Creating a Volume

Modify cinde.conf – add new volume group with options (below)

Configure multiple-storage back ends

default_volume_type = local_zfs
enabled_backends = local_zfs,zfssa

[zfs_local]
zfs_volume_base=rpool/cinder
volume_driver=cinder.volume.drivers.solaris.zfs.ZFSVolumeDriver
volume_backend_name = zfs_local

[zfssa]
iscsi_helper=tgtadm
volume_backend_name = zfssa
volume_driver = cinder.volume.drivers.zfssa.zfssaiscsi.ZFSSAISCSIDriver
san_ip = 10.10.0.238
san_login = zfs_cinder
san_password = password
zfssa_pool = HP-pool
zfssa_project = openstack
zfssa_initiator_group = default
zfssa_target_portal = 10.10.0.238:3260
zfssa_target_interfaces = vnic8
zfssa_target_group=os-tgt-gpt
zfssa_lun_volblocksize=8k
zfssa_lun_compression=lzjb
zfssa_lun_logbias=latency
zfssa_initiator = iqn.1986-03.com.sun:02:1223de4b-21fc-6b74-f16a-ba9d73ad054c
zfssa_rest_timeout = 700

Restart cinder volume

svcadm restart svc:/application/openstack/cinder/cinder-volume:setup svc:/application/openstack/cinder/cinder-volume:default

From Horizon, as the admin user, create a zfssa volume type: name zfssa and a volume type zfs_local

Then assoitae the volumes with the volume group

Note: if you have two backends with the same backend name it will be used in round robin

cinder type-key zfs_local set volume_backend_name=zfs_local

cinder type-key zfssa set volume_backend_name=zfssa
