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.

1. EerrorClusterBlockException:[SERVICE\_UNAVAILABLE]/state not recovered / initialized] :)status$^0

2. 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.

You should really post the entire log, there should be more there that will help us.
