Yes, at work we have 3 Oracle DBs on Linux systems.

Yes, the three DBs are run off two RAC instances with an OCFS2 partiton
each and 5 shared ASM disks each.

I can't vouch for the stability of Oracle as I've only inherited the
sysadmin side of the system. When the system was setup the admins had a
lot of late nights debugging driver, hardware, os and application
problems. The system is reasonably stable now but any downtime for
maintinance takes hours when the same maintinance could be done on a
Master/Slave system in minutes.

If all you need is HA look at a Master/Slave system first. If you need
load balancing be prepared for a monster system which eats you time.

Oracle's rman backup system supports RAC instances. I'd suggest you
stick with that for your backup/restore procedure. This makes the disk
managment a moot point.
