NFS unmount problem

Werner Placke — Wed, 01 Aug 2001 07:38:11 GMT

hallo admin's
on my nfs-client (hp-ux 10.20) are three directories mounted on a nfs-server (hp-ux 11.0). if i try "umount /sapmnt/PUG/exe", i get a messages : umount: cannot unmount /sapmnt/PUG/exe : Device busy

the command fuser -u /sapmnt/PUG/exe
shows no aktive process on this directory.
What is the problem?
Thanks!!

Werner

HI,

try fuser -cu /sapmnt/PUG/exe or fuser -cuk /sapmnt/PUG/exe if you don't care about the users.

If you still have a problem i would reconmend using lsof to check for open files.

BTW: hope its not yourselfe "standing" in this mountpoint.

Hope this helps

Regards Stefan

You can also do an fuser /dev/vgXX/lvolX to get any associated processes against the logical devices. I believe all the switches will work for this as well.
