Hi, I've wanted to use ceph storage as a backend for nova, glance and cinder. I've succeded to use ceph for cinder and glance but I couldn't at nova. I have seen this bug for "Stein" version ---> https://bugs.launchpad.net/nova/stein/+bug/1860990 Bug #1860990 “RBD image backend tries to flatten images even if ...” : Series stein : Bugs : OpenStack Compute (nova)<https://bugs.launchpad.net/nova/stein/+bug/1860990> bugs.launchpad.net When [DEFAULT]show_multiple_locations option is not set in glance, and both glance and nova use ceph as their backend, with properly configured accesses, nova will fail with the following exception: 2020-01-23 14:36:43.617 8647 ERROR nova.compute.manager [req-8021fd76-d5ab-4a9b-bd17-f5eb4d4faf62 0e96a04f360644818632b7e46fe8d3e7 ac01daacc7424a40b8b464a163902dcb - default default] [instance: fa9e4118-1bb1-4d52-a2e1-9f61b0e20dc6] Instance failed to spawn: rbd.InvalidArgument: [errno 22] error f... After that, I've entered the nova-compute pod and I've run below commands; apt install python-rbd apt install python3-rbd But it didn't work. I've gotten same error. A solution must be on the K8s side. error; 2020-06-15 12:34:23.617 21543 ERROR nova.compute.manager File "/var/lib/openstack/lib/python3.6/site-packages/nova/virt/libvirt/driver.py", line 1216, in _get_rbd_driver 2020-06-15 12:34:23.617 21543 ERROR nova.compute.manager rbd_user=CONF.libvirt.rbd_user) 2020-06-15 12:34:23.617 21543 ERROR nova.compute.manager File "/var/lib/openstack/lib/python3.6/site-packages/nova/virt/libvirt/storage/rbd_utils.py", line 128, in __init__ 2020-06-15 12:34:23.617 21543 ERROR nova.compute.manager raise RuntimeError(_('rbd python libraries not found')) 2020-06-15 12:34:23.617 21543 ERROR nova.compute.manager RuntimeError: rbd python libraries not found Nova compute image; [cid:e78156d8-4edf-4abd-8585-7e346fb1f879] Do you have any of ideas about that?
