​1、卸载挂载中的数据盘：

umount /dev/sdb1

2、使用parted工具读取磁盘分区表信息；先使用 ​​p​​ 查看可扩容磁盘大小，再通过​​unit s​​命令定义默认使用sectors展示，获取起始位置信息：

磁盘扩容_磁盘

3、创建新分区。先使用 ​​rm + 序列号​​ 来删除老的分区表；然后使用 ​​mkpart​​ 命令来创建即可，这里需要注意的是parted工具里END的值，由于一般大家都不清楚具体的扇区数量，可以使用容量来替代。

  • 请注意以下操作步骤需要处于​​​unit s​​​的​​​sectors​​​扇区模式中操作，否则将导致数据盘扩展异常
rm 1
mkpart primary ext4 2048 32.2G

CentOS6(ext4):# resize2fs /dev/vg01/lv00
