11.3 Trouble setting up replication from Debian box

[Sarsi]

Hi, my main NAS runs Debian Buster, I recently came into possession of a N40L microserver and decided to use this as a backup destination using zfs replication. I chose FreeNAS mainly to run it from a usb stick.

I've followed the documentation to setup the SSH Keypair and SSH Connection, copying the public key over to my debian box. When I go to setup the replication task with the debian box as the source location and click on the folder to choose the source I get an error

ExecException
sh: 1: zfs: not found

Code:

Error: Traceback (most recent call last):

I suspect this may be to do with the ssh connection, if I go to the shell and ssh to the debian box using my user name I am still asked for a password. I believe I have the public key setup correctly as I've set this up correctly to ssh to the debian box from my workstation but I could have some detail wrong.

Is the freenas shell a valid way to test if the ssh connection is setup correctly or does the error message above indicate the issue is elsewhere?

I have seen reference to this in the case of replication between TrueNAS 12 and FreeNAS 11.3 where the location of some binaries are different.

You may be able to find that post and the equivalent location of the right binaries and ln -s to them in their actual location, but basically the intention of the replication via GUI is to be between 2 TrueNAS/FreeNAS servers, not to another type of storage box. Maybe you're looking for the upcoming TrueNAS SCALE (linux based).
