cinder-lvm后端

建立物理卷及卷组cinder-volumes

pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb

修改kolla-ansible全局配置

vi /etc/kola/globals.yml
......
enable_cinder: "yes"
enable_cinder_backend_iscsi: "yes"
enable_cinder_backend_lvm:: "yes"
cinder_volume_group: "cinder-volumes" #此处创建的vg名称
......

部署

kolla-ansible deploy -i multinode -t haproxy,cinder,iscsi,horizon

cinder-ceph后端

存储节点&计算节点安装ceph客户端软件

yum install -y ceph-common

建立ceph池

ceph osd pool create images 32 32
ceph osd pool create volumes 32 32
ceph osd pool create backups 32 32
ceph osd pool create vms 32 32
ceph osd pool ls

建立ceph用户分配权限

ceph auth list
ceph auth get client.admin

# glance
ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rdb_children, allow rwx pool=images' -o ~/ceph.client.glance.keyring
ceph auth get-or-create client.glance mon 'profile rbd' osd 'profile rbd pool=images' mgr 'profile rbd pool=images'
ceph auth get-or-create client.glance -o ~/ceph.client.glance.keyring

# cinder
ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rdb_children, allow rwx pool=volumes' -o ~/ceph.client.cinder.keyring
ceph auth get-or-create client.cinder mon 'profile rbd' osd 'profile rbd pool=volumes, profile rbd pool=vms, profile rbd-read-only pool=images' mgr 'profile rbd pool=volumes, profile rbd pool=vms'
ceph auth get-or-create client.cinder -o ~/ceph.client.cinder.keyring

# cinder-backup
ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rdb_children, allow rwx pool=backups' -o ~/ceph.client.cinder-backup.keyring
ceph auth get-or-create client.cinder-backup mon 'profile rbd' osd 'profile rbd pool=backups' mgr 'profile rbd pool=backups'
ceph auth get-or-create client.cinder-backup -o ~/ceph.client.cinder-backup.keyring

# nova
ceph auth get-or-create client.nova mon 'allow r' osd 'allow class-read object_prefix rdb_children, allow rwx pool=vms' -o /etc/ceph/ceph.client.nova.keyring
ceph auth get-or-create client.nova mon 'profile rbd' osd 'profile rbd pool=volumes, profile rbd pool=vms, profile rbd-read-only pool=images' mgr 'profile rbd pool=volumes, profile rbd pool=vms'
ceph auth get-or-create client.nova -o /etc/ceph/ceph.client.nova.keyring

修改kolla-ansible全局配置

enable_cinder: "yes"
enable_grafana: "yes"
 
glance_backend_ceph: "yes"
