假如今天我們今天要使用lvm及ceph當作我們的cinder storage，在修改cinder.conf之前須做一些前置設定 ，如lvm的套件或是ceph的相關帳號權限設定， 可參考 利用opensource 安裝openstack 結合 linuxbridge與vxlan– All In One (kilo) 如何使用ceph當作cinder backend storage 在cinder.conf中 [DEFAULT] enabled_backends = rbd,lvm [lvm] volume_backend_name = lvm volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = tgtadm [rbd] volume_backend_name = rbd volume_driver = cinder.volume.drivers.rbd.RBDDriver rbd_pool = volumes rbd_ceph_conf = /etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot = false rbd_max_clone_depth = 5 rbd_store_chunk_size = 4 rados_connect_timeout = -1 glance_api_version = 2 rbd_user = cinder rbd_secret_uuid = 457eb676-33da-42ec-9a8c-9293d545c337 然後利用cinder cmd新增type # 建立type為lvm跟ceph $ cinder type-create lvm $ cinder type-create ceph # 設定lvm type的backend為lvm $ cinder type-key lvm set volume_backend_name=lvm # 設定ceph type的bac...

在ceph node底下 # 建立ceph pool 給cinder使用,pool名稱為volumes $ sudo ceph osd pool create volumes 128 建立一個user為client.cinder並對pool volumes相關權限設定,產生一個keyring file $ sudo ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms, allow rx pool=images' -o /etc/ceph/ceph.client.cinder.keyring # 複製ceph.conf與cinder.keyring到openstack controller上 $ scp /etc/ceph/ceph.conf root@ openstack node ip :/etc/ceph $ scp /etc/ceph/ceph.client.glance.keyring root@ openstack node ip :/etc/ceph # 複製client.cinder的key複製到controller /tmp/ client.cinder.key 上 $ ceph auth get-key client.cinder | ssh openstack node ip tee /tmp/client.cinder.key 添加一个secret key到libvirt $ uuidgen d65bc749-e160-44d3-a903-9c50291b4293 $ cat > secret.xml <<EOF <secret ephemeral='no' private='no'> <uuid> d65bc749-e160-44d3-a903-9c50291b4293 </uuid> ...
