我的AS4为啥fdisk之后，总要重启才能mkfs？

celi

fdisk，w之后，提示如下:

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.

[root@x260 /]#

[root@x260 /]# mkfs -V -t ext3 /dev/sda5
mkfs version 2.12a (Jul 27 2005)
mkfs.ext3 /dev/sda5
mke2fs 1.35 (28-Feb-2004)
Could not stat /dev/sda5 --- 没有那个文件或目录

The device apparently does not exist; did you specify it correctly?
[root@x260 /]#

重启之后才能作，我是linux菜鸟，希望得到帮助，谢谢。
