Recently I made the choice of using IBM’s journaled file system (JFS) as the file system for a new 320 GB sata harddrive. Usually I’m a reiserfs kind-of-guy but I’ve been reading recently that deletes of large files are faster on JFS and with MythTV’s .19 release I’ve suffered a slight wait while large files were deleted. Of course MythTV’s .20 release now mitigates slow file deletes and JFS wasn’t needed, but how was I to really know I wasn’t missing out unless I actually tested it for myself? This of course is subjective but on an Athlon 3200 (~2ghz) I can’t really see any difference. As I understand it JFS is less CPU intensive while reiserfs is more cpu intensive but is also more reliable in the event of a system crash. It seems that my system is plenty fast enough to run reiserfs with out any percieved hit in performance.
Would you believe that soon after using JFS I experienced my first crash, in a different state, via ssh? Guess which partition came up dirty? Luckily a quick fsck.jfs -v -f /dev/sda1 solved the problem. Please remember to un-mount a drive before running fsck!
