I'm not sure if cifs client filesystem will retry after a disconnect.
Other people on this list will be able to give advice about that.
I think that's the most likely issue. You could check a couple of
* What does the ARP table on the client say after the failover? Does
it match the NIC on the new node hosting the IP?
* Do you see the CIFS connection get reset if you do a tcpdump or
This certainly isn't a configuration I have tested. For Linux clients
I have tested NFS.
peace & happiness,
