#fdisk /dev/sde
#fdisk /dev/sdf
#mdadm --create --auto=yes /dev/md10 --level=10 --raid-devices=3 --spare-devices=1 /dev/sd{b,c,d,e}1
#mdadm --detail /dev/md10
建立物理卷
#pvcreate /dev/md10
建立卷组
#vgcreate -s 1m rivervg /dev/md10
建立逻辑卷
#lvcreate -l 10000 -n riverlv rivervg
格式化逻辑卷
#mkfs.ext3 /dev/rivervg/riverlv
建立文件夹LVM
#mkdir /mnt/lvm
挂载
#mount /dev/rivervg/riverlv /mnt/river/
