Hi Oliver,

Looking at the output - the problem is with connection to etcd coordination backend.

Best regards, Michal

Hi,

after replacing my control nodes with new nodes (all bare-metal) somehow the cinder containers are no longer starting.

I checked the logs on one of the control nodes and I see this in the api-eror.log:

All other containers are working just fine. Even the cinder_scheduler container works fine.

So far I have tried the following:

remove the cinder containers including its volume from one control node

mariadb_recovery

Reboot all control nodes.

kolla-ansible reconfigure --tags cinder,nova

Any help is highly appreciated.

Cheers,

Oliver
