[root@doveorc01 iscsi]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xe00b9b36.
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)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

Command (m for help): m

   b   edit bsd disklabel
   c   toggle the dos compatibility flag
   d   delete a partition

   n   add a new partition
   o   create a new empty DOS partition table

   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

[root@doveorc01 iscsi]# fdisk l

先提示一下；用 mkfs.bfs mkfs.ext2 mkfs.jfs mkfs.msdos mkfs.vfatmkfs.cramfs mkfs.ext3 mkfs.minix mkfs.reiserfs mkfs.xfs 等命令来格式化分区，比如我想格式化 sdb1为ext3文件系统，则输入；

[root@doveorc01 /]# mkfs.ext3 /dev/sdb1

Writing inode tables: done
Creating journal (4096 blocks): done

This filesystem will be automatically checked every 27 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

[root@doveorc01 /]# mkdir /mnt/sdb1
[root@doveorc01 /]# mount /dev/sdb1 /mnt/sdb1

自动平挂接

[root@doveorc01 /]#vi /etc/fstab
最后一行追加如下：
/dev/sdb1 /mnt/sdb1 ext3 default 0 0
