cannot set property for 'backupcloud': permission denied

[jamiec1]

Hi all,

Previously my replication task had been working well using ssh as root but learning more about Linux, I decided to setup a new user called ts on the destination server

Source: TrueNas Core TrueNAS-12.0-U8.1
Dest: Ubuntu 20.04.4 LTS with ZFS 0.8.3-lubuntu12.13 (modinfo zfs | grep version)

I am now getting the following errors:

cannot set property for 'backupcloud': permission denied.

zettarepl.transport.interface.ExecException: cannot set property for 'backupcloud': permission denied

Researching online I found zfs allow backupcloud
Adding the following got rid of a few errors but I can't shift the aclmode issue, so I added userprop, but still no dice!

user ts create,mount,mountpoint,receive,send,sharenfs,sharesmb,snapshot,userprop

Now it is just this:

cannot set property for 'backupcloud': permission denied.

Looking on this forum previous posts suggests:
zfs set aclmode=discard backupcloud

Adding that via the shell in TrueNas made no difference

Is this because of the 'Destination Dataset Read Only Policy' being SET in TrueNas and somehow not being able to be 'set' ?

How to fix, please help !
