But I'm not sure.
I'm fairly certain it's from the repair operation, the device didn't have any
single metadata before (and it still didn't really, notice that used=0.00B).
So my best guess is that it was allocated during the --repair.

I certainly didn't create them myself, the device has always had metadata=dup
(you can check previous threads of mine, which also contain "btrfs fi df"
output). So I don't think it has anything to do with the failures.

Again, I don't think it has anything to do with the single metadata. A "btrfs
balance start -mprofile=single" got rid of the (empty) single metadata blocks.
What I *can* say is that the error seems to be transient. For example, I ran
an rsync last night that failed with the same error as before. After
unmounting and mounting the FS again, I could run it to completion (and
verified some files).
Anyway, here's the whole log since this morning. I can't correlate individual
stack traces to specific actions any more, but the rough order of actions on
my part (not counting unmount/mount cycles, those are easy enough to find):
- backups from the home server run, then
- btrfs-cleaner drops old snapshots, after which
- I run rsync (which fails), then
- I run rsync again (which succeeds), then
- I run "balance start -mprofile=single", which succeeds (I might have run
this before rsync, I'm not sure), after which
- I start backups on my laptop (which fails after I finally went to bed, at
about 3:58).
After that I just try "btrbk -r run" a few times, which managed to transfer
the first two snapshots before failing.
