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.
vmkfstools -V -r /vmfs/devices/disks/naa.6000c29c4c5a2b1c:1 If the metadata is corrupt (files show up, but VMs won't power on), you need the VMFS Offline Metadata Analyzer ( voma ).
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. recovery vmfs
esxcfg-volume -l # Find the volume name esxcfg-volume -U [Volume_Name] Run the repair. You must unmount the volume first, or you will crash the host.
Stay calm. Run esxcfg-scsidevs . Use vmkfstools -V . And whatever you do, Have you ever recovered a "dead" VMFS datastore
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).
We’ve all been there. You log into vCenter, click on a datastore, and your heart sinks. Instead of the happy green "Normal" status, you see "Not Mounted" or "Corrupted." Maybe an ESXi host lost power during a SAN firmware update, or someone accidentally deleted a LUN mapping. Always ensure you have current, restorable backups before
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.
