trouble mounting btrfs filesystem....

["Scott E. Blomquist" <sb@techsquare.com>]

Hi All,

Early this morning there was a power glitch that affected our system.

The second enclosure went offline but the file system stayed up for a
bit before rebooting and recovering the 2 missing arrays sdb1 and
sdc1.

When mounting we get....
