I'm given to understand that this is the right place to report a

problem, I apologise if not :-(
I have been using my router as a simple NFS NAS for around 2 years
with an ext3 formatted 2 TB Western Digital 2.5" USB Passport disk. I
have been slowly moving to BTRFS and thought it about time to convert
this disk too but unfortunately BTRFS is unreliable on my router :-(.
It doesn't take long for an error to happen causing a 'ro' remount.
However the disk is unreadable after the remount, both for NFS and
locally. Rebooting the router seems to be the only way to access the
disk again.
I also have a 1 GB swap partition on the disk although swap doesn't
appear to be a factor as the problem occurs whether or not swap is
enabled (this report is without swap).
I used my laptop to convert the fs to btrfs, not my router. My laptop
has Fedora 21 with 3.18 kernel and tools. No problems are found when
I
use my laptop to check and scrub the disk (i.e. with the disk
connected directly to my laptop).
You have great timing, there are two reports of a very similar abort
with 4.0-rc5, but your report makes it clear these are not a regression
from 4.0-rc4.
Are you able to run btrfsck on this filesystem? I'd like to check for
metadata inconsistencies.
