Opensearch pods do not start:

If the following message appears in the Opensearch pod logs, the vm.max_map_count:

ERROR: [1] bootstrap checks failed

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]


On all control-plane and worker nodes the line "vm.max_map_count=262144" must be added to the file "/etc/sysctl.conf".


After that the following command must be executed in the console on all control-plane and worker nodes: sysctl -p


Finally, the Opensearch pods must be restarted.
