Perhaps an option here is to remove the need to specify the degraded flag but
if the filesystem notice that it is mounting a RAID array and would otherwise
fail it then sets the degraded flag itself and carries on?
That way the fact it was degraded would be visible in /proc/mounts and could
be detected with health check scripts like NRPE for icinga/nagios.
Looking at the code this would be in read_one_dev() in fs/btrfs/volumes.c ?
All the best,
Chris
