Hi Everyone, I just upgrade our cluster to Luminous 12.2.7 and I delete a quite large pool that we had (120 TB). Our cluster is made of 14 Nodes with each composed of 12 OSDs (1 HDD -> 1 OSD), we have SDD for journal. After I deleted the large pool my cluster started to flapping on all OSDs. Osds are marked down and then marked up as follow : 2018-07-31 10:42:51.504319 mon.ceph_monitor01 [INF] osd.97 172.29.228.72:6800/95783 boot 2018-07-31 10:42:55.330993 mon.ceph_monitor01 [WRN] Health

it seems like a network issue but we haven’t change a thing on the network and this cluster has been okay for months. I can’t figure out what is happening at the moment, some help will be greatly appreciated ! Regards, |
