openSuse 42.3（KDE）以 root 身份登录
LUKS 加密的 /home 分区（/sda4 是主分区，没有 LVM）虽然已解锁，但在启动时无法访问。显然存在坏块。
fsck.ext4 -nf /dev/sda4
e2fsck 1.42.11 (09-Jul-2014)
Warning! /dev/sda4 is in use.
ext2fs_open2: Bad magic number in super-block
fsck.ext4: Superblock invalid, trying backup blocks...
fsck.ext4: Bad magic number in super-block while trying to open /dev/sda4
然后
unmount /dev/sda4
umount: /dev/sda4: not mounted
唉
sudo mke2fs -n /dev/sda4
mke2fs 1.42.11 (09-Jul-2014)
/dev/sda4 contains a crypto_LUKS file system
Proceed anyway? (y,n) y
/dev/sda4 is apparently in use by the system; will not make a filesystem here!
下一步
fdisk -l

下次尝试
umount /dev/mapper/A-HDID-part4:
umount: /dev/mapper/A-HDID-part4: not mounted
fsck 再次抱怨它正在使用中。因此，任何关于如何从这里继续的建议，我的意思是让 fsck.ext4 运行或如何潜在数据丢失不是问题，存在完整备份。（是的，这是 ext4，即使 fdisk 返回了 Microsoft 基本数据）
除了浏览器和控制台之外，没有其他程序在运行，df -h 也没有显示任何内容。如何让 fsck 开始运行。
