創建3個卷p_w_picpaths、volumes、instances分別對接openstack的glance、cinder、nova組件
p_w_picpaths卷用於存放OpenStack鏡像
volumes卷用於存放OpenStack硬盤
instances卷用於存放OpenStack雲主機
1、 創建卷
gluster volume create p_w_picpaths replica 3 \ controller1:/data/brick1/p_w_picpath controller2:/data/brick1/p_w_picpath compute01:/data/brick1/p_w_picpath \ controller1:/data/brick2/p_w_picpath controller2:/data/brick2/p_w_picpath compute01:/data/brick2/p_w_picpath \ controller1:/data/brick3/p_w_picpath controller2:/data/brick3/p_w_picpath compute01:/data/brick3/p_w_picpath 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、 啓動卷
gluster volume start p_w_picpaths gluster volume start volumes gluster volume start instances
3、 添加p_w_picpaths、instances到fstab自動掛載
controller1:/p_w_picpaths /var/lib/glance/p_w_picpaths 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 掛載
上述掛載方式使用backupvolfile起到了高可用性，避免單點故障
nova、glance節點要掛載到instances、p_w_picpaths的相關目錄，根據實際服務部署情況調整，cinder不太一樣，下邊會說到。
4、 設置相關權限
chown -R nova.nova /var/lib/nova/instances chown -R glance.glance/var/lib/glance/p_w_picpaths 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/p_w_picpath chown -R glance:glance /data/brick2/p_w_picpath chown -R glance:glance /data/brick3/p_w_picpath 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p_w_picpath的讀寫權限，根據節點上的服務，給相應的權限。
5、 配置cinder
cp /etc/cinder/cinder.conf{,.bak}
openstack-config --set/etc/cinder/cinder.conf DEFAULT volume_drivercinder.volume.drivers.glusterfs.GlusterfsDriver
openstack-config --set/etc/cinder/cinder.conf DEFAULT glusterfs_shares_config /etc/cinder/shares.conf
openstack-config --set /etc/cinder/cinder.confDEFAULT glusterfs_mount_point_base /var/lib/cinder/volumestouch /etc/cinder/shares.conf vim /etc/cinder/shares.conf #添加以下內容 controller1:/volumes controller2:/volumes compute01:/volumes
#設置相關權限
chown -R cinder.cinder/etc/cinder/shares.conf chown -R cinder:cinder /var/lib/cinder/*
6、 重啓openstack相關服務
openstack-service restart nova openstack-service restart cinder openstack-service restart glance
7、 驗證cinder
