In the similar case 28+ years estimated for pass 0 turned into 208 hours total operations after speedup patch was applied. We plan to include it into reiserfsprogs 3.6.6-pre1, but if you need that urgently, tell us. > so I'm curious if maybe fscking in background is planned? - idea is not new > and bsd guys say that they have it for freebsd 5.0 in ffs. This is not possible for reiserfs, I think. reiserfs have non-constant metadata location , so while you can certainly check fs consistency of some snapshot, you cannot fix it because all the real data might have ben shifted to other blocks, old blocks might have been already freed and so on.
