This article explains the Physical Disk Health - Metadata Health check in the vSAN Health Service, and provides details on why it might report an error.


Q: What does the Physical disk Health - Metadata health check do?

If this health status is not green (OK), vSAN has encountered an issue reading the metadata of the disk, and, therefore, cannot use this physical disk.

Q: What does it mean when it is in an error state?

The disk may have suffered a physical drive failure. This check could also fail due to a software problem. When this health check fails, it indicates that the disk is not usable and any data stored on the physical disk is currently unavailable. This can also impact the capacity of the vSAN datastore.

Note: This health check test can fail intermittently if the destaging process is slow, most likely because vSAN needs to do physical block allocations on the storage devices. To work around this issue, run the health check once more after the period of high activity (multiple virtual machine deployments, etc) is complete. If the health check continues to fail the warning is valid. If the health check passes, the warning can be ignored.

Q: How does one troubleshoot and fix the error state?

The physical drive failure must be addressed. For more information on procedures for replacing failed components, including disk drives, see Administering VMware Virtual SAN Guide.
If there is no failed drive, or there is difficulty identifying a failure drive, contact VMware Support. For more information, see How to file a Support Request in My VMware (2006985).
