If you want to use the cluster in an active/passive configuration, then
you can even use normal non-clustered LVM, you just have to set-up the
cluster accordingly. Or like you said, use CLVM, it is easier to
maintain and safer (less prone to admin errors) in a clustered
environment.

Subject: [rhelv5-list] NFS / CIFS cluster question
I am preparing to build a 2-node cluster to server NFS and CIFS (Samba)
to a farm of servers (primarily non-Linux). I have the systems
clustered, and CLVM is working fine on my SAN disks.
Now it occurs to me that I have 2 ways to do the shared filesystems:
1) Use GFS (which I have no experience with), which allows me to have
simultaneous read/write access on all cluster nodes (not really a
requirement)
2) Use CLVM, and let the cluster manage who can write to the filesystems
(i.e., which node they get mounted on, exported from, etc)
Since I am implementing this as an HA cluster, not a load-balancer, do I
really care about GFS? Is it simpler to set up an NFS/CIFS cluster with
GFS? Only the active node has any reason to ever have write access to
the disks.
Can someone enlighten me, please? I'm open to opinions, especially
fromanyone with experience in doing the same thing.
Thanks,
Kevin
