[Openstack] [Cinder] Help needed recovering cinder volumes


What kind of device is backing your LVM PVs? Is it a disk partition or a
loopback device? If it's the latter, is it activated?

What does "pvs" returns?

If vgscan won't show any logical volumes, you're probably looking at the
wrong device or the LVs were removed. If this happened, you may be able to
rebuild LVM from archive, depending on your LVM configuration.

I don't have detailed steps to provide, but I'm sure there are several
articles about this out there.

PS: Sorry for top posting. Gmail app will mess with everything if I try to
answer inline.
