openSuse 42.3 (KDE) 以 root 身分登入
LUKS 加密的 /home 分割區（/sda4 是主分割區，沒有 LVM）儘管已解鎖，但在啟動時無法存取。顯然存在壞塊。
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
然後
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

下次嘗試
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，任何關於如何從這裡繼續進行的建議，我的意思是讓 fsck.ext4 運行或如何潛在的資料遺失不是問題，存在完整備份。 （是的，這是 ext4，即使 fdisk 傳回了 Microsoft 基本資料）
除了瀏覽器和控制台之外沒有其他東西在運行，df -h 也沒有顯示任何內容。如何讓 fsck 開始運作。
