Read data from disk that was part of RAID1 array

Hi,

My setup:

Linux green 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:39:52 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 16.04.2 LTS

mdadm -V
mdadm - v3.3 - 3rd September 2013


I have only one disk from a RAID1 array and I would like to read data from
one of the partitions.  This there a way to mount this and read the data?

Thanks,
Pete
