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

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


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

[root@harry:/var/log] cat hostd.log | grep “VMFS volume”
2016-04-01T16:51:14.942Z warning hostd[337F2B70] [Originator@6876 sub=Hostsvc.DatastoreSystem opID=7e27fc0f-5d18-42e9-881e-32243c0ab973-1223-ngc-25-e4-30-bf0c user=vpxuser] VMFS volume [/vmfs/volumes/56fea6e4-8714148f-7b99-000c291899c1] of version [0] is not supported.


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


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!


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


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

[root@harry] restart

    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.
