This patch will enable user to configure single cinder store as well as
multiple cinder stores for glance. Below are the parameters needs to be
added in local.conf.
A. For single store
USE_CINDER_FOR_GLANCE=True
B. For Multiple stores
USE_CINDER_FOR_GLANCE=True
GLANCE_ENABLE_MULTIPLE_STORES=True
CINDER_ENABLED_BACKENDS=${CINDER_ENABLED_BACKENDS:-lvm:lvmdriver-1,lvm:lvmdriver-2,nfs:nfsdriver-1,ceph:cephdriver-1}
GLANCE_CINDER_DEFAULT_BACKEND=lvmdriver-1
enable_plugin devstack-plugin-nfs https://opendev.org/openstack/devstack-plugin-nfs
enable_plugin devstack-plugin-ceph https://opendev.org/openstack/devstack-plugin-ceph
NOTE:
GLANCE_CINDER_DEFAULT_BACKEND should be one of the value from CINDER_ENABLED_BACKENDS.
If you need to configure nfs and ceph backend for cinder then you need to add respective plugins in
local.conf file.
If GLANCE_ENABLE_MULTIPLE_STORES is True then it will not configure
swift store for glance even if it is enabled in local.conf file.
