for over a year now with (knock on wood) no issues. I did this because of
the simplicity of setting up RAID under BTRFS and for me at least that is
the biggest attraction. Maybe I'm mistaken, but there almost seemed (and
still is, IMO) an active discouragement for people to use this
configuration. You're not going to attract people to use and test
something if you simultaneously tell them it is toxic. Also, you can't
jump from don't use it, it isn't safe to ok, let's make it the system
In case you are unaware this is a terrible idea for any data you care about
at this point as scrubs don't work for raid5/6 right now and replacing a
lost drive as a result is ... Finicky at best.
Essentially for all intents raid 5/6 is as safe as raid0 and super
experimental without the benefit of a working scrub on raid0 at present ...
Any data you care about on btrfs must be raid1 or raid10 depending on the
number of drives (with metadata and system set to raid1).
