Try GFS2 (yum install gfs2-utils)
I think GFS2 is provided in the base RHEL5 server channel.

Subject: [rhelv5-list] support for very large volumes 30 TB --
filesystems,architecture
Hello,
I am going to be implementing an NFS cluster on RHEL5 x86_64
that I would like to serve up a single very large volume (one volume for
application reasons). 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
