接上篇, 接下来创建存储池, 然后建立 Volume 了.

4. 创建池:

$ gluster peer probe gluster2
$ gluster peer probe gluster3
# 查看池
$ gluster pool list

5. 创建 Volume 前的目录准备工作

$ ansible glusterfs -m file -a "path=/bricks/ovirt/brick state=directory"
$ ansible glusterfs -m file -a "path=/bricks/openshift/brick state=directory"
$ ansible glusterfs -m file -a "path=/bricks/openstack/brick state=directory"
# 这个包为了管理 selinux 方便
$ ansible glusterfs -m yum -a "name=policycoreutils-python"
# 更改 selinux 标签
$ ansible glusterfs -m shell -a "semanage fcontext -a -t glusterd_brick_t /bricks/ovirt/brick"
$ ansible glusterfs -m shell -a "semanage fcontext -a -t glusterd_brick_t /bricks/openshift/brick"
$ ansible glusterfs -m shell -a "semanage fcontext -a -t glusterd_brick_t /bricks/openstack/brick"
$ ansible glusterfs -m shell -a "restorecon -Rv /bricks"

6.  创建 Volume, 这里三种方式都用

# replica 2 with arbiter 1
# rdma 的传输方式在虚拟机上可能不支持, 这里写不写都可以
$ gluster volume create ovirt replica 3 arbiter 1 transport tcp,rdma gluster1:/bricks/ovirt/brick gluster2:/bricks/ovirt/brick gluster3:/bricks/ovirt/brick
# distribute
$ gluster volume create openstack gluster1:/bricks/openstack/brick gluster2:/bricks/openstack/brick gluster3:/bricks/openstack/brick
# disperse
$ gluster volume create openshift disperse 3 disperse-data 2 transport tcp gluster1:/bricks/openshift/brick gluster2:/bricks/openshift/brick gluster3:/bricks/openshift/brick

7. 在 DNS 上验证一下

$ yum -y install glusterfs-fuse
$ cd /mnt && mkdir {ovirt,openstack,openshift}
$ mount -t glusterfs gluster1:/ovirt /mnt/ovirt/
$ mount -t glusterfs gluster1:/openshift /mnt/openshift/
$ mount -t glusterfs gluster1:/openstack /mnt/openstack/
$ df -hT
