If a storage-node is reinstalled, either because it needs a newer OS or because the node moves from old to new infrastructure, there is no need to start with its OSD fresh. The OSD's can be reinstalled into the cluster if they have not been reformatted with the following steps:

1. Run "ceph-disk volume lvm list" to see which disks are recognized by ceph"chown" all the ceph disk's to be owned by the "ceph" user and the "ceph" groupverify thall all OSDs are recognized by ceph

2. Install the role role::storage on the new node
3. Create OSDs, typically 2 per device on a 2TB Drive. Details below
