在Linux中划分partition 并格式化为文件系统

本文介绍了如何解决使用mkfs.ext3格式化磁盘分区时遇到的问题，包括无法找到指定设备的情况。通过执行partprobe命令刷新内核分区表，成功完成ext3文件系统的创建。

[root@hvrhub ~]# mkfs.ext3 /dev/sda3
mke2fs 1.39 (29-May-2006)
Could not stat /dev/sda3 --- No such file or directory

The device apparently does not exist; did you specify it correctly?

需要先执行以下partprobe重新读入Linux kernel

[root@hvrhub ~]# partprobe
Warning: Unable to open /dev/sr0 read-write (Read-only file system).  /dev/sr0 has been opened read-only.
[root@hvrhub ~]# mkfs.ext3 /dev/sda3

This filesystem will be automatically checked every 27 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
