Vmfs __top__ - Recovery

Once the partition is recreated, attempt the mount again:

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. recovery vmfs

First, unmount the datastore (force if necessary). Once the partition is recreated, attempt the mount

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). First, unmount the datastore (force if necessary)

Stay calm. Run esxcfg-scsidevs . Use vmkfstools -V . And whatever you do,

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.
