If there are no common snapshots, then the first question is "how did we

Where to begin...

Thanks for the info.
If that last common snapshot gets destroyed on the primary server, it is then a
full replication back to the primary server. Is that correct?

I have additional problem, whicxh worries me.
I tried different ways of sending/receiving my data pool.
I took some snapshots, sent them, then destroyed them, using destroy -r.
AFAIK this shoud not have affected the filesystem's _current_ state or am I

Now I succeeded to send a snapsho

Sorry if my question was confused.
Yes I'm wondering about the catch22 resulting of the two errors : it means we
are not able to send/receive a pool's root filesystem without using -F.
The zpool list was just meant to say it was a whole pool...

Until zfs-crypto arrives, I am using a pool for sensitive data inside
several files encrypted via lofi crypto. The data is also valuable,
of course, so the pool is mirrored, with one file on each of several
pools (laptop rpool, and a couple of usb devices, not always
connected).
