That's a lot of data to lose. :-) As for your question, I'd use ext4. It has caught up a lot with XFS and it's THE file system supported by RHEL and Fedora. -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro

Theres one big issue with NFS that requires a workaround... XFS requires 64 bit inodes on a large file system ('inode64'), and by default, NFS wants to use the inode as the unique ID for the export, this doesn't work as that unique ID has to be 32 bits, so you have to manually specify a unique identifier for each share from a given server. I can't remember offhand what the specific option is, but you can specify 1, 2, 3, 4 for the share identifiers, or any other unique integer. if you only export the root of a file system, tis is not a problem. this problem is squarely an NFS implementation problem, that code should have been fixed eons ago. -- john r pierce N 37, W 122 santa cruz ca mid-left coast

Their implementations of filesystems are completely different. If you use a CentOS NFS server, I'd recommend ext4. In benchmarks, I often see XFS perform better than ext4 in specific tests. JFS rarely does well. However, the last time I used XFS was for a system running Zoneminder. Benchmarks let us to believe that XFS would be a better filesystem, but in our actual implementation it couldn't keep up. The application couldn't delete data quickly enough when the volume was nearly full, so the volume would fill up and the system would fail. We only got it working reliably after switching to ext4.
