I have also run xfs_repair on a 17TB XFS filesystem on a machine with about 4GB of memory. It ran fine in less than one hour (~30m IIRC; that filesystem is on CentOS 6).

with XFS at least (and probably ext4) what counts is how many files are in the file system more than the absolute size. if you have 17000 1gb files, its one thing, if you have 17,000,000,000 1K files, its another thing entirely.

Good point. Just for a data point, I've probably got on the order of a few dozen million files of widely varying sizes on this particular filesystem. (So more than 10 million files but fewer than 100 million.)
