openstack ocata中已经将cinder的glusterfs驱动移除，不再支持glusterfs
一、搭建gluster
1、节点准备
| hostname | ip | 数据盘vdb |
| g0 | 192.168.10.10 | 10G |
| g1 | 192.168.10.11 | 10G |
| g2 | 192.168.10.12 | 10G |
2、安装glusterfs
yum install centos-release-gluster310yum install glusterfs-server
3、创建glusterfs，登录g0
gluster peer probe g1gluster peer probe g2
4、对vdb分区
parted /dev/vdb -s -- mklabel gpt mkpart glusterfs 1 -1mkfs.xfs -f /dev/vdb1
5、挂载vdb
mkdir /datacat /srv/salt/mkfstab.sh#!/bin/bashuuid=`blkid /dev/vdb1 | awk -F' ' '{print $2}' | awk -F'=' '{print $2}' | sed s/\"//g`cat < > /etc/fstabUUID=${uuid} /data xfs defaults 0 0EOFsalt-ssh -i '*' cp.get_file salt://mkfstab.sh /tmp/mkfstab.shsalt-ssh -i '*' cmd.run 'chmod +x /tmp/mkfstab.sh'salt-ssh -i '*' cmd.run '/tmp/mkfstab.sh'salt-ssh -i '*' cmd.run 'mount -a'salt-ssh -i '*' cmd.run 'mkdir /data/fs' 6、创建卷
gluster volume create vol0 replica 3 g0:/data/fs g1:/data/fs g2:/data/fsgluster volume start vol0
7、mount.glusterfs 读取多少配置
以下引用自：
gluster 的提供option叫backup-volfile-server和backup-volfile-servers，达到挂载时候可以指定多个读取卷配置服务器。
使用方式如下：mount -t glusterfs -o backup-volfile-server=gluster2 gluster1:/volume /mntmount -t glusterfs -o backup-volfile-servers=gluster2:gluster3:gluster4 gluster1:/volume /mnt
二、配置glusterfs作为cinder后端
1、节点准备
| host | |
| newton | 使用packstack单节点安装newton |
| cinder-volume | 安装cinder-volume配置glusterfs |
2、安装openstack
通过packstack在newton节上安装openstack newton版本，过程略
3、配置glusterfs作为cinder后端
3.1、安装软件包
yum install centos-release-gluster310yum install openstack-cinder python2-keystonemiddleware python-crypto glusterfs-fuse
3.2、配置cinder
3.2.1、从newton节点上复制cinder.conf到cinder-volume节点，然后进行编辑
[DEFAULT]...enabled_backends = glusterfs...[glusterfs]volume_driver = cinder.volume.drivers.glusterfs.GlusterfsDriverglusterfs_shares_config = /etc/cinder/glusterfs_sharesvolume_backend_name=glusterfs
3.2.2、编辑/etc/cinder/glusterfs_shares
g0:/vol0g1:/vol0g2:/vol0
3.2.3、启动cinder-volume节点上的cinder-volume
systemctl enable openstack-cinder-volumesystemctl start openstack-cinder-volume
4、在nova compute节点上安装mount.glusterfs
yum install centos-release-gluster310yum install glusterfs-fuse
5、配置cinder使用多后端
cinder type-create glusterfscinder type-key one set volume_backend_name=glusterfscinder extra-specs-list
