Ready LVM Volume Provider
Components Cinder Volume management is responsible for the real volume provider.
Cinder supports multiple volume provider, LVM is the default volume provider.
After Devstack installation, / etc / cinder / cinder already configured LVM,
As shown below:
The above configuration defines the volume provider called "lvmdriver-1" is also referred to as back-end.
Which driver is LVM, LVM volume group called the "stack-volumes-lvmdriver-1".
And it does not automatically create a volume group when Devstack installation, so we need to be created manually.
The following steps demonstrate the creation VG "stack-volumes-lvmdriver-1" on / dev / sdb:
1, first create physical volume / dev / sdb
2, Linux lvm the default configuration does not allow to create PV on / dev / sdb, sdb need to be added to the filter /etc/lvm.conf in.
3, and then create VG stack-volumes-lvmdriver-1
Open the Web GUI, you can see OpenStack has been created Volume Type "lvmdriver-1"
Extra Specs volume_backend_name which is lvmdriver-1
