使用fdisk给新增加硬盘分区
1.使用fdisk创建6个分区[1P+1E(5L)] //dev/sdb1 /dev/sdb5 /dev/sdb6 /dev/sdb7 /dev/sdb8 /deb/sdb9
[root@server ~]# fdisk -l Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000aec72 Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 91 524288 82 Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3 91 1045 7658496 83 Linux Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
2.fdisk -cu /dev/sdb开始分区
[root@server ~]# fdisk -cu /dev/sdb //-c:表示丢弃DOS兼容模式，切换到mode模式； -u:表示从柱面分区改为扇区分区
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x94c5ab35.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) Command (m for help):
3.输入m查看帮助
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition //删除创建的分区
l list known partition types //列出分区类型
m print this menu //查看帮助
n add a new partition //创建新分区
o create a new empty DOS partition table
p print the partition table //打印分区表
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit //写入分区表保存
x extra functionality (experts only) Command (m for help):
4.分出一个10M的主分区
Command (m for help): n
Command action
e extended //代表扩展分区
p primary partition (1-4) //代表主分区
p //选择p 主分区
Partition number (1-4): 1
First sector (2048-2097151, default 2048): //默认2048开始
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-2097151, default 2097151): +10M Command (m for help): p Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders, total 2097152 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x94c5ab35 Device Boot Start End Blocks Id System
/dev/sdb1 2048 22527 10240 83 Linux
