Recover Vmfs -
If the datastore was accidentally deleted but the data remains, you can manually restore the partition table via the ESXi shell using fdisk or partedUtil .
Once the datastore is mounted:
: Run fdisk -l /dev/disks/naa... to confirm the partition table is missing or empty. Recreate the Partition : Run fdisk -u /dev/disks/naa... (for VMFS3/5). Create a new primary partition (type n , then p , then 1 ). recover vmfs
: Use esxcfg-scsidev -c list to find the console device path (e.g., /dev/disks/naa.600... ). If the datastore was accidentally deleted but the
Immediately stop writing any new data to the affected LUN or disk to prevent overwriting existing VMDK files. Recreate the Partition : Run fdisk -u /dev/disks/naa
VMware Virtual Machine File System (VMFS) is the clustered file system used by ESXi hosts to store virtual machines. Datastore corruption can occur due to sudden power loss, improper VMFS version upgrades, storage array errors, accidental deletion, or failed LUN resizing. This guide provides a structured approach to diagnosing, repairing, and recovering a corrupted or inaccessible VMFS datastore.
