Can you please send a complete list of the actions taken: The
commands you used to create the send stream, the commands used to
receive the stream. Also the output of `zfs list -t all` on both the
sending and receiving sides. If you were able to collect a core dump
(it should be in /var/crash/<hostname>), it would be good to upload it.
The panic you're seeing is in the code that is specific to receiving a
dedup'ed stream. It's possible that you could do the migration if you
turned off dedup (i.e. didn't specify -D) when creating the send
stream.. However, then we wouldn't be able to diagnose and fix what
appears to be a bug.
The best way to get us the crash dump is to upload it here:
https://supportfiles.sun.com/upload
We need either both vmcore.X and unix.X OR you can just send us vmdump.X.
Sometimes big uploads have mixed results, so if there is a problem
some helpful hints are
on
http://wikis.sun.com/display/supportfiles/Sun+Support+Files+-+Help+and+Users+Guide,
specifically in section 7.
It's best to include your name or your initials or something in the
name of the file you upload. As
you might imagine we get a lot of files uploaded named vmcore.1
You might also create a defect report at
http://defect.opensolaris.org/bz/

I kept on trying to migrate my pool with children (see previous
threads) and had the (bad) idea to try the -d option on the receive
part.
The system reboots immediately.
Here is the log in /var/adm/messages

Hello,
I'll try to do my best.
Here are the commands :
amber ~ # zfs unmount data
amber ~ # zfs snapshot -r d...@prededup
amber ~ # zpool destroy ezdata
amber ~ # zpool create ezdata c6t1d0
amber ~ # zfs set dedup=on ezdata
amber ~ # zfs set compress=on ezdata
amber ~ # zfs send -RD d...@prededup |zfs receive ezdata/data
cannot receive new filesystem stream: destination 'ezdata/data' exists
must specify -F to overwrite it
amber ~ # zpool destroy ezdata
amber ~ # zpool create ezdata c6t1d0
amber ~ # zfs set compression=on ezdata
amber ~ # zfs set dedup=on ezdata
amber ~ # zfs send -RD d...@prededup |zfs receive -F ezdata/data
cannot receive new filesystem stream: destination has snapshots (eg.
ezdata/d...@prededup)
must destroy them to overwrite it
Each time the send/receive command took some hours and transferred 151G
data before issuing the message
amber ~ # zfs list
