Hi,
we want to use a Ceph cluster as the main storage for our oVirt 4.1.x
datacenter. We successfully tested using librbd1-12.2.1-0.el7 package
from Ceph repos instead of the standard librbd1-0.94.5-2.el7 from CentOS
7 in an oVirt virtualization node. Are there any caveats when doing so?
Will this work in oVirt 4.2?
thx
matthias

Hello Matthias. Can I ask separate question?
At this time we atoVirt 4.1.3.5 and Ceph Cluster at 11.2.0 (Kraken).In
few weeks I planned to expand the cluster and I would like to upgrade to
Ceph 12 (Luminous), for bluestore support.
So my question is:have you tested oVirt with Ceph 12?
Thanks.

Hi Konstantin,
yes, we have a Ceph 12 Cluster and are using librbd1-12.2.1 on oVirt
Hypervisor Hosts, which we're installed with CentOS 7 and Ceph upstream
repos, not oVirt Node (for this exact purpose). Since
/usr/lib64/libvirt/storage-backend/libvirt_storage_backend_rbd.so is
using /lib64/librbd.so.1 our VMs with disks from Cinder storage domain
are using Ceph 12 all the way.
Are you also using a newer librbd1?
Regards
Matthias

On oVirt Hypervisor hosts
we use librbd1-0.94.5-1.el7.x86_64

Our OpenStack cinder is
openstack-cinder-10.0.0-1.el7.noarch with
librbd1-10.2.3-0.el7.x86_64
What version of Cinder I should have for work with Ceph 12? Or just
upgrade python-rbd/librados/librbd1/etc.

Not for now as you can
see. I was open "ovirt-users" for my questions
about Ceph 12 and see your fresh message. I think you first who used
Ceph 12 with oVirt.

I'll talk to my colleague, who is the Ceph expert, about this tomorrow.

Our OpenStack cinder is openstack-cinder-10.0.0-1.el7.noarch with
librbd1-10.2.3-0.el7.x86_64
we're also using cinder from openstack ocata release.
the point is
a) we didn't upgrade, but started from scratch with ceph 12
b) we didn't test all of the new features in ceph 12 (eg. EC pools for
RBD devices) in connection with cinder yet

Thanks. We use EC pools with replication pull cache - only one way to
use EC with rbd, before Ceph 12.
We are half year on Ceph with oVirt in production. The best storage
experience, the only thing you can find fault this is impossible to move
images between pools. Only manually migration with qemu-img/rados or
cp/rsync inside VM.

We are live on librbd1-12.2.1 for a
week. All works okay.
I was upgraded ceph from 11.2.0 to 11.2.1. Not Luminous, because seems
12.2.1 is stable only when cluster started from Luminous
(http://lists.ceph.com/pipermail/ceph-users-ceph.com/2017-November/022522....).
