3.3 LVM卷扩容

[root@localhost ~]# ssm resize -s +10G /dev/vg00/lv00
fsck，来自 util-linux 2.23.2
/dev/mapper/vg00-lv00: 11/65536 files (0.0% non-contiguous), 4763/262144 blocks
 Extending logical volume lv00 to 11.00 GiB
 Logical volume lv00 successfully resized

3.4 创建新的VG

[root@localhost ~]# mkdir /soft
[root@localhost ~]# ssm create -s 1G -n soft --fstype xfs -p mysoft /dev/sde /soft 
//create创建、-s 1G指定大小、-n soft文件名称、--fstype xfs文件系统、-p mysoft指定VG名称、/dev/sde /soft指定那块磁盘挂载哪个目录上
 Physical volume "/dev/sde" successfully created
 Volume group "mysoft" successfully created
 Logical volume "soft" created
