Hi,
on an EL5 XEN DOM0 system I have following volume
$ df -h /srv Filesystem Size Used Avail Use% Mounted on /dev/sdc1 917G 858G 60G 94% /srv
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
what could keeping the device "busy" ... ?
__ Thanks,
LF

Run as root: # lsof +D /srv
$ fuser -m /srv <empty>
Again, run this as root. Compare (test example from my system): $ fuser -m /boot 2>/dev/null | wc 0 44 264 # fuser -m /boot 2>/dev/null | wc 0 223 1338
That's 180 processes I'd miss as an ordinary user.
$ fuser -km /srv <empty>

$ umount /srv umount: /srv: device is busy umount: /srv: device is busy
I'm sure you've checked, but where is your PWD?

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

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

I am also not sitting on the device :-)

Although the prompt is a $, I assume you're actually doing this as root?
$ umount /srv umount: /srv: device is busy umount: /srv: device is busy

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

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

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

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