Hi, If we use devstack to start c-vol progress as the following and use multi-backend: cinder-volume --config-file=/etc/cinder/cinder.conf There will be several cinder-volume progress loged into just one cinder-volume.log, * and it is difficult to distinguish<app:ds:distinguish> which log message is belonged to which cinder-volume progress. So can I add progress id info into cinder-volume log? Liu -------------- next part -------------- An HTML attachment was scrubbed...
