Under the last several kernels versions (4.6 and I believe 4.4 and, 4.5) btrfs
scrub aborts before completing.
I can't reproduce this with btrfs-progs 4.5.2 and kernel 4.6.0.
I think the bigger issue is the lack of information why a scrub is aborted.
Thanks for checking into this Chris.
Any advice on how to get some more information out of the scrub process?
Next you need to find out why this one device has so many errors. Put the
output from smartctl -x /dev/sdb somewhere, maybe even attach it to the bug
report since it's somewhat related. Either that device is simply unreliable, or
you've got a bad cable connection.
The device is okay. The errors were caused by me running it for a period with
only one of the devices present.
In more detail. My desktop has a BTRFS RAID 1 setup. I needed to access to it
on the road, so I just shut the desktop down, grabbed one of the drives, and
used it in my laptop in degraded mode.
When I got back I recombined them (the one I left in my office was never booted
by itself) and started a scrub. That is when I discovered scrub aborted on
newer kernels but completed okay on older ones.
Cheers! -Tyson
