The error as originally reported is due to btrfs converting meta and
system data to RAID1 when adding a second device to a single device
filesystem and rebalancing. You can then no longer go below 2 devices.
Check dmesg or /var/log/syslog as suggested. The remedy is to mconvert
to single and remove the device then. Then another mconvert to DUP.
Cumbersome indeed, but not a bug.
Most comments from #8 onwards are about different issues and should be
dealt with in their own tickets.
