we are using XFS with CentOS 6.latest on 80TB file systems, works quite
well. handles a mix of many tiny files and very large files without
any special tuning.
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.
