My main concern is the amount of RAM I need for a fsck of the xfs fs.
Last time I search for the xfs requirements, I found the rule of
thumb: 2 GB RAM for 1 TB of disk storage + some RAM per x inodes.

A real world example: we have a ~70TB filesystem, with ~70M inodes and xfs_repair uses about 13-15GB of memory IIRC (haven't run a repair in a while) using a recentish 2.8.x version.

Hope that helps.
