I've run into a few issues as well activating OSDs on CentOS 7.
First, there's an issue with the version of parted in CentOS 7.2:
https://bugzilla.redhat.com/1339705
Secondly, the disks are now activated by udev. Instead of using
activate, use prepare
and udev handles the rest.
Third, this doesn't work well if you're also using LVM on your host
since for some reason
this causes udev to not send the necessary add/change events.
Hope this helps,
Ruben
