Du scheinst ein 4k blocksize zu verwenden. |
31 |

32 |
Versuch doch mal, ob Du einen anderen superblock bei 32768 findest. |
33 |
|
34 |
aus man fsck.ext3: |
35 |
-b superblock |
36 |
|
37 |
Instead of using the normal superblock, use an alternative |
38 |
superblock specified by superblock. This option is normally used |
39 |
when the primary superblock has been corrupted. The location of |
40 |
the backup superblock is dependent on the filesystem's |
41 |
blocksize. For filesystems with 1k blocksizes, a backup |
42 |
superblock can be found at block 8193; for filesystems with 2k |
43 |
blocksizes, at block 16384; and for 4k blocksizes, at block |
44 |
32768. |
45 |
Additional backup superblocks can be determined by using the |
46 |
mke2fs program using the -n option to print out where the |
47 |
superblocks were created. The -b option to mke2fs, which |
48 |
specifies blocksize of the filesystem must be specified in order |
49 |
for the superblock locations that are printed out to be |
50 |
accurate. |
51 |
If an alternative superblock is specified and the filesystem is |
52 |
not opened read-only, e2fsck will make sure that the primary |
53 |
superblock is updated appropriately upon completion of the |
54 |
filesystem check. |
