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


    [root@localhost ~]# fdisk /dev/sda
    
    The device presents a logical sector size that is smaller than
    the physical sector size. Aligning to a physical sector (or optimal
    I/O) size boundary is recommended, or performance may be impacted.
    欢迎使用 fdisk (util-linux 2.23.2)。
    
    更改将停留在内存中,直到您决定将更改写入磁盘。
    使用写入命令前请三思。

    分区号 (3,4,默认 3):
    起始 扇区 (3907024896-3907029167,默认为 3907024896):
    将使用默认值 3907024896
    Last 扇区, +扇区 or +size{K,M,G} (3907024896-3907029167,默认为 3907029167):
    将使用默认值 3907029167
    分区 3 已设置为 Linux 类型,大小设为 2.1 MiB
    
    命令(输入 m 获取帮助):w
    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 or after you run partprobe(8) or kpartx(8)

    分区正常,格式化错误。
    [root@localhost ~]# mkfs  /dev/sda3
    mke2fs 1.42.9 (28-Dec-2013)
    无法对 /dev/sda3 进行 stat 调用 --- 没有那个文件或目录
    
    The device apparently does not exist; did you specify it correctly?
    

    原因是分区信息尚未到分区表里,

    解决方法:执行下partprobe 命令

    [root@localhost ~]# partprobe
    [root@localhost ~]# mkfs -t ext4 /dev/sda3
    mke2fs 1.42.9 (28-Dec-2013)
