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

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"?

Using debugfs, copy out the the contents of "root inode"; since it
might contain useful data, e2fsck didn't want to delete it out of

debugfs: dump <2> /tmp/contents-of-inode-2

Then purge the inode away:

debugfs: clri <2>

Then run e2fsck, and it will create a new root directory for you.

Hope this helps!
