很久都没有操作都忘的差不多了，重新练练，加深点印象。

  这些操作都是在VMWare虚拟机上进行的。首先把RHEL5安装在/dev/sda上。安装完后从添加了四块硬盘，分别是/dev/sdb、/dev/sdc、/dev/sdd、/dev/sde   以root进入系统，首先看一下磁盘的情况：  [root@www.linuxidc.com ~]# fdisk -l   Disk /dev/sda: 15.0 GB, 15032385536 bytes   255 heads, 63 sectors/track, 1827 cylinders   Units = cylinders of 16065 * 512 = 8225280 bytes      Device Boot Start End Blocks Id System   /dev/sda1 * 1 13 104391 83 Linux   /dev/sda2 14 1827 14570955 8e Linux LVM   Disk /dev/sdb: 8589 MB, 8589934592 bytes   255 heads, 63 sectors/track, 1044 cylinders   Units = cylinders of 16065 * 512 = 8225280 bytes      Device Boot Start End Blocks Id System   Disk /dev/sdc: 8589 MB, 8589934592 bytes   255 heads, 63 sectors/track, 1044 cylinders   Units = cylinders of 16065 * 512 = 8225280 bytes      Device Boot Start End Blocks Id System   Disk /dev/sdd: 8589 MB, 8589934592 bytes   255 heads, 63 sectors/track, 1044 cylinders   Units = cylinders of 16065 * 512 = 8225280 bytes      Device Boot Start End Blocks Id System   Disk /dev/sde: 8589 MB, 8589934592 bytes   255 heads, 63 sectors/track, 1044 cylinders   Units = cylinders of 16065 * 512 = 8225280 bytes      Device Boot Start End Blocks Id System   一.创建Soft RAID   1.创建raid分区   [root@www.linuxidc.com ~]# fdisk /dev/sdb   The number of cylinders for this disk is set to 1044.   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): n   Command action      e extended      p  primary partition (1-4)   p   Partition number (1-4): 1   First cylinder (1-1044, default 1):   Using default value 1   Last cylinder or +size or +sizeM or +sizeK (1-1044, default 1044):   Using default value 1044   Command (m for help): t   Selected partition 1   Hex code (type L to list codes): L    0  Empty           1e  Hidden W95 FAT1 80  Old Minix       be  Solaris boot    1  FAT12           24  NEC DOS         81  Minix / old Lin bf  Solaris    2  XENIX root      39  Plan 9          82  Linux swap / So c1  DRDOS/sec (FAT-    3  XENIX usr       3c  PartitionMagic  83  Linux           c4  DRDOS/sec (FAT-    4  FAT16 <32M      40  Venix 80286     84  OS/2 hidden C:  c6  DRDOS/sec (FAT-    5  Extended        41  PPC PReP Boot   85  Linux extended  c7  Syrinx    6  FAT16           42  SFS             86  NTFS volume set da  Non-FS data    7  HPFS/NTFS       4d  QNX4.x          87  NTFS volume set db  CP/M / CTOS / .    8  AIX             4e  QNX4.x 2nd part 88  Linux plaintext de  Dell Utility    9  AIX bootable    4f  QNX4.x 3rd part 8e  Linux LVM       df  BootIt    a  OS/2 Boot Manag 50  OnTrack DM      93  Amoeba          e1  DOS access
