Recover Vmfs Partition Table May 2026

ls /vmfs/devices/disks/ Look for the affected LUN. It will look something like: naa.600601605a281b00c1d5b86c5a3be011

df -h /vmfs/volumes/ If the datastore shows but VMs are not visible, run:

List all storage devices:

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:

partedUtil get /vmfs/devices/disks/naa.xxxxxxxxxxxx Example output: 60801 255 63 976773168 recover vmfs partition table

esxcfg-volume -l If the disk shows a known VMFS UUID but not mounted, try:

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. ls /vmfs/devices/disks/ Look for the affected LUN

Now create partition:
