1.安装ssm
[root@localhost ~]# yum -y install system-storage-manager.noarch
2.检查硬盘和LVM信息
[root@localhost ~]# sudo ssm list ---------------------------------------------------------//物理设备 Device Free Used Total Pool Mount point --------------------------------------------------------- /dev/sda 50.00 GB PARTITIONED /dev/sda1 500.00 MB /boot /dev/sda2 2.02 GB SWAP /dev/sda3 47.50 GB / /dev/sdb 4.00 GB 1.00 GB 5.00 GB vg00 /dev/sdc 5.00 GB 0.00 KB 5.00 GB vg00 /dev/sdd 5.00 GB /dev/sde 5.00 GB --------------------------------------------------------- ----------------------------------------------//存储池 Pool Type Devices Free Used Total ---------------------------------------------- vg00 lvm 2 8.99 GB 1.00 GB 9.99 GB ---------------------------------------------- ----------------------------------------------------------------------------------//存储池中的LVM卷 Volume Pool Volume size FS FS size Free Type Mount point ---------------------------------------------------------------------------------- /dev/vg00/lv00 vg00 1.00 GB ext2 1.00 GB 957.62 MB linear /dev/sda1 500.00 MB xfs 496.67 MB 406.23 MB part /boot /dev/sda3 47.50 GB xfs 47.47 GB 43.87 GB part / ----------------------------------------------------------------------------------
3.将物理磁盘添加到LVM池中
[root@localhost ~]# ssm add -p vg00 /dev/sdd Physical volume "/dev/sdd" successfully created Volume group "vg00" successfully extended
4.查看当前存储池
[root@localhost ~]# ssm list --------------------------------------------------------- Device Free Used Total Pool Mount point --------------------------------------------------------- /dev/sda 50.00 GB PARTITIONED /dev/sda1 500.00 MB /boot /dev/sda2 2.02 GB SWAP /dev/sda3 47.50 GB / /dev/sdb 4.00 GB 1.00 GB 5.00 GB vg00 /dev/sdc 5.00 GB 0.00 KB 5.00 GB vg00 /dev/sdd 5.00 GB 0.00 KB 5.00 GB vg00 /dev/sde 5.00 GB --------------------------------------------------------- ------------------------------------------------ Pool Type Devices Free Used Total ------------------------------------------------ vg00 lvm 3 13.99 GB 1.00 GB 14.99 GB ------------------------------------------------ ---------------------------------------------------------------------------------- Volume Pool Volume size FS FS size Free Type Mount point ---------------------------------------------------------------------------------- /dev/vg00/lv00 vg00 1.00 GB ext2 1.00 GB 957.62 MB linear /dev/sda1 500.00 MB xfs 496.67 MB 406.23 MB part /boot /dev/sda3 47.50 GB xfs 47.47 GB 43.87 GB part / ----------------------------------------------------------------------------------
5.扩大LVM卷
[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 resize2fs 1.42.9 (28-Dec-2013) Resizing the filesystem on /dev/mapper/vg00-lv00 to 2883584 (4k) blocks. The filesystem on /dev/mapper/vg00-lv00 is now 2883584 blocks long.

7.更新文件系统
[root@localhost ~]# mke2fs /dev/vg00/lv00
8.挂载结果
[root@localhost ~]# df -hT 文件系统 类型 容量 已用 可用 已用% 挂载点 /dev/sda3 xfs 48G 3.6G 44G 8% / devtmpfs devtmpfs 906M 0 906M 0% /dev tmpfs tmpfs 914M 80K 914M 1% /dev/shm tmpfs tmpfs 914M 8.9M 905M 1% /run tmpfs tmpfs 914M 0 914M 0% /sys/fs/cgroup /dev/sda1 xfs 497M 116M 382M 24% /boot /dev/mapper/vg00-lv00 ext2 11G 5.0M 11G 1% /mnt
9.创建新的LVM池
[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指定存储池名称、/dev/sde /soft指定那块磁盘挂载哪个目录上
Physical volume "/dev/sde" successfully created

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
