Recover Vmfs Partition Table May 2026

If the partition table becomes corrupted—due to accidental overwriting, failed resizing operations, controller issues, or human error—the datastore becomes inaccessible, and all VMs hosted on it appear lost. The good news: In many cases, without data loss.

Now create partition:

fdisk -l /vmfs/devices/disks/naa.xxxxxxxxxxxx ESXi has a built-in recovery tool that can restore a VMFS partition table if the VMFS superblock is intact. Method A: Using partedUtil restore First, check if a VMFS volume is detectable: recover vmfs partition table

df -h /vmfs/volumes/ If the datastore shows but VMs are not visible, run: If the partition table becomes corrupted—due to accidental

partedUtil get /vmfs/devices/disks/naa.xxxxxxxxxxxx Example output: 60801 255 63 976773168 Method A: Using partedUtil restore First, check if

partedUtil set /vmfs/devices/disks/naa.xxxxxxxxxxxx 1 2048 976773167 AA31E02A-400F-11DB-9590-000C2911D1B8 0 Then rescan:

: The partition table is small, but losing it can take down entire virtual infrastructure. Treat it with the respect it deserves. Need help? Always test recovery procedures in a lab environment before applying to production systems.
