Recovery Vmfs Partition New! [Android Secure]

Recovering a VMFS partition is like recovering a standard FAT or NTFS partition; it requires understanding VMFS’s on-disk layout and recovery tools that respect its unique structures.

VMware Virtual Machine File System (VMFS) is a high-performance cluster file system designed for storing virtual machine disks, snapshots, and configuration files. A VMFS partition can become inaccessible or "lost" due to:

If standard VMware tools fail, consider high-level partition management alternatives like SourceForge's listed alternatives , which include tools like or Stellar Data Recovery that support various virtual disk formats. VMFS Partition Table Recovery - DiskInternals recovery vmfs partition

TestDisk is highly effective at scanning disks for lost partition tables.

Before attempting recovery, it is vital to understand why the partition is missing. The recovery strategy often depends on the cause: Recovering a VMFS partition is like recovering a

Sometimes the partition is intact, but the datastore is simply unmounted. SSH into the ESXi host and run:

If the LUN is visible but not listed as a VMFS volume, check if the partition table is readable using: VMFS Partition Table Recovery - DiskInternals TestDisk is

Inputting incorrect sectors can destroy data.

However, these tools carry risk. Always work in Read-Only mode whenever possible, and once the data is recovered, perform a storage vmotion to a healthy datastore to ensure the recovered volume is stable for production use.

While advanced scanning usually requires a Live Linux CD (see Phase 3), experienced admins often recall standard partitioning layouts.

For cases where the VMFS superblock (metadata) is corrupted, open-source tools like vmfs6-tools on a Linux machine can be used.
