RHEL7使用ssm命令管理LVM

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.

[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   0.00 KB  5.00 GB    5.00 GB  vg00             /dev/sdc   0.00 KB  5.00 GB    5.00 GB  vg00             /dev/sdd   3.99 GB  1.01 GB    5.00 GB  vg00             /dev/sde                       5.00 GB                   --------------------------------------------------------- ------------------------------------------------ Pool  Type  Devices     Free      Used     Total  ------------------------------------------------ vg00  lvm   3        3.99 GB  11.00 GB  14.99 GB  ------------------------------------------------ ---------------------------------------------------------------------------------- Volume          Pool  Volume size  FS      FS size       Free  Type    Mount point ---------------------------------------------------------------------------------- /dev/vg00/lv00  vg00     11.00 GB  ext2   11.00 GB   10.31 GB  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    /          ----------------------------------------------------------------------------------

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   Volume group "mysoft" successfully created   Logical volume "soft" created meta-data=/dev/mysoft/soft       isize=256    agcount=4, agsize=65536 blks          =                       sectsz=512   attr=2, projid32bit=1          =                       crc=0 data     =                       bsize=4096   blocks=262144, imaxpct=25          =                       sunit=0      swidth=0 blks naming   =version 2              bsize=4096   ascii-ci=0 ftype=0 log      =internal log           bsize=4096   blocks=2560, version=2          =                       sectsz=512   sunit=0 blks, lazy-count=1 realtime =none                   extsz=4096   blocks=0, rtextents=0

11.对LVM卷快照

[root@localhost ~]# ssm snapshot /dev/mysoft/soft   Rounding up size to full physical extent 208.00 MiB   Logical volume "snap20160531T120543" created [root@localhost ~]# ssm list snapshots ------------------------------------------------------------------------------ Snapshot                         Origin  Pool    Volume size      Size  Type  ------------------------------------------------------------------------------ /dev/mysoft/snap20160531T120543  soft    mysoft    208.00 MB  21.30 KB  linear ------------------------------------------------------------------------------

12.删除LVM卷

[root@localhost ~]# ssm remove /dev/mysoft/soft Device '/dev/mysoft/soft' is mounted on '/soft' Unmount (N/y/q) ? Y Do you really want to remove active logical volume snap20160531T120543?
