fixing a corrupt /dev/hdar .. debugfs assistance...

[Chris Worley]

Thanks for the help.

Does <2> refer to a superblock?  I.e.:

Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632,
2654208,
        4096000, 7962624, 11239424, 20480000, 23887872, 71663616

The debugfs man page says the first arg of "clri" refers to a "file"?

Thanks,

Chris
