I followed the instructions to do the RAID 1 pool, got it working, and incorrectly assumed that it would be persistent. Though nothing else with unRAID betas are persistent, so don't know why I assumed.
So not knowing anything about BTRFS, I have two questions:
[*]How to restart the RAID 1 balance, without losing any data already existing on the drive.
[*]How to keep this persistent.
Thanks, freenet is working. It is a project that can be quite slow in development. Once loaded the first time, its /opt/freenet/update.sh script finishes the job!
Good luck with the puppy, and protect any wooden furniture legs!
