Just wondering if this was ever resolved ? I am seeing the exact same issue when I moved from Centos 6.5 firefly to Centos7 on giant release using “ceph-deploy
osd prepare . . . ” the script fails to umount and then posts a device is busy message. Details are below in yang bin18’s posting below. Ubuntu Trusty with giant seems OK. I have redeployed the cluster and also tried deploying on virtual machines as well
as physical ones. Setup is minimal 3 x OSD nodes with one monitor node.

Hi
You logs does not provides much information , if you are following any other documentation for Ceph , i would recommend you to follow official Ceph docs.
