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.
6.查看结果
[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
10.查看结果
[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 4.00 gb 1.00 gb 5.00 gb mysoft ----------------------------------------------------------- -------------------------------------------------- pool type devices free used total -------------------------------------------------- mysoft lvm 1 4.00 gb 1.00 gb 5.00 gb 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 /mnt /dev/mysoft/soft mysoft 1.00 gb xfs 1014.00 mb 1013.88 mb linear /soft /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 / ----------------------------------------------------------------------------------------
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? [y/n]: y logical volume "snap20160531t120543" successfully removed do you really want to remove active logical volume soft? [y/n]: y logical volume "soft" successfully removed
