Subject Missing shards/hash range
Date Tue, 10 Jan 2017 19:34:05 GMT

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,

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

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) ?
