Step 2: Use vmfs-fuse to try a read-only mount. # vmfs-fuse /dev/sde1 /mnt/recover → failed: "Unsupported VMFS version or corrupted heartbeat region" .
Maya stared at the now-green dashboard. Somewhere in the datacenter, a disk blinked its steady heartbeat. She smiled. Another VMFS ghost story, beaten by knowing exactly where VMware hides its backup superblocks. recover vmfs datastore
Maya grabbed coffee and her battle-tested Linux VM with vmfs-tools compiled. First rule of VMFS recovery: do not write anything to the affected LUN . She used a rescue Linux live CD on a physical host with HBA access. Step 2: Use vmfs-fuse to try a read-only mount
Step 1: Identify the device. fdisk -l showed /dev/sde as 12 TB, with partition 1 (VMFS) starting at sector 2048. Good—partition still there. Somewhere in the datacenter, a disk blinked its
Step 3: Deeper scan. She ran vmfs6-recover (part of vmfs-tools ). It parsed backup VMFS metadata—the first copy of the file system descriptor had been overwritten when the host re-scanned the "new" LUN, but VMware stores a second copy at offset 512 MB.
