Hi, I'm using a similar setup, but without Samba for the moment, though I am looking forward to using the native samba module[1]. So far I have not had any major problems caused by the setup itself, but do bear in mind that when the failover IP switches from one machine to the other the existing TCP connections will be reset; this may or may not be a problem. Because of this I use the "soft" and "intr" mount options on the NFS clients. Some may have other recommendations.

No idea here, but just a warning, XFS is the recommended and most tested filesystem for use with GlusterFS. There were some issues in the past with EXTx filesystems.
