热区准备：分区，格式化，创建挂载目录，编辑挂载配置文件，进行挂载。
冷区准备：从瘦池划分LV，格式化，创建挂载目录，编辑挂载配置文件，进行挂载。

Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

2.配置分层
配置冷区，启动存储卷，添加分层到热区。
[root@servera ~]# gluster volume create tiervol replica 2 serverc:/bricks/tier/tiervol_n3 serverd:/bricks/tier/tiervol_n4
volume create: tiervol: success: please start the volume to access data
[root@servera ~]# gluster volume start tiervol
volume start: tiervol: success
[root@servera ~]# gluster volume tier tiervol attach servera:/bricks/tier/tiervol_n1 serverb:/bricks/tier/tiervol_n2
volume attach-tier: success
Tiering Migration Functionality: tiervol: success: Attach tier is successful on tiervol. use tier status to check the status.

3.配置快照
使用存储卷创建快照。
[root@servera ~]# gluster snapshot create snap-secvol secvol no-timestamp
snapshot create: success: Snap snap-secvol created successfully
