Re: needs help, root inode gone after usb bus reset on sata disks



Oh, so I forgot to mention the main thing which caused e2fsck to
report that various inode tables needed to be moved.  The filesystem
feature field was zero'ed out, and looking at the dumpe2fs output,
it's clear the sparse_super feature should have been enabled.

The backup superblocks should have that feature set; if so, running
e2fsck telling it to pay attention to one of the backup superblocks
should address the problem.

Again, the really funny thing was how the superblock got corrupted in
such a funny and specific way.  It's almost as if it was corrupted by
Murphy (as in Murphy's Law) himself.
