I am newbie to openstack.I started working on cloudlets,an openstack extension project. When I tried to execute ./rejoin-stack.sh I experienced an error as follows.

WARNING cinder.volume.manager [req-857e6c72-9d99-4dec-8a41-016ebe935b53 None None] Unable to update stats, LVMVolumeDriver -3.0.0 (config name lvmdriver-1) driver is uninitialized.

In fact I followed the instruction given in this link(https://github.com/cmusatyalab/elijah-openstack) to install openstack using devstack.

Please find the screenshot in this link(https://s11.postimg.org/ynlrjcij7/issue.png) since I am not able to attach image here. I have tried many solutions related to this question.But nothing has worked out. Please help me as I have been trying to fix the problem for the last three days.

In my opinion, devstack is not made for rebooting. rejoin-stack might work, but then it might not.

Devstack simulates the LVM physical volume with a file. The losetup command is used to add this file to the system as a block device. In my experience, rejoin-stack doesn't always re-run losetup.

My recommendation is to find out if a physical volume is present (pvs command). If not, grep the stack.sh log file for losetup, then run that losetup command. This may bring your devstack back to life.
