Yeah - its a bad behaviour doing tasks with a # prompt and then 
making a request in mailinglists with $ as prompt. Sorry for that.



 $ umount /srv
 umount: /srv: device is busy
 umount: /srv: device is busy
 
 
 what could keeping the device busy ... ?
 
 Is the device NFS exported?  I've seem that prevent umounting even though
 nothing shows up in the process list.



Its a local virtual device (raid controller exports it as one device).

okay - i will try this scan before booting next time.

 Again, run this as root.  Compare (test example from my system):

 That's 180 processes I'd miss as an ordinary user.


yep - all my commands were executed as root user (sorry for the $ vs. #

 $ umount /srv umount: /srv: device is busy umount: /srv: device is

 I'm sure you've checked, but where is your PWD?


I am also not sitting on the device :-)

I believe that Stephen was asking if you are exporting that filesystem 
via NFS to other systems.  Check /etc/exports.

that partition was used by virtual machines but they were all halted.

service xendomains stop

$ xm list
Name  ID Mem(MiB) VCPUs State   Time(s)
Domain-0   0 3000 2 r-695.1

$ service xend stop


nothing is using the partition
$ lsof |grep srv
empty

$ fuser -m /srv
empty

$ fuser -km /srv
empty


but i can not umount /srv

$ umount /srv
umount: /srv: device is busy
umount: /srv: device is busy

 $ umount /srv

Is the device NFS exported?  I've seem that prevent umounting even though
nothing shows up in the process list.
