CIFS share may become unavailable when the CIFS server is in normal mode

When the CIFS server is running in normal mode and a CIFS share is brought online, if the MSDFS referral IP for that share faults and is not able to come online on any other node, the share becomes unavailable. In such cases, the CIFS share has the wrong definition in the smb.conf file and hence remains inaccessible. This issue can occur during an upgrade or when the NIC hosting the MSDFS IP of the CIFS share gets faulted on all nodes. This issue does not occur when the CIFS server is in the CTDB mode.

(IA-22339)

Workaround:

Stop and start the CIFS server.
