt the mount again: recovery vmfs

partedUtil setptbl /vmfs/devices/disks/naa.6000c29c4c5a2b1c gpt partedUtil add /vmfs/devices/disks/naa.6000c29c4c5a2b1c 1 2048 [End_Sector_Number] To find the end sector: partedUtil getUsableSectors /vmfs/devices/disks/naa.6000c29c4c5a2b1c Create a new partition (assuming a standard 1MB

esxcfg-scsidevs -l Look for the device with the correct size and LUN number that does not have a filesystem label next to it. Now, we attempt a manual mount. Use the -r flag for read-only to ensure we don't make the situation worse. Have you ever recovered a "dead" VMFS datastore

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 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 getptbl /vmfs/devices/disks/naa.6000c29c4c5a2b1c If the output is gibberish or empty, the partition table is zeroed out. You need to know the old partition size. Usually, a VMFS datastore uses the entire LUN (Partition starting at sector 2048).
