First unmount /dev/md0s1a, or the device /dev/md0s1 will be in use, and
opening it for read/write (as bsdlabel probably does) will fail.
Alternatively, you can turn on the "footshooting" debug flag in geom:
Protection mechanisms in the geom(4) subsystem might prevent boot0cfg
from being able to update the MBR on a mounted disk. Instructions for
temporarily disabling these protection mechanisms can be found in the
geom(4) manpage. Specifically, do a
sysctl kern.geom.debugflags=0x10
to allow writing to the MBR, and restore it to 0 afterwards.
and try again. This may not work as expected though. :)
