Ceph » devops

There should be a ceph-disk remove to cleanup an OSD and the associated device / directory. This is not something a system administrator would want to do on a production system because Ceph supports removing the device associated the OSD without the need to notify the cluster and it probably explains why it has not been implemented.
However, in the context of integration testing or debuging puppet, chef, etc. being able to reliably reset a device without nuking the machine is helpful.
Without explicit support from ceph-disk, it is possible but fragile because the logic to determine if a device contains a particular OSD file system is coded in ceph-disk and not easily accessible.
