Perquisites
Before you start the upgrade, you must ensure that the Elasticsearch cluster is in a 'green' state.
To validate the state, log into one of the hosts that have the squirro-storage-node package installed and run the following command:
| Code Block |
|---|
curl -XGET 'http://localhost:9200/_cluster/health?pretty=true' |
The output looks like this:
| Code Block | ||||
|---|---|---|---|---|
| ||||
{
"cluster_name" : "squirro-26aa394e-56ee-4274-b094-5075bb94d892",
"status" : "green",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 14,
"active_shards" : 14,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 0,
"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" : 100.0
} |
Check for the status on line 3. e.g. in this case:
| Code Block |
|---|
"status": "green" |
| Warning |
|---|
Do not proceed with the upgrade if the state is yellow or red. |
