The default volume back-end uses local volumes managed by LVM.

This driver supports different transport protocols to attach volumes, currently ISCSI and ISER.

Set the following in your cinder.conf, and use the following options to configure for ISCSI transport:

volume_driver = cinder.volume.drivers.lvm.LVMISCSIDriver

and for the iSER transport:

volume_driver = cinder.volume.drivers.lvm.LVMISERDriver

Table 1.13. Description of configuration options for lvm
Configuration option = Default value Description
lvm_mirrors = 0 (IntOpt) If set, create lvms with multiple mirrors. Note that this requires lvm_mirrors + 2 pvs with available space
lvm_type = default (StrOpt) Type of LVM volumes to deploy; (default or thin)
volume_group = cinder-volumes (StrOpt) Name for the VG that will contain exported volumes
