We are running 17.10 and just recently had a power failure on a small 2 node cluster.
After power has been restored the servers tried to recover but failed. Now we are left with:
cluster_name: dffess status: red timed_out: false number_of_nodes: 2 number_of_data_nodes: 2 active_primary_shards: 0 active_shards: 0 relocating_shards: 0 initializing_shards: 0 unassigned_shards: 28
There are 28 unassigned_shards which can not be assigned anymore?
We have restarted the node / entire cluster many times without success.
There seems to be nothing we can do to make ElasticSearch start recovery on those shards again.
