zfs send recv be newby question

[Joe Veliscos via illumos-zfs]

Hi all,

If you snapshot a BE on one system with the beadm command, is it possible
to zfs send / recv that snaphot to another identical system into a testBE
(in order to test that same BE on that system) ? If yes can someone tell me
the commands how to do that?

What I've done is:
- create a be on system 1 called system1
- snapshot that be on system 1 called rpool/ROOT/***@monday
- create a testbe on system 2 called fromsystem1

zfs send rpool/ROOT/***@monday | ssh system2 zfs recv -F
rpool/ROOT/fromsystem1

but then I get: cannot receive new filesystem stream: destination
'rpool/ROOT/fromsystem1' is a clone
must destroy it to overwrite it

I have tried several combinations of commands but no luck

Regards,

Joe

IIRC beadm should recognize any fs under rpool/ROOT. So you won't need to
"create a testbe on system 2 called fromsystem1".

Then again, there are other additional configuration involved (e.g. grub),
so you can probably try destroying (or renaming) rpool/ROOT/fromsystem1 to
something else before "zfs recv".
