Trying to image the file system in bug 92641, but the command hangs.

[root@f21w2 ~]# btrfs-image -c9 -t2 -s /dev/sdb btrfs.image
warning, device 2 is missing
warning devid 2 not found already

top reports btrfs-image process using 100% CPU, decided to kill it after 1/2 hour with no change in image file size.
