Objet: Re: [PVE-User] Error deleting Ceph volume from KVM
virtual machine<br>

Hi Greg,<br>
<br>
You should always stop a VM to effectively remove a hard
disk: the running VM doesn't free it until it is
stopped. You can make changes in configured harddisks in
PVE GUI but they won't be activated until next
stop/start (reboot doesn't work AFAIK).<br>
<br>
That said, the remove error could be because of a
timeout deleting the somewhat big disk.<br>
<br>
Cheers<br>

I have a 1TB RBD volume attached to a KVM virtual
machine. Removing the volume from this machine was
somewhat problematic.<br>
<br>
<br>
While the machine is running:<br>
<br>
<br>
I selected the disk and clicked Remove. This cause the
disk to appear as 'unused0' which mapped to the Ceph RBD
volume.<br>
<br>
<br>
I then highlighted 'unused0' and clicked Remove again.<br>
<br>
<br>
I got three errors:<br>
One was a timeout error attempting to get flock the VM's
lock file (/var/lock/qemu-server/lock-400.conf).<br>
Another was a connection timeout error.<br>
Another was an internal server error.<br>
<br>
<br>
I was unable to find any logs specifying the exact
nature of any of these errors. pvedaemon and pveproxy
both simply logged the request.<br>
<br>
<br>
I tried deleting the disk from Ceph directly which is
when I discovered the watcher on the rbd_header object.
I verified that it was the KVM process that held the
lock on the RBD volume and shutdown the VM.<br>
<br>
<br>
While the machine is not running:<br>
<br>
<br>
After selecting the 'unused0' disk and clicking Remove
the web interface froze for some time, and then finally
came back with an Internal Server Error.<br>
<br>
<br>
The volume was no longer present in the web interface,
and I confirmed both that the volume was no longer
listed in rbd -p volumes ls -- as well as inspecting
attempting to inspect all of the objects that used to
make up the volume (rbd.stat returned an exception
saying that the file wasn't found--confirming the
volume's completed deletion).<br>
<br>
<br>
I am running PVE 3.1-24/060bd5a6 with the 2.6.32 kernel.<br>
<br>
<br>
Is this a known issue? Has this been fixed in later
versions of Proxmox? Should I file a new bug? Is there
any additional information I should attempt to gather
before filing?<br>
<br>
<br>
Thanks!<br>
