Hi Gorka,

Yeah, we are using active-active cinder deployment.

Hi,

Error seems to be happening acquiring a lock with the Redis driver in
Tooz, so it must be configured to be used by Cinder as the DLM.

This is only necessary when the Cinder Volume service is configured as
Active-Active.  Are you running the volume service as Active-Active?

If you are not you should be able to fix the issue by commenting the
backend_url configuration option in the [coordination] section of the
cinder.conf file.

Cheers,
Gorka.
