  • 创建逻辑卷的过程

    首先分区:
    # fdisk /dev/sda
    The number of cylinders for this disk is set to 60801.
    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):p
    Disk /dev/sda: 500.1 GB, 500107862016 bytes
    255 heads, 63 sectors/track, 60801 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1       12748   102398278+  83  Linux
    /dev/sda2           12749       13270     4192965   82  Linux swap / Solaris
    Command (m for help): n
    Command action
       e   extended
       p   primary partition (1-4)
    p
    Partition number (1-4): 3
    First cylinder (13271-60801, default 13271): 
    Using default value 13271
    Last cylinder or +size or +sizeM or +sizeK (13271-60801, default 60801): 
    Using default value 60801
    Command (m for help): t
    Partition number (1-4): 3
    Hex code (type L to list codes): 8e
    Changed system type of partition 3 to 8e (Linux LVM)
    Command (m for help): w
    The partition table has been altered!
    Calling ioctl() to re-read partition table.
    执行下面的命令不必重启机器:
    # partprobe 这个命令必须记住,老是忘记
    创建物理卷:
    # pvcreate /dev/sda3
    创建卷组:
    # vgcreate xenvg /dev/sda3 
    创建逻辑卷:
    # lvcreate -L 10G -n test xenvg
