I'm running a three node cluster, and over the weekend one of the machines hosting one of the ES nodes failed. I restarted it this morning, but the cluster state remains red hours after restart, with the node seemingly refusing to allocate any shards, with the monitoring paging showing the implicated node allocating only 1 shard against the over 800 in the other 2. I'm at wits end, any help would be appreciated. I'm running ES 6.6.1.
The problem node is the second one in the list.
Please let me know what other info could be needed.
