Hi all,

For a long time, I have the problem that after shutting down AFS under
RedHat 7.1, the partition on which the AFS cache resides can not be
unmounted:

[root@elliot /root]# cat /etc/fstab
LABEL=/                 /                       ext2    defaults
1 1
LABEL=/.afs_cache       /.afs_cache             ext2    defaults
1 2
LABEL=/local            /local                  ext2    defaults
1 2
LABEL=/tmp              /tmp                    ext2    defaults
1 2
LABEL=/usr              /usr                    ext2    defaults
1 2
LABEL=/var              /var                    ext2    defaults
1 2
none                    /proc                   proc    defaults
0 0
none                    /dev/pts                devpts  gid=5,mode=620
0 0
/dev/hda5               swap                    swap    defaults
0 0

[root@elliot /root]# umount /.afs_cache
[root@elliot /root]# mount /.afs_cache
[root@elliot /root]# /etc/rc.d/init.d/afs start

[root@elliot /root]# /etc/rc.d/init.d/afs stop
Stopping AFS services.....
inetd.afs: no process killed
[root@elliot /root]# umount /.afs_cache
umount: /.afs_cache: device is busy

The content of cacheinfo is:
[root@elliot /root]# cat /usr/vice/etc/cacheinfo
/afs:/.afs_cache:90000
The partition size of /.afs_cache is 100MB.

There are no afsd processes running after the shutdown. The kernel
module is properly unloaded. Anyone has an idea why the system thinks
that the partition is still in use? It doesn`t help to wait, btw. The
partition can`t be unmountet after 15' or so either.

Thanks for your help.

Regards,
    Marc
