Unless you're using a shared/switched storage system, you'll probably also want to check out http://www.drbd.org/

The SUSE HA Cluster guru (Lars Marowsky-Bree) hangs out on Linux-HA (heartbeat). For SLES he officially supports Linux-HA and DRBD so i assume he is the best resource you will come across. Thus if I were you, I would wander over to the Linux-HA mailing list. Actual answers: Assuming you are wanting to setup a redundant Samba server, there are some issues at failover time. DRBD ensures the data is duplicated and heartbeat will move the IP for you and manage DRBD, but any open sockets get closed. As I understand it, this is also a problem for pure Windows failover clusters. Apparently a lot of windows software assumes that sockets are unreliable and simple reconnect on a dropped socket, but it is not a seamless transition. Again, I think the best place to ask is the Linux-HA mailing list. Greg -- Greg Freemyer The Norcross Group Forensics for the 21st Century
