Esxi Repair Partition Table -

“Partition table,” she whispered. The previous admin had left no documentation, but she knew ESXi stored its boot banks on a small FAT16 partition, then a core dump partition, then a VMFS data partition. If the GPT table got corrupted, the host would see the disk as raw.

She logged into the DCIM console. The HP ProLiant DL380 was still running, but the local VMFS datastore was inaccessible. She tried ls /vmfs/volumes/ — empty.

ls /vmfs/volumes/5d2a8b2e... → all VMs were there. She restarted the VMs one by one. By 2:30 AM, services were restored.

She mounted it: esxcfg-volume -M 5d2a8b2e-fc0f2b10-1234-7845c4f5a9b1

She didn’t panic. ESXi has a built-in repair tool: partedUtil fix but only if you know the original partition layout. She didn’t. She did have one clue: a working identical host in the same cluster.

The command completed silently. She held her breath and typed: partedUtil get … – the table matched the healthy host.
