[OpenAFS] umount /afs busy ?

[Jinwei Shen]

hi, 

I am using open-afs-1.1.1 with Debian potato (kernel 2.4.4) on a
laptop. (apt-get from http://www.openafs.org/dl/openafs/1.1.1)

I use /etc/init.d/openafs-client force-start to start afs, and
/etc/init.d/openafs-client force-stop to stop it. However, sometime I
can not stop it because of umount /afs busy. I tried to use two ways
to identify which process is using /afs.

1/ lsof |grep afs (lsof version 4.48).
2/ fuser -vm /afs

neither print anything. Is there a way to stop afs instead of reboot
in this case? 

Thanks!
