Configure the RPC Response Timeout in Cinder

You can change the Cinder RPC response timeout for all hosts using a helm override.

Procedure

1. Create the Cinder overrides files.

   ~(keystone_admin)]$ cat <<EOF > ~/cinder-overrides.yaml
   conf:
     cinder:
       DEFAULT:
         rpc_response_timeout: 30
   EOF
   

2. Update the Cinder overrides.

   ~(keystone_admin)]$ system helm-override-update --values /home/sysadmin/cinder-overrides.yaml stx-openstack cinder openstack --reuse-values

3. Confirm that the user_override lists the correct live migration completion timeout.

   ~(keystone_admin)$ system helm-override-show stx-openstack nova openstack

   The output should include the following:

   rpc_response_timepout: 30
   

4. Update stx-openstack to apply the update.

   ~(keystone_admin)]$ system application-apply stx-openstack

5. Confirm that the update has applied successfully.

   ~(keystone_admin)]$ kubectl exec -n openstack <cinder-volume-pod-name> -- grep rpc_response_timeout /etc/cinder/cinder.conf
