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.
