The limit is how much memory a 32-bit process can allocate - it's not
a limit of xfs_repair itself.

OK, that makes sense. I'll keep my 64 bits xfs_repair at hand :)


As a rule of thumb with a fairly recent xfs_repair, you need approx
128MB RAM per TB filesystem size (but it also depends on number of
inodes too).
