Hi all, I am using devstack and sometimes when i do a ./unstack.sh and then ./stack.sh, there is a Unable to locate Volume Group stack-volumes ERROR as followed. Does anyone know what causes the error and how to solve the issue? Before i do the ./unstack.sh and redo ./stack.sh. Everything looks good.
