That's a good link - thanks.
Man, there's so many factors to think of it. I was especially boggled to hear
that the disk drive cable I'm using might be a culprit. Arggh! Who can keep
track of all this?
as well as a write-up explaining why you shouldn't use ext3. It
basically comes down to the fact that ext3 is using a separate file to
handle the journal. What this means is that as you write your audio
data, every once in a while, the system has to write to a different file
in a separate location on the hard drive.
Yeah, that's what I was concerned about.
It will depend on how close
the files are physically to each other, disk latency, and a host of
other things but, eventually, you will see problems with ext3. It's not
hard to convert to reiserfs (instructions (destructions?) are included
on the above page) so why not.
Looks like you can't convert non-destructively though. What a pain.
Reiser journals are kept with (as part
of?) the files - you don't have to run fsck after a crash. A real
intersting thing to note is that reiserfs actually seems to be faster
than ext2 for what we're doing.
fsck'ing is a pain, yes, but if it needs to be done too often there's other
problems :-) so for me, ext3 is nice, but not needed I think. I have had bad
shutdowns over the years quite often on ext2, and although it's not nice to
wait for it to come back up, I've never had a case where I had to do a manual
repair.
