Subject2.4.17rc1 reiserfs/aacraid

hi-

with the above combination, i'm experiencing some strange behavior. i
have the following layout:

root@mail:/home/djk > df -T
Filesystem Type 1k-blocks Used Available Use% Mounted on
/dev/sda5 ext2 7566400 77008 7105040 2% /
/dev/sda1 ext2 54416 5750 45857 12% /boot
/dev/sdb6 reiserfs 8329408 200324 8129084 3% /opt
/dev/sdb5 reiserfs 9437828 1162232 8275596 13% /usr
/dev/sda7 reiserfs 9253120 112272 9140848 2% /var
shmfs shm 127552 0 127552 0% /dev/shm

everything you see is mounted at boot, with the 3 resiserfs partitions
being mounted with a standard suse 7.2 boot (/etc/init.d/boot):

mount -av -t nonfs,noproc,nodevpts

they system comes up ok, but i'm unable to unmount any of the reiserfs
partitions:

root@mail:/home/djk > umount -f /opt
umount2: Device or resource busy
umount: /opt: device is busy

what's weird is that it looks like the kernel is stuck on the mount of the
partition:

root@mail:/home/djk > fuser -v /opt

USER PID ACCESS COMMAND
/opt root kernel mount /opt


same thing for the other two reiserfs partitions.

if i remove any of the resier partitions from /etc/fstab, i'm able to
mount them and umount them without a problem once the system is up.

so, on first glance, there appears to be some type of weird interaction
between the new aacraid code and reiser.

thanks-

dan
