Jenna looked at her laptop, then back at him. “Neither did I. Until tonight.”
Sometimes the partition is intact but the host's view is stale. A simple HBA rescan can refresh the volume's status.
It was 2:00 AM on a Tuesday when Jenna’s phone buzzed with the dreaded alert: vmware repair vmfs partition
Use a third-party tool if the ESXi kernel cannot mount the volume.
"When dealing with VMFS partition corruption, the margin for error is zero. Most generic partition recovery tools fail because they don't understand the VMFS file system structure. This solution correctly identified the backup superblock and rebuilt the partition table without touching the underlying VMDK files. Jenna looked at her laptop, then back at him
If a volume is detected as a snapshot (often after a hardware change), it may need to be "resignatured" to be mounted. This assigns a new UUID to the volume, allowing the ESXi host to recognize it as a unique datastore. Step 3: Manual Partition Table Recovery
The first step is determining if the issue is a logical VMFS error or a mounting conflict. 1. Check for PDL and APD States A simple HBA rescan can refresh the volume's status
vmfs-fdisk -c /vmfs/devices/disks/naa.60012345
VMware provides a built-in tool called VOMA to check and fix minor metadata issues.
Next, she used vmfs-fdisk —a hidden gem in ESXi’s recovery toolkit—to scan for VMFS signatures:
voma -m vmfs -d /vmfs/devices/disks/DEVICE_ID:PARTITION_NUMBER -s /tmp/analysis.txt -func query
