    [ https://issues.apache.org/jira/browse/SOLR-15288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17308740#comment-17308740 ] 

Ishan Chattopadhyaya commented on SOLR-15288:
---------------------------------------------

This is a major problem for those who want to adopt PRS, and warrants a 8.8.2 bugfix release. Both [~noble.paul] and I are out on vacation and shall both be back after Holi to tackle this.

> After a PRS collection is created using a single node cluster, and a new node is added and a replica for that collection is placed on the new node, restarting that new node causes problems with replica states.
> Reproduce script:
> {code}
> # Start a fresh ZK on 2181
> # docker container prune -f && docker run -it -p 2181:2181 --name=zk1 -h zk1 zookeeper:3.5.6
> rm -rf server/logs/*
> bin/solr stop -all
> rm -rf server/solr/mycoll_shard1_replica_n1/ server/solr/mycoll_shard1_replica_n3/
> bin/solr -c -p 9000 -z localhost:2181
> curl "http://localhost:9000/solr/admin/collections?action=CREATE&name=mycoll&numShards=1&perReplicaState=true"
> bin/solr -c -p 9001 -z localhost:2181
> curl "http://localhost:9000/solr/admin/collections?action=ADDREPLICA&collection=mycoll&shard=shard1"
> bin/solr stop -p 9001
> bin/solr -c -p 9001 -z localhost:2181
> {code}
> Two problems:
> 1. Now look at the two replicas, both are down. 
> 2. Also, as [~hitesh.khamesra] found out, the second replica stays ACTIVE (not DOWN) after the second node (9001) is stopped.
