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.
