Well, I can't make out what this is supposed to mean, but no output file...
Dunno. Maybe btrfs-show-super -fa for each device, along with
btrfs-debug-tree <dev> output to a file might have some useful info
for a dev. It could be a while before we hear from one though,
considering the season.
The btrfs-debug-tree creates about 56.3 megabytes of text for each
device a few checksums (marked [match]) and dev.item.uuid differs
between the files for all partitions so I will leave that out of this post.
The output of btrfs-show-super -fa for each device follows:
