What is the name of the command line utility used for checking VMFS5 metadata corruption?

  1. vmkfstools --check

  2. voma

  3. vmfsanalyzer

  4. esxcli vmfs check

The correct answer is: voma

The command line utility used for checking VMFS5 metadata corruption is known as VOMA (vSphere On-disk Metadata Analyzer). This tool is specifically designed to inspect and evaluate the integrity of the metadata within VMFS volumes, helping to identify potential corruption issues. VOMA can analyze the VMFS file system without mounting it, making it an ideal choice for addressing metadata concerns while maintaining data integrity and availability. While other options may seem related to VMFS management or function, they serve different purposes. For instance, vmkfstools is mainly used for managing virtual disks and snapshots, and it includes various functions but does not focus solely on metadata corruption checking. Similarly, esxcli and vmfsanalyzer command utilities play roles in managing or troubleshooting VMFS, but they do not provide the specific analysis of metadata integrity that VOMA does.
