"3. Use the GUI to create a snapshot of the dataset you want to move. If you want to move everything, select the root dataset. For flexibility in the future, I'd suggest checking the "recursive" option. Also, minimize use of tank. You will want to pick a time where nothing is changing, then ensure you have a snapshot, and then wait for replication to finish. The amount of time this will take depends on how much storage and the speed of your machine. It took ~36 hours to move 20TB locally for me. [ alternatively, you can use the CLI to create the snapshot and then replicate manually. "zfs snapshot -r tank@migrate" and then "zfs send -R tank@migrate | zfs receive temp-tank"]
I've created a snapshot, but I can't seem to figure out how to start the replication using the GUI. I understand a snapshot does not use any data, but how do you then tell the system to duplicate the data on the other volume? If I add a replication task it wants to know the remote host name, and I am currently only using one FreeNAS system.
