Nothing special, I have tens of such filesystems. With a < 3.0 xfs_progs
you should be able to run xfs_repair with 8 GB of RAM. With newer
versions the memory requirement are even lower.
I often needed at times to run older xfs_repair on big filesystems with
only 1 GB of RAM, and using lots of swap (3, 4 GB or more) did the
trick, though of course it was slow as a caterpillar swimming in
molasses.
