Re: Re: Ext-3 on Alpha - experience sought...

I've been running xfs now for a few weeks and that seems to be fairly reliable, though
it has had very little loading (compilling mozilla is about the heaviest load I given it)
and I haven't tried power cycled the machine with a mounted xfs drive.

All in all though xfs seems pretty good. I untarred the entire mozilla tarball and it was
about 20% faster than ext2 (a very dubious benchmark but it gives an idea). It also takes
about 0.5 second to fsck a 3GByte partition, deletions are *very* fast (less than a second
on an 800MByte file, cf. about 15 seconds on extfs)

Just my 2 cents.
