She opened a fresh terminal and typed:
Her hands were still shaking, but she smiled. The partition table repair had worked.
Then: esxcfg-volume -l → “VMFS UUID 5d2a8b2e-fc0f2b10-1234-7845c4f5a9b1” appeared.
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.”
One of the most heart-stopping moments for a system administrator is rebooting an ESXi host only to find it fails to boot, displaying errors regarding missing boot devices or corrupt partitions. Often, the root cause is not a failed hard drive, but a corrupted Master Boot Record (MBR) or GUID Partition Table (GPT).
Here is a step-by-step guide to repairing a partition table on ESXi:
The partition table on ESXi is a critical component that defines the layout of the storage devices, including the location of VMFS (Virtual Machine File System) partitions, which store virtual machine data. A partition table is a data structure that contains information about the partitions on a storage device, such as the partition type, size, and starting sector.
This guide walks through the process of repairing the ESXi partition table using the installation media. This non-destructive process attempts to rewrite the boot loader and partition table without affecting the VMFS datastores residing on the same disk.
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.
Once the installer has loaded, follow these steps carefully:
The ESXi partition repair tool built into the installation media is a robust feature designed specifically for this scenario. By selecting the disk and pressing , administrators can often restore a failed host to service in minutes without the need for a full reinstall and restore from backup.
Before attempting any partition table repair, ensure you have a valid backup of your virtual machines. While the repair process is designed to preserve data partitions (VMFS), disk operations always carry a risk of data loss. Proceed at your own risk.
