运行了这个，导致sda1直接废了。。。
里面有一些100G的小文件挪了48小时，不想再挪了
[ol]fsck -v /dev/sda1
fsck from util-linux 2.36.1
e2fsck 1.46.5 (30-Dec-2021)
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/sda1
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
or
e2fsck -b 32768
