Recover Vmfs [upd]

Recovering a VMFS (Virtual Machine File System) volume is a critical process for restoring access to virtualized data after accidental deletion, partition loss, or storage corruption. Because VMware ESXi hosts use a proprietary file system, standard operating systems like Windows or Linux cannot natively read or recover this data without specialized tools. Common Scenarios Requiring VMFS Recovery

Set the : Change the partition type to fb (VMware VMFS). recover vmfs

Attach the LUN as a raw disk to a Linux VM. Install testdisk → select the disk → Intel/EFI GPT → Analyze → Deeper Search. Write recovered partition table. Recovering a VMFS (Virtual Machine File System) volume

| Tool | Capability | |------|-------------| | | Reads VMFS3/VMFS5/VMFS6, recovers deleted VMDKs | | R-Studio for VMware | Parses VMFS metadata, reconstructs corrupted datastores | | DiskInternals VMFS Recovery | Recovers files from formatted or damaged VMFS | | Klennix VMFS Recovery | Specializes in partial overwrites and corrupt journals | Attach the LUN as a raw disk to a Linux VM

Recovering a VMFS datastore is viable in most accidental deletion scenarios, provided that the underlying storage blocks have not been overwritten. The primary method involves reconstructing the partition table to align with the original VMFS boundaries. However, this procedure carries significant risk, and engaging VMware Global Support Services (GSS) is highly recommended for production environments where data integrity is critical.

Immediately stop writing any new data to the affected LUN or disk to prevent overwriting existing VMDK files.
