HI Guys, Our ceph cluster seems to be compromised by rootkit attack. It has 5 mon including one mgr and 7 osd nodes. We will need to reformat and reinstall OS on ceph mgr node and 2 ceph mon nodes. 2 mon nodes and 7 osd nodes are safe. Ceph health status is showing ok. And the cluster is still working but very slow. Please let me know how to proceed to have minimal disruption to the users and without any data loss Thanks, Gagan
