This post is a deep dive into recovering a lost or corrupted VMFS partition table. I’ll cover theory, common causes, diagnostic tools, and step-by-step recovery procedures. A VMFS datastore lives inside a primary partition (type 0xFB for VMFS3 or 0xFC for VMFS5/6) on a disk or LUN. The partition table (usually GPT, sometimes MBR on older systems) sits at the very beginning of the disk (LBA 0) and contains a small entry pointing to the start sector and length of that VMFS partition. vmfs partition table recovery
No recovery method replaces a verified backup. Use this knowledge to survive the crisis, then immediately double-check your 3-2-1 backup strategy. sudo apt-get install vmfs-tools Then scan: This post
voma -m vmfs -f /vmfs/devices/disks/naa.6001234567890 This tool is a lifesaver. It will scan the entire device for VMFS structures and report the found start LBA, block size, and file system version. If your disk uses GPT (most modern VMFS5/6), the primary GPT header at LBA 1 might be corrupt, but a backup GPT header resides at the last sector of the disk. The partition table (usually GPT, sometimes MBR on
esxcfg-info -s | grep -i vmfs Better yet, use the hidden voma tool (VMFS Offline Metadata Analyzer) in read-only mode:
We've all felt that cold sweat moment. You log into vCenter or ESXi, look at your storage devices, and see a datastore marked as or simply "Invalid partition table." Your VMs are inaccessible. Your heart rate spikes.
partedUtil restore /vmfs/devices/disks/naa.6001234567890 This command looks for the secondary GPT at the end of the disk and restores the primary. after a disk was mistakenly partitioned with a different tool. Method C: Using vgfs (Linux-based recovery) – For advanced users If ESXi tools fail, boot a Linux live CD (Ubuntu, SystemRescue) and install vmfs-tools :
