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. She used a rescue Linux live CD on
The datastore reappeared in the vSphere Client. VMs showed as "unknown"—expected. She browsed the datastore: all VM folders, .vmdk , .vmx files intact.
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.
