创建3个卷images、volumes、instances分别对接openstack的glance、cinder、nova组件
images卷用于存放OpenStack镜像
volumes卷用于存放OpenStack硬盘
instances卷用于存放OpenStack云主机
1、 创建卷

gluster volume create images replica 3 \
controller1:
/data/brick1/image
controller2:
/data/brick1/image
compute01:
/data/brick1/image
\
controller1:
/data/brick2/image
controller2:
/data/brick2/image
compute01:
/data/brick2/image
\
controller1:
/data/brick3/image
controller2:
/data/brick3/image
compute01:
/data/brick3/image
gluster volume create volumes replica 3 \
controller1:
/data/brick1/volume
controller2:
/data/brick1/volume
compute01:
/data/brick1/volume
\
controller1:
/data/brick2/volume
controller2:
/data/brick2/volume
compute01:
/data/brick2/volume
\
controller1:
/data/brick3/volume
controller2:
/data/brick3/volume
compute01:
/data/brick3/volume
gluster volume create instances replica 3 \
controller1:
/data/brick1/instance
controller2:
/data/brick1/instance
compute01:
/data/brick1/instance
\
controller1:
/data/brick2/instance
controller2:
/data/brick2/instance
compute01:
/data/brick2/instance
\
controller1:
/data/brick3/instance
controller2:
/data/brick3/instance
compute01:
/data/brick3/instance
|
2、 启动卷
|

3
|
gluster volume start images
gluster volume start volumes
gluster volume start instances
|
3、 添加images、instances到fstab自动挂载
|

|
controller1:
/images
/var/lib/glance/images
glusterfs defaults,_netdev,backupvolfile-server=controller2,backupvolfile-server=compute01 0 0
controller1:
/instances
/var/lib/nova/instances
glusterfs defaults,_netdev,backupvolfile-server=controller2,backupvolfile-server=compute01 0 0
|
mount -a 挂载
上述挂载方式使用backupvolfile起到了高可用性，避免单点故障
nova、glance节点要挂载到instances、images的相关目录，根据实际服务部署情况调整，cinder不太一样，下边会说到。
4、 设置相关权限

chown
-R nova.nova
/var/lib/nova/instances
chown
-R glance.glance
/var/lib/glance/images
chown
-R nova:nova
/data/brick1/instance
chown
-R nova:nova
/data/brick2/instance
chown
-R nova:nova
/data/brick3/instance
chown
-R glance:glance
/data/brick1/image
chown
-R glance:glance
/data/brick2/image
chown
-R glance:glance
/data/brick3/image
chown
-R cinder:cinder
/data/brick1/volume
chown
-R cinder:cinder
/data/brick2/volume
chown
-R cinder:cinder
/data/brick3/volume
|
nova要有instance、cinder要有volume、glance要有image的读写权限，根据节点上的服务，给相应的权限。
5、 配置cinder

cp
/etc/cinder/cinder

openstack-config --
set
/etc/cinder/cinder

touch

vim
/etc/cinder/shares
.conf
#添加以下内容
controller1:
/volumes
controller2:
/volumes
compute01:
/volumes
|
#设置相关权限

|
chown
-R cinder.cinder
/etc/cinder/shares
.conf
chown
-R cinder:cinder
/var/lib/cinder/
*

6、 重启openstack相关服务
|

|
openstack-service restart nova
openstack-service restart cinder
openstack-service restart glance
|
7、 验证cinder
