And my Node Problem detector is showing {*reason*="Ext4Error"}
more than 1 thousand appears on one node
but in UI everything works fine (all is on green)
Grafana also working as well
I have 5 nodes let's say
node1, node2, node3, node4, node5
grafana is working on node3 and the data replicas is on node4 and node5
Mayby something is missing?Root causes
2. The network bandwidth is not sufficient. Normally 1Gbps network will only able to serve 3 volumes if all of those volumes are running a high intensive workloadMy Bandwith is
930 Mbits/sec
between nodes
And
node1 have 0 replicas (master)
node2 have 5 replicas of diffrent pvc
node3 have 6 replicas
node4 have 3 replicas
node5 have 3 replicas
and number of volume is 6 (one of the biggest pvc volume is 15Gi)
It can make a issue in my case?icy-agency-38675
