Hi All,

I am using devstack/liberty, where all time while doing rejoinstack.sh getting error as

ERROR cinder.service [-] Manager for service cinder-volume ubuntu@lvmdriver-1 is reporting problems, not sending heartbeat. Service will appear "down".

I through ticket "https://ask.openstack.org/en/question/5423/rebooting-with-devstack/" as per that every time before rejoin will run below commands to make available to detached loops drive while restarting server

sudo losetup -f /opt/stack/data/stack-volumes-lvmdriver-1-backing-file sudo losetup -f /opt/stack/data/stack-volumes-default-backing-file

But It didn't helped out, May I know how to fix it ?
