Something strange happened,
in my Solr 6.6.5 cloud (1 collection, 5 shards, 3 replica) the
leader is stuck on offline node for shard3.
I already tried setting property preferredLeader to true on the
active core_node5 and called REBALANCELEADERS but nothing happened.
In the response of REBALANCELEADERS was nothing about shard3.
It feels like it doesn't know anything about core_node5.
Any idea how to fix this?
