Cannot unmount an fs during shutdown... why ?

[TSch]

Hello everybody,

whenever we're shutting down our system, we get something like the following message:

Cannot Unmount /dev/u1
Device is busy

What can cause this behaviour ?
u1 is a newly created file system with no data in it.
Fact is, that it's the home directory of an also newly created user, which is not in use right now...

And ideas ?

Thanks in advance !

Regards
Thomas

try

fuser /dev/u1

and look at the pid it gives.

if you are sure that its newly created file system.

then simply user #fuser -k <fsname>

any way make sure by checking with #fuser <fsname> it will give you the pid of the process which is using the filesystem.

i hope it will help you.
