RHEL7使用ssm命令管理LVM的方法

linux LVM ssm RHEL 2024-04-03

1.安装ssm

[root@localhost ~]# yum -y install system-storage-manager.noarch

2.检查硬盘和LVM信息

12345678910111213141516171819202122232425 [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

123	`[root@localhost ~]# ssm add -p vg00 /dev/sddPhysical volume "/dev/sdd" successfully createdVolume group "vg00" successfully extended`

4.查看当前存储池

12345678910111213141516171819202122232425 [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

12345678 [root@localhost ~]# ssm resize -s +10G /dev/vg00/lv00fsck，来自 util-linux 2.23.2/dev/mapper/vg00-lv00: 11/65536 files (0.0% non-contiguous), 4763/262144 blocksExtending logical volume lv00 to 11.00 GiBLogical volume lv00 successfully resizedresize2fs 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

12345678910111213141516171819202122232425 [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

123456789 [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% /devtmpfs tmpfs 914M 80K 914M 1% /dev/shmtmpfs tmpfs 914M 8.9M 905M 1% /runtmpfs 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

123456789101112131415 [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 createdVolume group "mysoft" successfully createdLogical volume "soft" createdmeta-data=/dev/mysoft/soft isize=256 agcount=4, agsize=65536 blks= sectsz=512 attr=2, projid32bit=1= crc=0data = bsize=4096 blocks=262144, imaxpct=25= sunit=0 swidth=0 blksnaming =version 2 bsize=4096 ascii-ci=0 ftype=0log =internal log bsize=4096 blocks=2560, version=2= sectsz=512 sunit=0 blks, lazy-count=1realtime =none extsz=4096 blocks=0, rtextents=0

10.查看结果
