I have active-active samba, and what I've found is this... Due to state issues, failover WILL cause any 'during failover' file operations to fail. But on the other side of that, the way that samba deals with file moves/copies ensures that no data will be lost.. simply, restart the operation immediately after the error. In our system, the error occurs the moment that the failover machine takes over. other than having to redo any 'in failover' operations, the failover is completely transparent to clients.. if no operations are occuring, then there will be no sign to clients that a failover occured.
