Hi,
I should have put this in the subject; the receiving zpool is on a
FreeNas 9.3 box.
When I did as described by you, i e "zfs send -R pool/name@snap | ..."
the resulting dataset on Freenas didn't really work.
When trying to set up a share for the dataset on Freenas, I got
"unsupported share protocol:1" and sharing failed.
It seems this has to do with zfs properties and the fact that ZFS has
hooks in the kernel in OI but not in FreeNas.
A short look in the FreeBSD's zfs man page gives the impression that it
only supports sharing via NFS (OI/Solaris also support CIFS), and you have
to enable the NFS server part in your /etc/rc.conf; see for example
https://forums.freebsd.org/threads/creating-a-zfs-network-share-over-nfs.34828/
For FreeBSD you're right, but FreeNAS has done that already, and can
handle exporting via CIFS and NFS from the webgui.
I'm guessing that just doing a "zfs send pool/name@snap", i e not using
-rp or -R, will make a working dataset on FreeNas which can then be
shared.
If you're only interested in the data sets, not in their properties, "-r"
will suffice.
-r just gets me an error message "invalid option r". I'm on OI 151a7,
which might be relevant.
send w/o option seems to get the data across, ignoring any options and such.
As a side note; just piping to ssh is excruciatingly slow, using netcat,
"nc", speeds things up at least 4fold.
On the receiving end:
nc -w 600 -l 8023 | zfs recv pool/name
and on the sending end
zfs send pool/data@snap|nc -w 20 receive-address 8023
Well, I don't know, I got this info from the web, and it supposedly
applies to SmartOS and several other environments, and FreeNAS.
And to my setup.
Hm, I can't confirm that. Perhaps this has to do with the hardware you're
using...?

Thorsten
