I'm using JFS, haven't ever had problems. Though I also haven't had issues with other
filesystems either. To Grandparent: What sort of oddities does JFS have?

Really, I consider filesystems to be one of those things that if you're getting frequent
updates, there's probably something wrong.

My experience: I used JFS as system disk for a debian testing or unstable distro for a few
years. The disk was always pretty tight on space (80 % or so), so I guess fragmentation took
its toll with the massive volume of updates coming in almost every day. In the end days, the
filesystem had abysmal performance -- I recall that doing anything at all on it basically
stalled the computer into a long-term disk-crunching session.

These days I have switched to ext3. I have figured it doesn't really make any kind of
practical difference, and it's best to use the thing that most others use as well. I haven't
noticed similar performance loss with time in any other filesystem I have used.
