linux 4.1.4 forced read-only during an rsync, complaining about lack
of space, with ~30TB free. Filesystem has 6 snapshots, basically 3
incremental rsync's of 2 different external filesystems. Not sure how
to proceed, balance -dusage=5 then try and remount, doesn't balance
need rw?

I can't help about your issue, but also I can't resist to ask: if I read correctly
the data you have 2x 30TB disks, and 2x 40TB disks. It is correct ?
Are physical disk or virtual ones ?

1.
We probably need to understand what kicked in readonly. is it
-28 (No space left) OR -5 (EIO).
2.
There are no media errors from the block layer, hope we are not
fabricating the EIO in the FS layer... thats wrong.
digging more.
Thanks, Anand

Thanks for looking, let me know if you need any other info. I haven't
touched the system yet, but it appears I'll need to unmount to btrfs
check or mount rw,recovery to try and get it working again. Who knows
what will happen then? I can leave it as if for a few days if it will
help any diagnosis. Thanks again.
