[ceph-users] Reper Ceph Cluster only OSDs intakt

Playing around with Ceph I did a Big mistake. My root filesystem uses snapshot and only excluding /home & /root. When I switched back to an older Snapshot  I noticed Ceph is complaining all OSDs are not working. How can I Fix this? Rebuild cluster and then add the OSDs back in? Is there a guide? Which folders had to be excluded for snapshotting not affecting Ceph?
