lvm을 사용하여
/dev/sdg1과 /dev/sdh1을 묶어서
/dev/vg01/lvol1으로 사용하다
vgextend로 vg01에 /dev/sdb1을 추가한 후
lvextend로 로지컬 볼륨 사이즈를 늘인후 리마운트를 하니까
마운트가 안돼서 검사한 결과 e2fsck가 고칠수 없는 상태
(superblock을 찾을 수 없는 상태)가 되어버렸습니다. T.T
중요한 자료인데... 어떻게든 복구할 수 없겠습니까?
 [root@natural ~] e2fsck /dev/vg01/lvol1
e2fsck 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09
Couldn't find ext2 superblock, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to
open /dev/vg01/lvol1
 The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
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>
