Metadata ((new)) — Recover Vmfs

VMFS does have an fsck like ext4. Instead, VMware relies on journal replay on mount. To force replay:

first 3 to 5 GB of a volume, scanning this initial segment can often reconstruct the entire file system structure. vmfsrecover.com +2 Native Recovery Tools (vSphere/ESXi) Use these built-in commands for initial diagnostics and safe recovery attempts: VOMA (vSphere On-disk Metadata Analyzer): Checks VMFS metadata consistency and can identify errors in the heartbeat or partition table. Command: voma -m vmfs -f check -d /vmfs/devices/disks/<device_ID> Force Rescan: Forces the ESXi host to look for new or changed storage devices. Command: esxcli storage core adapter rescan --all Volume Mounting: Attempts to mount a volume if it is seen as a snapshot or secondary datastore. Command: esxcfg-volume -M Broadcom support portal +3 Specialized Metadata Recovery Software If native tools fail, third-party software uses proprietary algorithms to reconstruct damaged or reinitialized VMFS headers.
