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
