Hi
I have done this morning an upgrade of my elk stack, to 6.3.0 to 6.7.0
here the steps
disable shards allocation
update elasticserach
when the "active_shards_percent_as_number" was 50% (yellow state)
update logstash
update kibana
then I have problems
I have an error when I see the logs of kibana, I was thinking the problem was kibana but I think not.
In elasticsearch I have this :
[2019-04-15T11:39:55,167][WARN ][r.suppressed ] [prod-master-1] path: /.kibana_task_manager/_doc/_search, params: {ignore_unavailable=true, index=.kibana_task_manager, type=_doc}
org.elasticsearch.action.search.SearchPhaseExecutionException: all shards failed
the status is red
"cluster_name" : "logging-prod",
"status" : "red",
"timed_out" : false,
"number_of_nodes" : 4,
"number_of_data_nodes" : 2,
"active_primary_shards" : 1507,
"active_shards" : 1507,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 1511,
"delayed_unassigned_shards" : 0,
"number_of_pending_tasks" : 0,
"number_of_in_flight_fetch" : 0,
"task_max_waiting_in_queue_millis" : 0,
"active_shards_percent_as_number" : 49.93373094764745
I have 2 indices in red : ".kibana_task_manager" and ".kibana_7"
How I can fix this ?
Do I have to enable again shard allocation ?
