Vmware Recovery Vmfs Partition Jun 2026

Check the current partition status: partedUtil getptbl /vmfs/devices/disks/

VMware Virtual Machine File System (VMFS) is a high-performance cluster file system used by ESXi hosts to store virtual machines, templates, and ISO files. Accidental deletion, partition table corruption, or metadata damage can render a datastore inaccessible. This paper outlines diagnostic steps and recovery methods for VMFS partitions, focusing on software-based approaches.

RAID card failures or disk sector corruption. Step 1: Initial Troubleshooting and Assessment vmware recovery vmfs partition

Never rely on RAID or snapshots as your only backup. Use solutions like Veeam or Synology Active Backup to keep copies of VMDKs on separate hardware. If you'd like to dive deeper, let me know: What version of ESXi are you running (6.7, 7.0, or 8.0)? Is the storage Local DAS, iSCSI, or Fibre Channel ? Do you have a current backup of the VMs?

Boot a Linux live CD and install vmfs-tools : RAID card failures or disk sector corruption

Report: VMware VMFS Partition Recovery VMware's Virtual Machine File System (VMFS) is a high-performance cluster file system specifically optimized for storing virtual machine disk (VMDK) files. Because standard Windows and Linux operating systems cannot natively recognize VMFS volumes, recovering data from a damaged or deleted partition requires specialized procedures or third-party tools. 1. Common Recovery Scenarios

VMFS is a high-performance cluster file system designed specifically for virtual machines. It allows multiple ESXi hosts to read and write to the same storage simultaneously. When a partition goes "missing," it is rarely the data itself that has vanished. Usually, the issue lies within the partition table (MBR or GPT) or the VMFS metadata. Common reasons for partition loss include: If you'd like to dive deeper, let me

Sometimes the partition is intact, but ESXi refuses to mount it because it thinks the volume is a copy. This happens frequently after hardware migrations or firmware updates. Run the command: esxcli storage vmfs snapshot list

Recovering a VMFS partition is possible in most accidental deletion or partition table corruption scenarios. The first step is always to stop writing to the disk. Native ESXi commands ( esxcfg-volume , partedUtil , vmkfstools ) often succeed. For complex metadata damage, Linux‑based vmfs‑tools or commercial software provides a second line of defense.

For VMFS6, the starting sector is typically . The GUID for a VMFS partition is AA31E02A400F11DB9590000C2911D1B8 . Step 4: Using Professional Recovery Software
