Hello,
I am having an issue with reiser4. I am wondering if it is a known issue
for reiser4 or I have missed something along the path.
#cat /etc/redhat-release
Red Hat Enterprise Linux ES release 3 (Taroon Update 5)
Downloaded 2.6.12 vanila kernel, applied mm2 patch (2.6.12-mm2) and then
aapplied reiser4 patch downloaded from namesys for 2.6.12-mm2
(ftp://ftp.namesys.com/pub/reiser4-for-2.6/2.6.12-mm2/reiser4-vfs-3.patch).
Kernel compiles and boots ok.
Compiled libaal-1.0.5 and reiser4progs-1.0.5 with ./configure, make and
make install.
Created reiser4 fs on my disk (/usr/local/sbin/mkfs.reiser4 /dev/sda5)
Mounted the partition (/dev/sda5 /test
reiser4 defaults 1 2)
"dmesg | grep reiser" shows: loading reiser4 bitmap......done (181
jiffies)
But when I try to write big amount of data on that partition the process
hangs and goes to uninterruptible sleep (D) state.
the PS output shows:
root 2375 2.7 0.0 3828 692 pts/1 D 23:21 0:15 cp -i -r
/usr .
I can easily simulate it with bonnie++
bonnie++ -u user:user -d /test -s 4096m -m hudson -n 32:100000:16:256 -b -q
I just tried that on 2.6.12-mm2 +
ftp://ftp.namesys.com/pub/reiser4-for-2.6/2.6.12-mm2/reiser4-vfs-3.patch.
And I am afraid I was not able to reproduce the problem:

can you please provide more information about your environment: amount of ram,
SMP or UP, etc.
