I do not think its jfs causug yyour backends to hand.  my myth system is on 
a remote raid5 server (it was running red hat)  i tried tp upgrade it one 
day and things went a bit weird.  its still ran but yum and the like would 
no longer work.  (this is only my file server/web server)  I ran ext3 for a 
while but hated the slowness in deleting 1+gig files.  I switched to JFS and 
I have never had a problem.    (my file server was online for 4 year without 
a reboot.  I have since redone this machine with CentOS 4 .   Also my Myth 
frontend/backend attaches to this fileserver via NFS (as well as my windows 

I think there was something else causing your wows with the hangs.  I have 
been extremely happy with JFS

I used JFS for a while and I believe it was causing my backend to
bail out every day or two. I lived with waking up in the morning and
restarting the backend. When the file system completely crapped out
and I lost all my recordings, I reformatted as ext3 and it's been
solid ever since. I'm running a 64bit system which might have
something to do with it. I just wanted to post my experience in case
anyone else is having this issue as well and as a warning for someone
looking for a new file system.
