related.
This is how I found the source of the problem:

Hello,
You only need a create a pool and authentication in Ceph for cinder.
Your configuration should be like this (This is an example configuration
with Ceph Jewel and Openstack Mitaka):
[DEFAULT]
enabled_backends = ceph
[ceph]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rbd_pool = vol
Thank you everyone, I just tested and verified the ruleset and applied
it so some pools. Worked like a charm!

Thanks Jason,
I think I'm going to start with a bash script which SSH's into the machine to
check if the process has finished writing and then calls the fsfreeze as I've
got time constraints to getting this working. But I will definitely revisit
this and see if there is something I can create w
Hi,
As far as I know, this is exactly the problem why the new tunables where
introduced, If you use 3 Replicas with only 3 hosts, crush sometimes doesn't
find a solution to place all pgs.
If you are really stuck with bobtail turntables, I can think of 2 possible
workarounds:

It seems that the packages "ceph-release-*.noarch.rpm" contain a
ceph.repo pointing to the baseurl
"http://ceph.com/rpm-hammer/rhel7/$basearch"; which does not exist. It
should probably point to "http://ceph.com/rpm-hammer/el7/$basearch";.

Hi,
We are running Openstack Liberty with a Ceph Jewel backend for glance,
cinder, and nova.
Creating a new instance booting from volume works fine, but resizing this
fails with the following:

Hi!
Our little dev ceph cluster (nothing fancy; 3x1 OSD with 100GB each, 3x monitor
with radosgw) takes over 20 minutes to delete ca. 44000 small objects (<1GB in
total).
Deletion is done by listing objects in blocks of 1000 and then deleting them in
one call for each block; each deletion of 10

Hi Gaurav,
Have you distributed your Ceph authentication keys to your compute
nodes? And, do they have the correct permissions in terms of Ceph?

I'd recommend generating an UUID and use it for all your compute nodes.
This way, you can keep your configuration in libvirt constant.

Thanks for the pointer, I didn't know the answer, but now I do, and

Hi Kees,
I regenerated the UUID as per your suggestion.
Now i have same UUID in host1 and host2.
I could create volumes and attach them to existing VMs.
I could create new glance images.

There is no Ceph plugin for VMware (and I think you need at least an Enterprise

The "VMware" way to do this without the plugin would be to have a VM running on

Just for giggles I tried the rolling upgrade to 10.2.2 again today.
