Hello, The following is my config
Solr 5.5.0 on HDFS (SolrCloud of 25 nodes) collection with shards=20, maxShards per node=1, replicationFactor=1, autoAddReplicas=true The ingestion process had been working fine for the last 3 months. Yesterday, the ingestion process started throwing the following exceptions: SolrException: No active slice servicing hash code 7270a60c in DocCollection(xxxx) I can see that suddenly 2 shards missing. Solr Cloud UI says number of shards for the collection are 18. Somehow, shards have got deleted. The data is available on hdfs. Is there a way I can restart those shards on 2 of the hosts and provide a particular hash range(The hash ranges that are missing) ? Thanks!
