Hi!
Currently I have 2 "servers": the "master" has an i3 CPU and 16GB of RAM; the "slave" has a XEON-E3 and 64GB of RAM. (I'm calling them "master" and "slave" but actually the "master" is where the jails are running and the "slave" is working just as a backup system, but of course this is about to change...)
I need to switch "roles", so that the current master will be the slave and vice-versa.
Both of them has 2 pools with the same name: "storage" for data and "system" for system dataset.
The "storage" pools are synced between the two servers, but the "system" is not, because of "* Replication system -> freenas.local:system failed: Please move system dataset of remote side to another pool", and I perfectly understand the reason.
So the question is: how can I make this server swap with a minimum downtime?
Ideally I would like to stop the jails in the current master, make a final replication so both will be 100% equalized, and them start the jails on the current "slave".
Thanks.
Regards.
