Unfortunately, I am going to have to give up on btrfs if it
is really so fragile.

However, complaining about the fragility of a still in development
and 
marked experimental filesystem would seem disingenuous at best.  

[snip paragraphs of tut-tutting]

IOW, yes, btrfs is to be considered fragile at this point.

So you re-stated my position.  I gave btrfs a chance but it is still
apparently far more fragile than ext4 when corruption is introduced --
although btrfs is the filesystem of the two which is specifically
designed to provide internal fault tolerance and resilience.  Is there
a fine line between "user feedback" and "disingenuous complaining"
that I am not aware of?

The data in question is not that important, though I would like to
have it back considering it should mostly still be there as on the
ext4 volumes.  40MB of bad sectors on one 2TB disk in a 6TB volume
does not seem like a lot.  Even if the whole beginning of the volume
was wiped out surely there is the equivalent of backup superblocks?  I
can hack if I could just get a clue where to start.
