Bug #1852086 “etcd3 driver missing in binary images” : Bugs : kolla-ansible

Bug Description

O/S: Ubuntu 18.04
OpenStack: Stein
Deploy: Kolla-ansible with ceph
H/W: 1 deploy, 3 controller, 4 compute/storage with 7 disks for ceph

[What happened:]
After successful installation, cinder-volume and cinder-backup went down. If I restart the services using the docker restart command, there services on the horizon dashboard stays up for about 30 seconds and then goes back down.

Ceph has been deployed successfully, and Glance and Nova services that use ceph work fine.

[reproduce:] yes.

This is the effect of enabling etcd - cinder coordination backend became etcd and it seems not available in the Ubuntu images.

Since you are using ceph, and hence not need coordination, as a workaround set:
cinder_coordination_backend: ''
in globals.yml

Works fine. This was not a bug. The wrong setting was the cause. Thank you very much.

Radosław Piliszek (yoctozepto) wrote on 2019-11-15:

I am glad it helped you.

OTOH, this is a bug - we need to ship etcd support in Ubuntu cinder images since we "support" etcd for coordination.

Radosław Piliszek (yoctozepto) wrote on 2019-11-15:

It seems we don't have etcd3 in binary centos nor ubuntu images (nor debian for completeness). Hence it is broken with binary. Let's do what I planned to do - default to no coordination - less surprises.

Ok, so after a bit of discussion and a bit of investigation, I decided to fix the problem in a different way - we can include etcd3gw as etcd3 driver which seems more popular and can be included in binary builds. It also fixes the instability problems introduced by etcd3 - all the more reason to switch it.

summary:	- cinder-volume, cinder-backup service down with CEPH + etcd3 driver missing in ubuntu binary
