The following tools are standard for diagnosing and repairing VMFS structures: Broadcom support portalhttps://knowledge.broadcom.com Corruption seen on VMFS datastore due to overwritten data recover vmfs metadata

Use dd and hdparm to check if basic partition table is readable: tail -100 /var/log/vmkernel

VMFS (Virtual Machine File System) is a file system used by VMware ESXi to store virtual machines (VMs) on a datastore. The VMFS metadata is a critical component of the VMFS file system, containing information about the layout and organization of the datastore. However, in some cases, the VMFS metadata may become corrupted or lost, making it difficult or impossible to access the VMs stored on the datastore. In this report, we will discuss the importance of VMFS metadata, the causes of metadata loss, and methods for recovering VMFS metadata. In this report, we will discuss the importance

Command: voma -m vmfs -f check -d /vmfs/devices/disks/<device_ID> Force Rescan: Forces the ESXi host to look for new or changed storage devices. Command: esxcli storage core adapter rescan --all Volume Mounting: Attempts to mount a volume if it is seen as a snapshot or secondary datastore.

VMFS (Virtual Machine File System) is a clustered file system designed by VMware to store virtual machine disks. Like any file system, it relies on metadata—a "map" that tells the system where files are located, how much space is free, and the state of the volume.
