ext4 文件系统已损坏。所以我对该分区运行了 fsck。但是，fsck完成后，我仍然无法挂载文件系统。现在它报告超级块已损坏。
[root@os1 ~]# mount /dev/sda2 /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error.
[root@os1 ~]# fsck /dev/sda2
fsck from util-linux 2.32.1
e2fsck 1.45.4 (23-Sep-2019)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda2
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
尝试通过查找备份超级块 ( mkfs.ext4 -n /dev/sda2) 并用于e2fsck -b superblocks /dev/sda2恢复来从备份超级块恢复。但是，它总是返回相同的错误消息。
我现在该怎么办？
