Citrix XenServer Error: Detaching SR – General backend error

After a power outage we ran into some errors after bring everything back up.  When trying to reconnect a CIFS share on our NetApp filer, we got the following errors.

Jan 3, 2014 10:40:10 AM Error: Repairing SR CIFS ISO library On Netapp - Unable to mount the directory specified in device configuration request
Jan 3, 2014 10:40:54 AM Error: Detaching SR 'CIFS ISO library On Netapp' from 'SOME POOL' - General backend error

At first I thought the issue was Xenserver not bring joined to the Active Directory domain. But I was wrong, the issue was the NetApp wasn’t joined to the AD domain. So make sure everyone is on the domain and you may get rid of these errors. For us, the issue was the time on the NetApp was off by 6 minutes and was causing errors when trying to join AD (time needs to be with in sync within 5 minutes).
