Replicated Datasets are now ReadOnly

[Johnny Fartpants]

I might be a little late to the party but I've had a search around the forums and although I've found one or two posts suggesting that replicated datasets should be set to readonly I didn't actually realise that this had been implemented. Last time I checked which was a little while ago this was not the case.

Therefore I just wanted to check that if you should ever want your replicated datasets to not be readonly I assume the only/best way to do this would be from the command line using:

zfs set readonly=off tank/dataset

Appreciate any thoughts.

Which build version (from System -> Information)?

This change got my attention too and I thought this was intentional.

I'm pretty sure that there were one or two more threads in the forum about readonly mounting replicated datasets last month.

I'm pretty sure that was a temporary bug which will be fixed by the next SU: https://bugs.freenas.org/issues/13450.

Thanks for the heads up. As far as I can see the proposed change affects disabled replication jobs only (but I'm fine with read-only replications for enabled replications jobs).

Yeah I'm not sure if that bug report is the same thing you know.

Replicating Datasets and marking them 'Read Only' within ZFS itself on the replica system does appear to be normal behavior on other ZFS appliances like Oracle's so I just assumed FreeNAS implemented it?
