Hi, I'm using Ceph on a 4-host cluster for a year now. I recently discovered the Ceph Dashboard :-) No I see that the Dashboard reports CephNodeNetworkPacketErrors >0.01% or >10 packets/s... Although all systems work great, I'm worried. 'ip -s link show eno5' results: 2: eno5: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000 link/ether 7a:3b:79:9c:f6:d1 brd ff:ff:ff:ff:ff:ff permaddr 5c:ba:2c:08:b3:90 RX: bytes packets errors dropped missed mcast 734153938129 645770129 20160 0 0 342301 TX: bytes packets errors dropped carrier collsns 1085134190597 923843839 0 0 0 0 altname enp178s0f0 So in average 0,0003% of RX packet errors! All the four hosts uses the same 10Gb HP switch. The hosts themselves are HP Proliant G10 servers. I would expect 0% packet loss... Anyway. Should I be worried about data consistency? Or can Ceph handle this amount of packet errors? Greetings, Dominique.
