Hi Robin,

I removed misc: ignore some unusable block devices 9c5eaeccb807d103884f46d174798dd982092696 from the openstack branch because it fails on CentOS 7 with
the following. Could you please make a new pull request with it so we can keep testing it there ?

Thanks !

Will do, but I wonder how you managed to get a return code of 2 from it;
as that should be device-does-not-exist.

IIRC that happens when blkid fails to retrieve information. I found blkid to be generally faster and less reliable than sgdisk -i 1 /dev/sdd for the purpose of getting partition information. For ceph-disk we chose reliability over speed. That being said I've not investigated the real reason why blkid returns -2.
