[ceph-users] Re: OSD heartbeat failure

Hello Neil, You should never never never do a snapshot on a ceph cluster (in a vm perspective as you say). I have my ceph cluster in virtualbox but i only shutdown my cluster with commands like ceph osd noout, norebalance, pause etc. Regarding the osd heartbeat, here is some articles that might help you. https://ceph.io/planet/dealing-with-some-osd-timeouts/ https://access.redhat.com/solutions/2127471 You might want to adjust any timers if you want but do make sure there is connectivity between the osd nodes and also you may see these heartbeats during scrubbing as well.
