格式化新分区的时候,报错,提示下面的错误,没有这个文件或目录。
Could not stat /dev/sda7 --- No such fileor directory
The device apparently does not exist; didyou specify it correctly?
[root@linuxidc ~]# mke2fs -t ext4 /dev/sda7
mke2fs 1.41.12 (17-May-2010)
Could not stat /dev/sda7 --- No such fileor directory

解决方法:执行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。
查看是否安装过该命令:
[root@linuxidc~]# rpm -q parted
packageparted is not installed
提示没有安装过,则需要安装parted
安装命令:#yum install parted #前提是保证你的虚拟机可以上网,要从网络下载安装包
[root@linuxidc~]# yum install parted
