openstack I版的搭建一十--基于glusterfs的云硬盘
计算节点和控制节点上都安装一下
cd /etc/yum.repos.d/
wget http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.3/CentOS/glusterfs-epel.repo
yum install glusterfs-server
验证一下两个节点是否安装成功
[root@linux-node1 ~]# glusterfs -V

启动
[root@linux-node1 ~]# /etc/init.d/gluster
glusterd glusterfsd
[root@linux-node1 ~]# /etc/init.d/glusterd start
Starting glusterd: [确定]
[root@linux-node2 ~]# /etc/init.d/glusterd start
Starting glusterd: [确定]
[root@linux-node1 ~]# cat /etc/hosts

[root@linux-node2 ~]# cat /etc/hosts

192.168.33.12 linux-node2.openstack.com linux-node2
192.168.33.11 linux-node1.openstack.com linux-node1
[root@linux-node1 ~]# mkdir /data/gg1
[root@linux-node2 ~]# mkdir /data/gg2
咱们创建一个复制的卷，复制两份
[root@linux-node2 ~]# gluster peer detach linux-node1.openstack.com
peer detach: success
[root@linux-node2 ~]# gluster peer status
peer status: No peers present
把另外一个节点加入到集群
把node1加入集群
glusterfs无中心的，对等的。
[root@linux-node2 ~]# gluster peer probe linux-node1.openstack.com
peer probe: success
[root@linux-node2 ~]# gluster peer status
Number of Peers: 1
Hostname: linux-node1.openstack.com
Port: 24007
Uuid: af7dd374-12c0-4201-8415-fe1a1e22f851
State: Peer in Cluster (Connected)
[root@linux-node2 ~]# gluster volume create demo replica 2 linux-node1.openstack.com:/data/gg1 linux-node2.openstack.com:/data/gg2 force
volume create: demo: success: please start the volume to access data
启动卷
[root@linux-node2 ~]# gluster vol start demo
volume start: demo: success
我们查看一下，我们可以看到，你的数据是放两份的
[root@linux-node2 ~]# gluster vol info
Volume Name: demo
Type: Replicate
Volume ID: ced081c2-a4de-4f00-8260-5fc0fb36ea9f
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: linux-node1.openstack.com:/data/gg1
Brick2: linux-node2.openstack.com:/data/gg2
我们要用这个卷，我们该怎么办？该修改配置文件
1830gg
volume_driver=cinder.volume.drivers.glusterfs.GlusterfsDriver
1107
glusterfs_shares_config=/etc/cinder/glusterfs_shares
1120
glusterfs_mount_point_base=$state_path/mnt
我们要先把NFS卸载掉
umount 192.168.33.11:/data/nfs
查看一下
mount
重启一下cinder的相关服务
[root@linux-node1 ~]# for i in {api,scheduler,volume};do /etc/init.d/openstack-cinder-$i restart;done
停止 openstack-cinder-api： [确定]
正在启动 openstack-cinder-api： [确定]
停止 openstack-cinder-scheduler： [确定]
正在启动 openstack-cinder-scheduler： [确定]
停止 openstack-cinder-volume： [确定]
正在启动 openstack-cinder-volume： [确定]
[root@linux-node1 ~]# mount

创建云硬盘
我们查看一下云硬盘都存在哪
[root@linux-node1 ~]# cat /etc/cinder/glusterfs_shares
192.168.33.11:/demo
[root@linux-node1 ~]# mount

[root@linux-node1 ~]# ll /var/lib/cinder/mnt/4ac2acc000ff60653979b4a905bdecb3

一共有三份
挂载到虚拟机实例上
接下来，我们要对这块硬盘进行格式化
sudo fdisk /dev/vdb
sudo mkfs.ext3 /dev/vdb1
本地文件系统是最好的。
