I’m running ESXi version 6.1 U1 and Dell Virtual Storage Manager  (VSM)version 4.5.2.974. I added a datastore to  the cluster using VSM and on 2 of my hosts I got the following alert:

vsmversion

deprecatedvmfs

Enables SSH on the host and check out the logs.

In /var/log/hostd.log , I found the error:

 

 warning hostd[xXxXxX] [Originator@6876 sub=Hostsvc.DatastoreSystem opID=123456-789-abc-def user=vpxuser] UpdateConfigIssues: Deprecated VMFS filesystems detected. These volumes should be upgraded to the latest version.

When I created the datastore, I did select VMFS 5, so I wasn’t sure why this error appeared.

selectedvmfs5

According to vmware KB2109735, this is a known issue in version 6.0 and there is no resolution. Just restart the management services and the message goes away.

 

#  /etc/init.d/hostd restart
#  /etc/init.d/vpxa restart

Then the message goes away.

 

*note*

This only happens to me when I create a datastore with VSM. If I present a disk from my array, set up the iSCSI connections and rescan, I don’t get this message. Your mileage may vary.
