为什么用fdisk创建的分区无法格式化？

提问：为什么用fdisk创建的分区无法格式化？

[root@as3u9 root]# fdisk /dev/hda
The number of cylinders for this disk is set to 9729.
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
First cylinder (5068-9729, default 506: 5069
Last cylinder or +size or +sizeM or +sizeK (5069-9729, default 9729): +1024M
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: 设备或资源忙.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.

接下来格式化，出错：
[root@as3u9 root]# mke2fs ext3 /dev/hda9
mke2fs 1.32 (09-Nov-2002)
mke2fs: bad blocks count - /dev/hda9

解决办法：

1、你需要重启，才能让内核重新读取新的分区表

2、mke2fs 命令语法错误 。改为 mke2fs -j /dev/hda9
