利用 LVM 增加磁盘空间

背景：

 现有一个分区时lvm分区，但是空间不够大。现还有一个普通分区空间也不够大，所以想把普通分区重新全部划分给lvm分区，文件已经备份好。

操作步骤：

1.       

      1.       卸载分区

[root@LOCALSERVER ~]# umount /backup/

      2.       查看当前分区

[root@LOCALSERVER ~]# fdisk –l

Disk /dev/cciss/c0d0: 1350.1 GB, 1350193700864 bytes

255 heads, 63 sectors/track, 164151 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

[root@LOCALSERVER ~]#

      3.       由此可见，需要重新划分/dev/cciss/c0d0p8分区。

      4.       调整新分区

[root@LOCALSERVER ~]# fdisk /dev/cciss/c0d0

[root@LOCALSERVER ~]# fdisk /dev/cciss/c0d0

The number of cylinders for this disk is set to 164151.

There is nothing wrong with that, but this is larger than 1024,

and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

   (e.g., DOS FDISK, OS/2 FDISK)
