New subject: Fw: Ceph Integration on Openstack Platform

15 Jun 2020

      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.

Do you have any of ideas about that?
