Subject: [BUG?] btrfs scrub -d doesn't scan all devices
Date: Sun, 27 Dec 2015 04:38:56 +0100	[thread overview]

Hey.

I've just noted the following behaviour:

# btrfs scrub start -Bdr /
scrub device /dev/sda2 (id 1) done
	scrub started at Sun Dec 27 01:59:05 2015 and finished after 00:04:04
	total bytes scrubbed: 29.39GiB with 0 errors
scrub device /dev/sdb2 (id 2) done
	scrub started at Sun Dec 27 01:59:05 2015 and finished after 00:04:08
	total bytes scrubbed: 29.39GiB with 0 errors

=> that works as expected

However:
# btrfs scrub start -Bdr /dev/disk/by-label/system
scrub device /dev/sdb2 (id 2) done
	scrub started at Sun Dec 27 01:53:18 2015 and finished after 00:04:01
	total bytes scrubbed: 29.37GiB with 0 errors
=> seems to scan only sdb2 (which is where /dev/disk/by-label/system points to)
   at least, no output is given for sda2


Cheers,
Chris.
