Hi, I've checked the log and the issue you're having is probably this bug: https://bugs.launchpad.net/cinder/+bug/1931004 The fix is currently under review upstream. A quick solution to this issue is to set the rbd_store_chunk_size to 8 in cinder.conf which will make the stripe size of cinder same as glance.

Hi,
As you might already know if you read this mailing list, I've been
trying to push Kolla into production for a while. This issue however
might be more Glance and Cinder related than Kolla. We're trying to
provision an Openstack Wallaby cluster on Ubuntu using Kolla and Ceph
pacific. The issue I now have is that, if I try to provision a Ceph
volume from an image stored in Ceph, I get the following error :
By looking around a bit, I figured out that this is linked to the
following mailing list email :
https://www.spinics.net/lists/ceph-users/msg66016.html
Ceph copy on write cloning breaking because Cinder can't work
ifshow_image_direct_url is set to true is a pretty big issue, I believe.
It's possible that this has been talked about before, but there's no
other trace I could find outside of that Ceph mailing list email.
Additionally, in Kolla, setting show_image_direct_url to false doesn't
solve this issue because by default, Kolla appears to also set
show_multiple_locations to true. By setting show_multiple_locations to
false through a custom configuration, I am able to create volumes from
glance Ceph images again (images have to be re-uploaded for this to work
though). Of course, these volumes are not created through copy-on-write,
because that's broken.
I couldn't find any bug report pertaining to these issues. If they are
not known, then I would be happy to make a bug report. I would just like
to verify if this is all already known or not.
