Before proceeding for running the script please associate the vg file with a loop device with following command with root losetup /dev/loop2 /opt/stack/data/stack-volumes-backing-file Please use rejoin-stack.sh script located at your devstack installation directory or /opt/stack/devstack Best Regards, Swapnil Kulkarni swapnilkulkarni2...@gmail.com On Wed, Aug 21, 2013 at 12:37 PM, Batsayan Das <batsayan....@tcs.com> wrote: Hi, I launch the openstack by running stack.sh as mentioned in http://devstack.org/guides/single-machine.html I created some images and instances in devstack using dashboard. When I reboot Host machine and run stack.sh again, those images and instance got lost, and I am not able to see those images and instances that I already created using dashboard. My question is 1. Is this what is expected from host reboot? 2. What I need to do to retain images and instances between multiple host reboots. The thread http://www.mail-archive.com/openstack@lists.launchpad.net/msg08453.html says to use the switch --start_guests_on_host_boot --resume_guests_state_on_host_boot. I am not sure how I should use these , which config files should have those switched enabled when I launch the devstack by simply running stack.sh I guess I need to pass some parameters or need to do **something** before running to stack.sh so that it does not destroy already crested instances and images. As I understand stack.sh reinitialize all the stuffs Looking for any help.
