/dev/mapper/ubuntu--vg-ubuntu--lv does not exist. Dropping to a shell!

fsck.ext2: Bad magic number in super-block while trying to open /dev/sda3
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>

是否有可能“重新创建” ubuntu--vg-ubuntu--lv？
