Partition Table | Esxi Repair

Her hands were still shaking, but she smiled. The partition table repair had worked.

esxcli system maintenanceMode set --enable false echo "All restored. Go to sleep, Lena." She didn’t sleep. She wrote documentation: “How to repair ESXi partition table using partedUtil – a near-death experience.” esxi repair partition table

It was 2:00 AM when Lena’s phone buzzed with the alert she dreaded most: . All VMs on that host had frozen. She’d been the new senior sysadmin for only three weeks. Her hands were still shaking, but she smiled

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

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.

Then: esxcfg-volume -l → “VMFS UUID 5d2a8b2e-fc0f2b10-1234-7845c4f5a9b1” appeared.
