I have copies of Mark Knecht's benchmarks on my web page : http://myweb.cableone.net/eviltwin69/Arcana.html 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. 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. 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. Jan On Sat, 2003-02-15 at 06:47, Frank Barknecht wrote:

Converting to reiserfs is a pain but no fsck'ing on boot is worth it. If you're not going to use that though I would use ext2. Like you, I've never lost an ext2 disk due to a crash. I have let the smoke out of a couple of disk drives though :-) Jan On Sat, 2003-02-15 at 08:44, Larry Troxler wrote:

Hallo, Mark Knecht hat gesagt: // Mark Knecht wrote: How is the state of reiserfs, when it comes to repair broken filesystems? This was a serious issue some months ago and really kept me from installing reiser, and made me use ext3. Are the reiserfsck-tools stable now? And what's this with the ext3-LL-conflict? Will I run into problems when using a more current kernel than 2.4.18? ciao -- Frank Barknecht _ ______footils.org__

Hallo, Jan Evil Twin Depner hat gesagt: // Jan Evil Twin Depner wrote: At work, where we have a SuSE samba server, we had a crash on a reiserfs disk about a year ago, where we would have needed stable fsck tools. Then the reisertools weren't much help to our more capable sysadmin, because they just seemed not finished. Since then I don't trust reiser very much, but maybe it has changed now. At work we're still running reiserfs, though, even on out web server... ;) Maybe I really should change, at least my freshly installed laptop... ciao -- Frank Barknecht _ ______footils.org__

aha - is this why you were asking about usb audio cards a while back? which one did you get in the end? greets matthew

I only use reiserfs on my data drive. I use ext3 on my root drive. If you're doing any serious recording you need a dedicated data drive. I *really* wouldn't use reiserfs on the root drive. Jan On Sat, 2003-02-15 at 16:01, anton wrote:

I subscribed to the XFS reflector for a while and found that the number and type of problems I was hearing about were too scary for me, so I passed for now. They tell me that it will be a file system option in 2.5.X, and indeed it's there in the make sconfig build script, but I have not tried it. No time. XFS is supposed to be very good for large files, while reiser is best for small files. Hence, we could hope that XFS eventually becomes a good option. Look for 2.7.X or 2.9.X..... Mark

Rick, Are/were you using XFS for your system drive, your audio drive, or for some other storage purpose? Mark On Sun, 2003-02-16 at 09:19, Rick Taylor wrote:

The only filesystem I lost in that time was due to my stupidity (I forgot to apply a VFS fix for the VFS-eats-filesystems bug that was in 2.4.5. I knew about the bug, I knew about the patch. I was stupid). ext3 has been shown to have more variance in the latency than other filesystems. Perhaps this is an issue for you. I've used Reiserfs and ext3 on small personal disks, up to many-drived RAID arrays at work. I use Reiserfs whenever I'm building the system up from scratch because it's faster for streaming operations and deletes. I use ext3 whenever I have to convert a filesystem for journalling because I don't have to backup and restore. There's really very little reliability difference between the two. -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon. It is a Water Cannon. He fires Holy-Water from it.

Mark, Have you tried the Qt GUI for the bundle scripts? Jan On Sat, 2003-02-15 at 19:04, Mark Knecht wrote:

Hallo, Jan Evil Twin Depner hat gesagt: // Jan Evil Twin Depner wrote: This sounds like a good compromise. On my laptop, where in the future the real audio stuff is going on (maybe live, who knows) I have two partitions, one for /home (which is me and all sound stuff) one for the /-rest, both around 10 GB in size. Both are ext3 currently, but It would be very easy to change the /home-partition to reiserfs, because there is enough free space on / to move /home there temporarily. Looking a Marks fs-benchmarks, ext3 is first of all bad at disk writes. I don't write much outside /home, only to /tmp and I could symlink that over to /home/tmp or such. Does this all sound like a good strategy? Changing / to reiser would be much harder and would require repartitioning if I don't want to have /boot on reiser, which I wouldn't want to for named reasons. ciao -- Frank Barknecht _ ______footils.org__

The problem appeared first on 2.4.20-pre5 (pre4 was the last I tested that was working fine). A fix was found be Andrew Morton after 2.4.20 final came out and is inlcluded in the recent 2.4.21-pre series (I don't remember which prex was the first to include it). 2.4.19 was fine. -- Fernando
