요즘 LINUX 서버 셋팅과 관리해주는 허접한 일들을 해주고 있다.
200 GB 하드 2개를 하나로 합쳐야 하는 상황이 와서
SOFT RAID 를 시도해 보았으나..
짧은 지식과 능력으로 인해 실패..
LVM 으로 다시 시도해 보게 되었다.
참고문서 : http://doc.kldp.org/wiki.php/DocbookSgml/LVM-HOWTO
먼저 fdisk 를 이용해 LVM 으로 묶을 파티션을 Linux LVM 시스템으로 바꾸어 준다
같은 방법으로 다른 하드의 파티션 까지...
이제 lvmtab 을 생성해야 한다.
이제 물리적 볼륨을 만들어야 한다

[root@localhost /]# fdisk /dev/hda
The number of cylinders for this disk is set to 24321.
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)
Command (m for help): t
Selected partition 1
Hex code (type L to list codes): 8e
Changed system type of partition 1 to 8e (Linux LVM)
Command (m for help): p
Disk /dev/hda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 24321 195358401 8e Linux LVM
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

이제 lvmtab 을 생성해야 한다.
