Thanks! :-)
No, wait! ....
According to that page, if you "zfs receive -n" then you should get
a 0 exit
status for success, and 1 for error.
Unfortunately, I've been sitting here and testing just now ... I
created a
"zfs send" datastream, then I made a copy of it and toggled a bit in
the
middle to make it corrupt ...
I found that the "zfs receive -n" always returns 0 exit status, even
if the
data stream is corrupt. In order to get the "1" exit status, you
have to
get rid of the "-n" which unfortunately means writing the completely
restored filesystem to disk.
I believe it will depend on the nature of the corruption. Regardless,
the answer is to use zstreamdump.
