Gluster Client 新增 cinder volume

1. 安裝 gluster-fuse 套件。
   

   [root@kvm4 ~]# yum install -y glusterfs-fuse
   

2. 備份 /etc/cinder/cinder.conf。
   

   [root@kvm4 ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.orig
   

3. 設定 /etc/cinder/cinder.conf。
   

   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   DEFAULT enabled_backends glusterfs,lvm
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   lvm volume_group cinder-volumes
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   lvm volume_driver cinder.volume.drivers.lvm.LVMISCSIDriver
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   lvm volume_backend_name LVM
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   glusterfs volume_driver cinder.volume.drivers.glusterfs.GlusterfsDriver
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   glusterfs glusterfs_shares_config /etc/cinder/shares.conf
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   glusterfs glusterfs_sparsed_volumes false
   [root@kvm4 ~]# openstack-config --set /etc/cinder/cinder.conf \
   glusterfs volume_backend_name RHS
   

4. 建立分享 volume 設定檔，加入 volume4。
   

   [root@kvm4 ~]# echo "kvm4.deyu.wang:volume4" >> /etc/cinder/shares.conf
   

5. 重新啟動 openstack-cinder-schduler 及 openstack-cinder-volume 服務。
   

   [root@kvm4 ~]# /etc/init.d/openstack-cinder-scheduler restart
   Stopping openstack-cinder-scheduler:               [  OK  ]
   Starting openstack-cinder-scheduler:               [  OK  ]
   [root@kvm4 ~]# /etc/init.d/openstack-cinder-volume restart
   Stopping openstack-cinder-volume:                  [  OK  ]
   Starting openstack-cinder-volume:                  [  OK  ]
   

6. 查看啟動情況，沒訊息表示啟動正常。
   

   [root@kvm4 ~]# tail /var/log/cinder/volume.log
   

7. 查看掛載狀況，volume4 已掛載。
   

   [root@kvm4 ~]# df
