Just to add a detail: I've had problems on systems with 1GB RAM fsck'ing
a file system that was ~3TB: it failed with OOM, but did not with 2GB.
I've successfully fsck'ed ~5TB filesystems with 4GB RAM (4 spindles, 20-30
minutes) and 11TB with 8GB (6 spindles, 40 or so minutes). You might be
able to do less, but you can at least do it with that.
