Hi,
I can't umount a device even I've killed all related processes:
% umount /mnt/mpoint
umount: /mnt/mpoint: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
It can be busy simply because you are there:
% fuser -vm /mnt/mpoint
USER PID ACCESS COMMAND
/mnt/mpoint: root kernel mount /mnt/mpoint
root kernel knfsd /mnt/mpoint
I.e., there is no processes associated with the mount point any more,
but I still can't umount the device. Moreover:
$ ps -eaf | grep knfs[d] || echo no found
no found
I.e., there isn't such task as knfsd in ps list. Why is that?
Is there any way that I can kill all those kernel processes associated
with the mount?
have you tried to force the umount ?
hth,
Jerome
Thanks
