[ceph-users] heartbeat_check failures

Hey guys, Today I noticed when adding new monitors to the cluster that two OSD servers couldn't talk to each other for some reason. I am not sure if adding the monitors caused this issue or whether the issue was always there but adding the monitor showed it. After removing the new monitor the

[ceph-users] Diagnosing slow requests

Hey guys, I'm running into an issue with my cluster during high activity. I have two SSD cache servers (2 SSDs for journals, 7 SSDs for data) with 2x10Gbit bonded each and a six OSD nodes with a 10Gbit public and 10Gbit cluster network for the erasure pool (10x3TB without separate journal). This
