Hi all,

While I haven't gotten any "scrub already running" type errors any more, I do get one strange case of state misreport. When running scrub on /home (btrfs RAID10), after 3 of 4 drives have completed, the 4th drive (sdb) will report as interrupted, despite still running:

# btrfs scrub status -d /home
scrub status for 472c9290-3ff2-4096-9c47-0612d3a52cef
scrub device /dev/sda (id 1) history

	scrub started at Sat Nov 22 11:57:34 2014, interrupted after 3698 seconds, not running

	scrub started at Sat Nov 22 11:57:34 2014 and finished after 2994 seconds
	total bytes scrubbed: 252.85GiB with 0 errors

The funny thing is, the time will still update as the scrub keeps going:

# btrfs scrub status -d /home

	scrub started at Sat Nov 22 11:57:34 2014, interrupted after 4136 seconds, not running
								     ^^^^^^^^^^^^
	total bytes scrubbed: 239.44GiB with 0 errors

	scrub started at Sat Nov 22 11:57:34 2014 and finished after 2994 seconds
	total bytes scrubbed: 252.85GiB with 0 errors

This has happened a few times, and when sdb finally finishes, the status is then reported correctly as "finished":

# btrfs scrub status -d /home

I've got the exact same problem, with a 4 drive RAID1. kernel 3.18-git and btrfs tools-git, all built yesterday.

Not in my case; at least, nothing that made it into the syslog.
