问题描述：

分区成功后，使用fdisk -l 查看分区已经存在，但是使用mkfs.ext3 /dev/sda4格式化分区时出现错误：

Could not stat /dev/sda4 --- No such file or directory！！！

解决办法是：

使用partprobe重新读取分区表

使用partprobe必须确保已经安装该命令：

使用rpm -qa |grep parted查看

如上便是已经安装。

[XXXXX]# partprobe

Warning: Unable to open /dev/hdc read-write (Read-only file system). /dev/hdc has been opened read-only.

读取成功！

再次格式化分区，则会成功！

如果输入partprobe出现错误：

Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot.
Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.
Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.
Error: Invalid partition table - recursive partition on /dev/sr0.
