安装ssm工具：SSM：检查关于可用硬驱和LVM卷的信息。显示关于现有磁盘存储设备、存储池、LVM卷和存储快照的信息
[root@localhost ~]# rpm -ivh /mnt/Packages/system-storage-manager-0.4-7.el7.noarch.rpm 加一块新的sdb盘fdisk分区sdb全部空间分区给sdb1

--------------------------------存储池信息，由于没有lvm所以没有任何提示
[root@localhost ~]# ssm list poolssm工具可以自动分区挂载。还是推荐lvm一步一步来。
创建目录：用于挂载使用
[root@localhost ~]# mkdir /data用的命令如下：
ssm create -s lv大小 -n lv名称 --fstype lv文件系统类型 -p 卷组名 设备 挂载点
自动把设备变成pv，创建vg、lv、格式化文件系统、自动挂载
自动创建pv、vg、lv、格式化、挂载
[root@localhost ~]# ssm create -s 20G -n data --fstype xfs -p centos /dev/sdb1 /data/

[root@localhost ~]# ssm resize -s +20G /dev/centos/data
SSM Error (2005): There is not enough space in the pool 'centos' to grow volume '/dev/centos/data' to size 41938944.0 KB!报错：因为vg空闲容量步到20G。
解决办法：先执行一次19.9G，在vgs查看生于多少，在执行命令把剩余的加入进来。
