We've had an lvm_type=thin for quite some time, and we've wanted to make it Cinders default for a while, but there's no clean way to migrate on upgrades. So, we have a compromise, detect if the deployment has volumes (including the thin pool). If there are no LVs or if the thin pool exists, use thin. Otherwise, use the old thick lvm-default. This patch makes the default setting "auto" instead of "default" (which is actually thick). DocImpact: Need to update docs to reflect the default setting for new deployments is auto (thin) Change-Id: If25e814eb6282fef9a1dd30d17c80eab6860e275

Modify default lvm_type setting from thick to auto. This will result in
|
|
Cinder preferring thin on init, if there are no LV's in the VG it will
|
|
create a thin-pool and use thin. If there are LV's and no thin-pool
|
|
it will continue using thick.
