Linux 格式化分区 报错Could not stat --- No such file or directory 和 partprobe 命令

分区的过程正常：
[root@db1 /]# fdisk
-l
Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

End Blocks Id System

/dev/sda2 14
650 5116702+ 83 Linux
/dev/sda3 651
841 1534207+ 82 Linux swap /
Solaris
[root@db1 /]# fdisk
/dev/sda
The number of cylinders for this disk is set to 2610.
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)

再次查看，分区已经划好：
[root@db1 /]# fdisk
-l
Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda2 14
650 5116702+ 83 Linux
/dev/sda3 651
841 1534207+ 82 Linux swap /
Solaris
/dev/sda4 842
2610 14209492+ 83 Linux
但是格式化的时候，报错：
[root@db1 /]# mkfs -t
ext3 /dev/sda4
mke2fs 1.39 (29-May-2006)
Could not stat /dev/sda4 --- No such
file or directory
The device apparently does not exist; did you specify it correctly?
解决方法：执行下partprobe 命令
partprobe包含在parted的rpm软件包中。partprobe可以修改kernel中分区表，使kernel重新读取分区表。 因此，使用该命令就可以创建分区并且在不重新启动机器的情况下系统能够识别这些分区。
查看是否安装该命令：
[root@db1 dev]# rpm -q
parted
parted-1.8.1-23.el5
我们执行一下该命令：
[root@db1 dev]# partprobe
Warning: Unable to open /dev/hdc read-write (Read-only file system).
/dev/hdc has been opened read-only.
然后在格式化，就ok了：
[root@db1 dev]# mkfs -t ext3
/dev/sda4
mke2fs 1.39 (29-May-2006)
