<p><span style="color:rgb(85,85,85)"> 通常我们用的比较多的一般都是fdisk工具来进行分区，但是现在由于</span><a href="http://www.chinabyte.com/keyword/%E7%A3%81%E7%9B%98/" rel="noopener noreferrer" target="_blank"><span style="color:rgb(51,51,51)">磁盘</span></a><span style="color:rgb(85,85,85)">越来越廉价，而且磁盘空间越来越大;而fdisk工具他对分区是有大小限制的，它只能划分小于2T的磁盘。但是现在的磁盘空间很多都已经是远远大于2T了，甚至达到2.5T和3T,那要怎么办能，有两个方法，其一是通过卷管理来实现，其二就是通过我们今天谈到的Parted工具来实现对GPT磁盘进行分区操作。</span></p>
<p><span style="color:rgb(85,85,85)"> GPT格式的磁盘相当于原来MBR磁盘中原来保留4个partition table的4*16个字节，只留第一个16个字节，类似于扩展分区，真正的partitiontable在512字节之后，GPT磁盘没有四个主分区的限制。</span></p>
