Hi we are fairly new to ES and last night we lost connection to three of our nodes. Can anyone explain some of these errors/messages please.
EerrorClusterBlockException:[SERVICE_UNAVAILABLE]/state not recovered / initialized] :)status$^0
DEBUG action.admin.indicies.create connection exception while trying to forward request to master node.
We also use marvel
3) Error marvel_agent_exporter error sending data to [ http://0:0:0:0:0:0:0:0]:9200
Thanks for any help / advice.
