Re: crash in btrfsck, btrfs-debug-tree, etc

I overwrote some part of the first 195641856 bytes of a 1TB (nominal)
btrfs volume (I CTRL-C'd out
before dd finished.) OK, OK, you may stop laughing now. Surely something
similar has happened to
you. No? Then it will, someday.

Now, onto my problems. My first thought was to btrfsck the unmount
volume, but btrfsck crashes:

    # btrfsck /dev/sdc1
    btrfsck: disk-io.c:723: open_ctree_fd: Assertion
`!(!chunk_root->node)' failed.
    Aborted (core dumped)

I have the same fsck error and mount just says "wrong fs type...".

But as far as I know, I never corrupted the drive...

This is Ubuntu Natty.

Just thought I would share that.
