EXT文件系统坏超级块恢复
# mount /dev/sdb3 /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdb3, missing codepage or helper program, or other error.# fsck /dev/sdb3
fsck from util-linux 2.31.1
e2fsck 1.44.0 (7-Mar-2018)
The filesystem size (according to the superblock) is 483230486 blocks
The physical size of the device is 483230485 blocks
Either the superblock or the partition table is likely to be corrupt!
