I think you will run into locking problems when you loadbalance samba
using LVS. I might be wrong though, but consider:
clientA opens fileA (through LVS) on serverA
serverA locks the file
clientB opens fileA (through LVS) on serverB
serverB doesn't know about the lock and will grant access to clientA
when it shouldn't
Take a look at CTDB: http://ctdb.samba.org
We have an implementation of CTDB using RR DNS, the advised method for
loadbalancing Samba.
Good luck!
