Volumes are being created just fine in the "volumes" pool but they are not
bootable
Also, ephemeral instances are working fine ( disks are being created on the
dedicated ceph pool "instances')
That sounds like cinder is missing something regarding glance. So the
instance is listed as "ACTIVE" but what do you see on the instance?
Does it show something like "no bootable device" or a similar message?
I don't have Rocky and Mimic, so there might be something else. To
rule out the qemu layer you could try to launch from a volume with kvm
like suggested in [1].
Is this a new setup or an upgraded environment? If it's an existing
environment, did it ever work with volumes? Do you use cephx and have
you setup rbd_secret on your compute node(s)?

Eugen

Access for cinder user from compute node is fine
[root@ops-ctrl-new ~(devops)]# rbd --user cinder -k
/etc/ceph/ceph.client.cinder.keyring -p volumes ls
volume-04c3d1a6-e4f0-40bf-a257-0d76c2a6e337

Hi,
can you explain more detailed what exactly goes wrong?
In many cases it's an authentication error, can you check if your
specified user is allowed to create volumes in the respective pool?
You could try something like this (from compute node):
rbd --user <OPENSTACK_USER> -k
/etc/ceph/ceph.client.OPENSTACK_USER.keyring -p <POOL> ls
additionally, try to create an image in that pool. If that works, you
should double check the credentials you created within ceph and
compare them to the credentials in your openstack configs.
That would be my first guess.

Eugen
