I moved all my myth recordings from a 250GB PATA disk formatted as
ext3 to a 250GB SATA disk formatted as jfs. Since then the initial
start time after I select a recording to watch has increased
dramatically - typically 10-15 seconds before the video appears. I
don't know if this is normal, but it's not what I expected.
As for corruption, my system hung at the weekend and almost every file
that was open on another jfs disk ended up in lost+found after the
fsck. (My system hangs often enough that I have fsck on by default
after an unsafe shutdown. And yes I know this needs to be resolved.)
Fortunately my system disk is still ext3.
I think I won't be using jfs for future disks. I may yet go through
the pain of backup/reformat/restore for the ones I have.
