OK so I have a 2nd volume, which is only ever used to 'btrfs receive'
from the 1st volume. The 2nd volume is never persistently mounted. But
it too has bunches of these incorrect backref messages, where
btrfs-progs 4.6.1 comes up clean. A 3rd volume, is only ever used to
receive rsync from the 1st

Hi,
Thanks for your report.
I've sent a patch to btrfs community to fix this issue, currently it's
not merged.

In btrfs_async_reclaim_metadata_space(), we use ticket's address to
determine whether asynchronous metadata reclaim work is making progress.
ticket = list_first_entry(_info->tickets,
struct reserve_ticket, list);
if (last_ticket == ticket) {
Quite a common sense for any RAID-like multi-device setup, just in case.

For RAID5, 2 devices setup is just RAID1 with more overhead.
For RAID6, 3 devices setup is RAID1 with 3 copies, not what most user
want.
So warn user at mkfs time for such case, and add explain in man pages.

Is it worthwhile adding a note that RAID5 / RAID6 may very well eat your
data at this stage?
