Hi all,
We are currently running a NFS-based server centric setup. I would like to set up something where I can easily have more than one redundant server, security/authentication (this part seems a little flaky with NFS, at least did several years ago), with the capability to easily add/remove servers as necessary, take redundant servers down for maintenance, etc. Total volume we expect to run on the server side will be somewhere between 10-30 TB. The servers will most likely be CentOS machines, the clients mostly Linux machines with some Macs and possibly Windows (the latter part not that important).
Any insight, thoughts and recommendations will be much appreciated.
Thanks.
Boris.

Have you considered an NFS cluster based on pacemaker/openais/corosync? See http://www.clusterlabs.org/. One possible config is an active/passive cluster using NFS on top of DRBD. I've never clustered samba, but it looks like others have done it: http://dev.gentoo.org/~wschlich/src/sys-cluster/heartbeat-scripts-4/ocf-ra/samba
Google will show you various problems with active/active clusters related to both GFS2 and samba. Don't try to have your NFS servers also be NFS clients.
For reasonable security/authentication, you'd probably want to integrate with kerberos.

I think about buying a HP LeftHand SAN wich is an iSCSI cluster sytem. One could use that as backend for two failover hosts serving GFS via NFS.

I'm still exploring options for a similar situation and at the moment gluster seems to fit the requirements.
