No. Ctdb can't do TCP session failover. Ctdb has
capabilities to trigger the client to very quickly reconnect
under all circumstances. But the client will be able to tell
that a node failed.
With SMB2 there will be support for so-called durable file
handles which make the client OS completely hide a failover
from the client applications. But that's not there yet in
