Journaling file systems revisited

[Scott Prive]

FYI - 

ReiserFS works well for some, but a Google search on "reiserfs corruption" (an AND search) produces 3000 hits. "ext3 corruption" gives you 400 hits, and "xfs corruption" just 123. I wouldn't call this a scientific measure, of course :-)

After ReiserFS chewed up my /home partition last year, I found online it's happened to lots of folks. It's just my personal opinion, but I would look between XFS, and ext3 (perhaps JFS... I haven't looked at JFS yet)

I may use Reiser for my backup file systems since they are mounted and 
unmounted at least once a night.
