Open Stack

Hello Xin,
This error indicates that there is no volume group named "stack-volumes".
Can you verify if it exists with the command "sudo vgs"?
If does not exist, perhaps something is in the devstack logs about why it
failed to create it?

Thanks,
Avishay

Subject:	[openstack-dev] ERROR : Unable to locate Volume Group
            stack-volumes



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.

thanks
xin
