I seem to have it a deadlock trying out btrfs send & receive. Now I haven't used btrfs send & receive much, so don't have much experience with them. Anyways, bug report and stack traces: https://bugzilla.kernel.org/show_bug.cgi?id=202383 Seems like the receive is hung as well as several kworkers. It's about 1.2TB into a 9TB or so transfer onto a brand new pretty empty fs. This is just a btrfs send snapshot, not an incremental. That was supposed to come next. If this was an rsync based backup I'd just kill the rsync process and restart it, not sure if there's a way to restart a btrfs send receive, or if I'd have to delete the partially created snapshot on the destination and restart the send. I guess I could just use rsync to finish the copy of the initial snapshot as well before using send | receive for the incrementals. Thoughts and options would be appreciated, thanks. -Eli
