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
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.
