linux - e2fsck如何修复磁盘
我的debian8开机时，总是出现下面的提示：
[ 908.954911] ata5.00: status: { DRDY ERR }
[ 923.285748] ata5.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0

查了资料说是磁盘需要修复。
e2fsck -a /dev/sda2
/dev/sda2 is mounted.
e2fsck: Cannot continue, aborting.
umount /dev/sda2
umount: /home: target is busy
(In some cases useful info about processes that
use the device is found by lsof(8) or fuser(1).)
请问，如何处理？
