If only rhel supported ZFS, that'd be the ticket. XFS would probably do it, you'd have to either compile a kernel or grab one from something like CentOS 5. Haven't used GFS.

Right now my SAN max volume capability is 15 TB. So, I'd like to use LVM and tie several physical volumes together into a sigle logical volume. As stated, the cluster will be serving this volume up via NFS and the data is random files but I estimate the number of files to be around 70 million per 10 TB of data. 1) What file system should I use? Ext3 appears to have a 4k block size limitation which puts my max size at 8 TB. Reiserfs doesnt appear to be supported. XFS?? GFS?? 2) Is LVM safe for this type of deployment? 3) Any other thoughts? Thanks! Terry
