Let me guess: You have version 0.90 superblock, and sdl1 covers the

sdl1 does cover the entire device, but I'm fairly certain I do not have
a 0.90 superblock (Unless 0.90 was the standard version for Linux 2.6
about two years ago.)
Unfortunately, I'm not sure how to get my current superblock version:
$ sudo mdadm --examine /dev/md2
mdadm: No md superblock detected on /dev/md2.
I find it curious that I can't detect the superblock for the MD device,
even though the device is up, active, and working.
Short term, change your mdadm.conf to only accept device names that end
with a digit. Like so:
DEVICE /dev/sd[a-z][1-9]
OK, I'll give that a whirl. For the record, it was DEVICE partitions
previously.
Then rebuild your initramfs to include the new mdadm.conf.
Long term, rebuild your array with v1.x metadata.
You know, I was hoping to be able to wait until btrfs handles RAID-6
(or "raid-z") arrays by the time I had to rebuild the array. I guess
I'm not that lucky.
