"This patchset will introduce a new per-chunk degradable check for btrfs, allow above case to succeed, and it's quite small anyway." My raid1 is "-m raid1 -d raid1". Both the same duplication level. Would that patch make any difference? And: What do I need to do to test this in "debian stable"? I am not a programmer - but I know how to use git and how to compile with proper configuration directions.
