为zLinux快速扩展磁盘空间的步骤

8.2 创建卷组VG199

[root@zLINUX~]# vgcreate VG199  /dev/dasdc1

Volume group "VG199" successfully created

8.3 查看卷组VG199中空闲PE(Physical extents)个数

[root@zLINUX~]# vgdisplay | grep "Free"

Free  PE / Size      586 / 2.29 GiB

8.4 利用VG199中的全部PE来创建逻辑卷LV199

[root@zLINUX~]# lvcreate -l +586 -n /dev/VG199/LV199

Logical volume "LV199" created

[root@zLINUX~]#vgdisplay  | grep "Free"

Free  PE / Size      0 / 0

8.5 为逻辑卷LV199创建文件系统

[root@zLINUX~]# mke2fs -j /dev/VG199/LV199

mke2fs 1.41.12 (17-May-2010)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

Stride=1 blocks, Stripe width=0 blocks

150176 inodes, 600064 blocks

30003 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=616562688

19 block groups

32768 blocks per group, 32768 fragments per group

7904 inodes per group

Superblock backups stored on blocks:

32768, 98304, 163840, 229376, 294912

Writing inode tables: done

Creating journal (16384 blocks): done

Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 23 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

8.6 修改/etc/fstab表，以使每次系统重启后/image都能被mount上

[root@zLINUX~]# cp /etc/fstab /etc/fstab.bkup
