磁盘是怎么分区的在文章后面会谈到，先谈一下Linux文件系统的简单操作。不过在阅读本文之前，我假定读者们对Linux的磁盘与文件系统以及目录树已经有了初步的了解。...sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes...，z表示的是硬盘序号，第一块硬盘是a，第二块硬盘是b，所以要查询Linux系统上有几块硬盘，只要注意这一点即可。...sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes...Disk /dev/mapper/cl-root: 8585 MB, 8585740288 bytes, 16769024 sectors Units = sectors of 1 * 512 =
