假设我运行了这个虚拟机:

[root@centos ~]# fdisk -ul

Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63      417689      208813+  83  Linux
/dev/sda2         2522205    13799834     5638815   83  Linux
/dev/sda3        13799835    16771859     1486012+  8e  Linux LVM
/dev/sda4          417690     2522204     1052257+   5  Extended
/dev/sda5          417753     2522204     1052226   82  Linux swap /     Solaris

我怎么知道磁盘上有更多分区剩余多少可用空间?

解决方法:

以root用户身份输入shell:


# cfdisk /dev/sdX  #Where /dev/sdX is the device 

它会告诉你这样的事情:

cfdisk (util-linux-ng 2.18)

                          Disk Drive: /dev/sdb
                    Size: 3926949888 bytes, 3926 MB
          Heads: 255   Sectors per Track: 63   Cylinders: 477

Name        Flags      Part Type  FS Type          [Label]        Size (MB)
sdb1                    Primary   vfat             [ABDEL]          1998.75
sdb2        Boot        Primary   ext3             [linx]           1924.72

如果设备有可用空间,则会显示.

注意:cfdisk实际上是一个基于终端的分区编辑器.
