You are not using a clustered filesystem, right?
No.
I can imagine that would be one of the advantages of RH's clustering, since you don't have to mount a filesystem in that case for a machine that just crashed - it would safe time...
I'm not sure if Red Hat even supports a clustered FS at this time. It certainly didn't when we set up the system more than two years ago.
I thinks that's exactly why they bought Sistina with GFS - and GPL'd it. Does anybody know how it works with cyrus-imapd?
If you are interested in using a shared filesystem on a SAN for server redundancy, then you could try using a replicated Murder (Cyrus 2.3). Such a config is running at a local University using 4 Sun servers and QFS (Sun's SAN filesystem) on a Hitachi fibre array.
I haven't tested this with GFS, but if it has correct file locking and memory mapping support, then it might work.
I'm fairly confident that SGI's XFS would work, although I haven't tried it.
