parted扩大ext4分区

笔记本硬盘160G装的archlinux，近一年没有更新，一更新就应为glibc2.16的问题挂了。懒得搞，就把台式机的64GSSD硬盘dd到笔记本硬盘上了。不过这样一来，160G就变成了64G的GPT分区。下一步应该把分区扩大到160G，不过fdisk不支持gpt，gdisk里没有resize，parted里面也没有，应该是现在还不支持对ext4分区的直接resize。搜到了http://ubuntuforums.org/showthread.php?t=1389429，步骤如下：

• Run parted on your device: parted /dev/sdX
• Change display unit to sectors: unit s
• Print current partition table and note the start sector for your partition: p
• Delete your partition (won't delete the data or filesystem): rm <number>
• Recreate the partition with the starting sector from above: mkpart primary <start> <end>
• Exit parted: quit
• Check the filesystem: sudo e2fsck -f /dev/sdXX
• Resize filesystem: sudo resize2fs /dev/sdXX

照此方法resize成功。
