i just tested it with a normal partition - that works -- so i think i
had to adress this to linux-lvm ...

a little more information:

kernel 2.4.5 with:

 reiserfs-2.4.5-knfsd (aus linux-nfs)
 linux-2.4.5-NFS_ALL 2001-06-03
 lvm-0.9.1_beta7-4 from 2.4.5aa2
 umount OOPS from AlViro

 reiserfs 3.6.25 

debian reiserfstools 3.x.0j-1



BTW: could someone tell me if there's a linux-hardware list? -- i've got
some issues with an 40G WD - yeah i know WD ,-)


wq - until next mail B-), l8r

There was a thread on reiserfs-list about write-caching on some IDE
drives. I think it was stated that WD did write-caching by default.
(and write-caching can make your filesystem inconsistent, and cause all
kinds of problems, if you happen to shutdown the machine at a bad time).

Check if write-caching is enabled with the hdparm command - turn it off
if it is. You should also run fsck to check if your filesystem is ok
(remember to back up first).

BTW: It isn't clear from your previous mail that this in fact a
filesystem problem. The output from fsck may or may not confirm that it
is. You could also strace your mpg123 process, to see exactly what it
tries to do and how it failes. You should also check /var/log/messages
for errors.

Though this is a big off-topic, I have compiled the 2.4.5 kernel with reiser
within it, but I moved back immediatedly  to 2.4.4 after I saw that
unmounting a Reiserfs LV causes an oops -- and a kernel hang when trying to
unmount further Reiserfs LVs... ouch... not strange that there might be data
corruption with this kernel version!

Known problem. Get the fix from the download section of

hmmm, it seens to fixed in at least 2.4.5-ac9. Currently, I have a
2.4.5-ac13 running with Reiserfs LV. So far, no problems.
