Dear btrfs team,
I send a kernel crash report which I have observed recently during btrfs scrub.
It looks like scrub itself has completed without errors.
# btrfs scrub status /home

scrub started at Mon Jan 1 06:52:01 2018 and finished after 00:30:47

It's not a kernel crash (if I didn't miss anything), but just kernel
warning.
The warning is caused by the fact that your fs (mostly created by old
mkfs.btrfs) has device with unaligned size.
You could either resize the device down a little (e.g. -4K) and newer
kernel (the one you're using should be new enough) could handle it well.
Or you could update your btrfs-progs (I assume you're using Arch, which
is already shipping btrfs-progs v4.14) and use "btrfs rescue
fix-device-size" to fix other device related problems offline.
(Not only the warning, but also potential superblock size mismatch)
Thanks,
Qu

Thanks for reply!
Why couldn't a warning message be issued as one-liner, e.g. with proper
description and without scaring stack trace?
btrfs /dev/sda1 warning: device size is not aligned with FS (mostly created by old mkfs.btrfs), see https://btrfs.wiki.kernel.org/index.php/FAQ#...

With best regards,

Because we're using WARN_ON() and the backtrace is in fact very useful
for developers to locate the problem.
For one-line message, the problem is we don't know who caused the
problem if there are multiple callers.
But since the cause of the problem is located, one-line output seems better.
Thanks,
Qu
