From mdadm.conf.5
The keywords are:
.TP
.B DEVICE
A
.B device
line lists the devices (whole devices or partitions) that might contain
a component of an MD array. When looking for the components of an
array,
.B mdadm
will scan these devices and no others.
^^^^^^^^^
Also,
.TP
.B devices=
The value is a comma separated list of device names. Precisely these
devices will be used to assemble the array. Note that the devices
listed there must also be listed on a DEVICE line.
You need to add
DEVICE /dev/sd[ab]
or similar to mdadm.conf
