##### SUMMARY
<!-- Explain the problem/feature briefly -->
Can't detach volumes created on GlusterFS primary storage from VM. Tested on two different cloudstack installations. Everything works fine with other primary storage types. The volume can be detached and removed if the VM status is stopped but not when running.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
- Create GlusterFS Primary Storage with tag
- Create Disk Offering that uses just crated GlusterFS Primary Storage's tag.
- Create Volume using just created Disk Offering
- Attach Volume to VM
- Detach Volume from VM
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
- Success detaching Volume
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
- (test-detach) Failed to detach volume test-detach from VM test-vm-for-gluster ; com.cloud.exception.InternalErrorException: disk: /mnt/b440b605-a876-35f8-be84-2b5696650654/5605035d-e060-42a6-89a1-6f9c949463fc is not attached before

@DaanHoogland this is a genuine error. i didn't find a solution even inspecting logs. I had to select another primary storage solution (NFS in my case) which works as expected.
I think it could be related to how libvirtd handles GlusterFS volumes, but I'm not expert in this. I tried to look around in libvirt/QEMU logs, but I couldn't find nothing.

@kalik1 is this a genuine error or a false positive, i.e. is the volume indeed not detached or is the error message misleading?
Also as I don´t, do you have anyway of investigating the issue?

@kalik1 , I know of no ACS installation using GlusterFS . Can you add more details if you need help. Alternatively send a mail to the users mail list.

Ok, @kalik1 I think the first thing is to look at the libvirtd project and ask around there if the issue is known.
Another thing to do is to try and dismount the volume directly in kvm/qemu/libvirtd and see if that fails in the same way (as to eliminate/determine libvirtd as the culprit indeed)
any logs could be helpful, of course but only if it contains clear error messages.
good luck and good hunt, happy to help but I am afraid that won't be much.
