Perhaps this wasn't clear from my original message, but I'm not using btrfs'
RAID or lvm-like capabilities. The filesystem is on an LVM logical volume,
with the actual underlying storage being an 8-disk RAID-6 array (mdadm array).
So the stack is:
vanilla btrfs filesystem (not using subvolumes, btrfs' multiple device
support or any other advanced features)
LVM logical volume
LVM volume group
LVM physical volume
md_crypt / LUKS encrypted volume
mdadm RAID-6 array
8 x SATA disks

Okay:

This fails with `btrfs: unknown token 'show'`.

After mounting the filesystem read-only, the following ends up in the syslog:
[13333.117462] Btrfs loaded
[13333.157078] device label bigbackup devid 1 transid 5249
/dev/mapper/extbackup-bigbackup
[13333.158445] btrfs: disk space caching is enabled
That's the only btrfs-related info that gets logged.

As I say, it's 8 disks (yes, SATA). What info exactly do you want about the
disks and ports? The log is quite noisy because these are behind SATA port
multipliers, and there are a bunch of other SATA drives in the system. But if
I filter out all the extra stuff, then when I power up the port-multiplier
boxes that the disks are in, what's logged is 126 lines (much of it garbage
from not all possible multiplier ports being in use), log attached.
The 8 disks are, as you can see, all identical Seagate units:
ATA-8: ST3000DM001-1E6166, CC45, max UDMA/133

Btrfs v0.20-rc1-358-g194aa4a-dirty
That's what I get when I build from the git repository at
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git
git insists I'm fully up to date, though the last time I pulled before today
was over a month ago.
