I guess it is time for questions now :)
What methods can I use (beside 20-hour-long ZDB walks) to
gain a quick insight on the cause of problems - why doesn't

Besides, the format
is not public and subject to change, I think. So future compatibility
is not guaranteed.
That is not correct.
Years ago, there was a comment in the man

This discussion turns interesting ;)

Just want to share with you. We have found and been suffering from some weird
issues because of
it. It is better to connect them directly to the sata ports on the mainboard.
Thanks.

I wonder if it would be worth adding a (toggleable?) forward error
correction (FEC) [1] scheme to the 'zfs send' stream.

Hi Jim,
I wonder what OS version you are running?
There was a problem similar to what you are describing in earlier versions
in the 13x kernel series.
Should not be present in the 14x kernels.
It is OpenIndiana oi_148a, and unlike many other details -
If it is true that unlike ZFS itself, the replication
stream format has
no redundancy (even of ECC/CRC sort), how can it be
used for
long-term retention on tape?
It can't. I don't think it has been documented anywhere, but I believe that it
has been well understood that if you don't trust

How would it cope with BER in transfers to/from such media?

The tragic irony here is that the file was stored on a non-zfs filesystem. You
had had undetected bitrot which unknowingly corrupted the stream. Other files
also might have been silently corrupted as well.
You may have just made one of the strongest
