linux命令之partprobe
使用fdisk工具只是将分区信息写入到磁盘,如果需要使用mkfs格式化并使用分区,则需要重新启动系统。partprobe 是一个可以修改kernel中分区表的工具,可以使kernel重新读取分区表而不用重启系统。
# partprobe
这个命令执行完毕之后不会输出任何返回信息,你可以使用mke2fs命令在新的分区上创建文件系统。
在Linux中使用fdisk命令进行分区时,有时会遇到“WARNING: Re-reading the partition table failed with error 16: Device or resource busy.The kernel still uses the old table.The new table will be used at the next reboot.”这种告警信息。
