Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version

By | 02/04/2016

Today while working in my Lab I was seeing following warning message on my Esxi host:
Deprecated VMFS volume(s) found on the host. Please consider upgrading volume(s) to the latest version

1

This error occurred just after I added a new shared LUN from my openfiler appliance.

If you SSH to Esxi host you will see error similar to as shown below in the /var/log/hostd.log file

As per VMware KB-2109735 this is a known issue affecting vCenter Server 6.0

Cause:

This issue occurs because the version of the filesystem is not known during the initial detection. Therefore, comparing it against the list of valid filesystems does not return a match.

Starting with vSphere 6.0 the VMFS3 version is now deprecated, but in my case all block based datastores were already at VMFS version 5!

Resolution:

There is currently no resolution available for this issue but there is a workaround which helps in getting rid of this error.

Workaround:

Restart the management agents on the impacted hosts to clear the warning using the DCUI or the local command line.

[root@harry] services.sh restart

I hope you enjoyed reading this post. Feel free to share this on social media if it is worth sharing. Be sociable :)

    Please note that it appears that Update 2 fixes this issue when you update both VC and Hosts. I just added 3 datastores and did not encounter this warning.

      Hey Chris,

      Thanks for the heads up on this. I will test vSphere 6 U2 soon in my lab.
