Hello, everybody!
We have a VMware vSphere 5.1 environment and we have an external NFS datastore connected to one of the our hosts with OS distros and similar stuff. Recently on the side of NFS server a firewall was activated and erroneously its config haven`t any NFS enabled. So our datastore went to inactive state. After correcting this error, I successfully recreated NFS datastore under a new name, but now I couldn`t remove the old one! From vSphere Client menu I see all the possible commands for that datastore, except the Unmount one. When I use esxcli command, it successfully completed but after it I have even more strange result - vSphere Client shows: number of hosts connected to datastore - 0, number of VMs - 2. But in both "connected" VMs virtual CD-ROMs are changed to Client device, there are no files from that (or other NFS) datastore in there properties!
So, how could I manually delete this corrupted stuff now?
