Linux扩容时新建分区报错No free sectors available
扩展后执行fdisk -l查看是否成功# fdisk- l

继续执行fdisk /dev/sda进行新建磁盘
# fdisk/ dev / sda
The number of cylindersfor thisdiskis setto1958 .
Thereisnothing wrong with that, butthis islarger than1024 ,
and couldincertain setups cause problems with:
1 ) software that runs at boot time (e.g., old versions of LILO)
2 ) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS / 2FDISK)
Command (mforhelp): n
No free sectors available
前面执行fdisk -l的时候明明最后才是1305柱面，而且应该有1958柱面，为什么说没有空闲的扇区。
再看看fdisk -l执行结果，原来是/dev/sda5分配了作为swap分区，找到原因了就容易解决。
1.关闭swap分区 # swapoff /dev/sda5
2.删除sda4和sda5.

3.建立扩展分区4，建立分区sda5，写入
