We’re running OpenNebula with a CEPH datastore. Currently we’re trying to attach new disks (raw format) but everytime we we get an qemu error:

Hello,  
If you mean attach Volatile disk - change DISK\_TYPE in datastore attributes. You need change FILE to RBD.

P.S. Thanks @heathen for help!

It does not matter. It was a private discussion. Stop flooding

Hi, @marcindulak!

We have a private messages discussion: Anton has asked me about the same problem and I advised him to change DISK\_TYPE property of the ceph system datastore from FILE to RBD. In this case it’s possible to have volatile disks on the rbd ceph pool.

Hi @UAnton!

Thanks for your help.

The image datastore is already DISK\_TYPE RBD  
Do I have to set this attribute also in the system datastore?

Hi, Dominique!

Please, list all of your datastores with `onedatastore list` and then fire `onedatastore show <ID>` with each datastore ID you have and then paste here the output. You may want to remove host\secret information.

BR,  
Vladimir

This is pretty weird. Would you mind to paste `/var/lib/one//datastores/100/21404/disk.2.attach` content as well?

By the way, if you’ve made a clean ONE 5.4 install oneadmin:onegroup should has uid\gid 9869 (I see that your’s is uid:1001, gid:1001). Please check ONE processes and /var/lib/one/datastores/100/21404/\* permissions.

Is error the same after you changed DISK\_TYPE to RBD? Did you restart opennebula service (it should work even ?

User permissions are correct

Yes the same error as before.  
No I didn’t restart the opennebula service =\> Will do this during this day.

Thank you very much!

That’s pretty weird, it shouldn’t be like that. It should point to RBD image on the ceph pool if your disk type is RBD and storage driver is ceph.

I’ve made a test. I changed DISK\_TYPE of my system ds to FILE and tried to attach a volatile FS (swap should be the same) disk. Got the same error as you (see below). Then I changed DISK\_TYPE back to RBD and repeat attempt. This time successful. The only difference between your’s and my DS properties is ALLOW\_ORPHANS (I’ve set it to YES), but it shouldn’t have any influence.

I didn’t even restart ONE.

I would strongly advice you to check again that the DS 100 `DISK_TYPE` value is `RBD` (without any hidden characters, spaces and so on).

I managed to add a voltaile disk. But only if the VM was deployed on a specific server.  
We currently have 5 servers with 2 different OS states (2 are newer than the other 3)

So probably it’s caused by this.  
Also already created images couldn’t be attached. But there I assume it’s a Parameter problem…

=\> I will dig into it

Thank you very much @heathen for your help!

Sorry to “reopen” this issue  
But I tried to add already created images, so which are already shown as one images, and I get the following error:

```

```

It now is a different error, probably I’m missing something

Thanks for your help

I’m still getting this error from qemu, which I’m not able to resolve

Any help?

I found a bug but it seems to be related to rados block and it is quite old so not sure if this is still relevant - [https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1495895](https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1495895)

Any one having issues with Ubuntu16.04 + ONE while adding virtio disk?

Also if anyone could suggest if Centos7 KVM Packages are much stable or are they having such same issues?

Regards  
Kiran R

Haven’t been here for a while…

You definitely have configuration issues. Please be sure you have the latest OpenNebula, and force driver sync between hosts with (from your ONE controller): `onehost sync --force`.
