In some cases useful info is found in syslog - try

At first glance, this looks confusing since it is referring to md0,
which would be md's raid.
Is it a btrfs-raid0 using an md-raid-something-else -> Or is it simply
btrfs on top of an md-raid0?
cat /proc/mdstat
and
btrfs fi show
will answer those queries.
