[dm-devel] Disk io deadlocks during large-file io



Disk io deadlocks during large-file io.

During heavy disk io involving creating large files, some parts
of the kernel locks up. In most cases all disk output becomes
impossible, but sometimes you can write small things to disk, like
echo > test.txt might work sometimes. On reiserfs the lockups tend to be
more severe. The problem only occurs when i have both disks in my device
mapper mirror installed. if i remove one of the SATA cables, everything
works perfectly , except that devicemapper complains that the mirror is
degraded.

dm_unplug_all and dm_table_unplug appears to be present in the call
stack for at least one process for all complete dmesg's i have manged to
collect.

Tested versions from 2.6.11.7 up to 2.6.12-rc3 all show the same behaviour.

Kernel version:
Linux version 2.6.12-rc3 (root bar) (gcc version 3.4.3-20050110 (Gentoo
Linux 3.4.3.20050110-r2, ssp-3.4.3.20050110-0, pie-8.7.7)) #1 Thu Apr 21
14:25:14 CEST 2005

Output from <alt><syrq>-T when the deadlock has occured is provided at
the end of this mail.


How to reproduce:
rsync over 100Mbit ethernet like this works for me:

rsync -rav rsync://site/dir-with-1G-files . &
and then compile eg. glibc or anything that takes
20 minutes or more.
