Mike Drob commented on SOLR-15288:
----------------------------------
Is this safe for a bug fix release? I almost feel like PRS needs to marinate on
main before we bother trying to back port all of the stability fixes to it.
> PRS replicas stay DOWN after a new node is restarted
> ----------------------------------------------------
>
> Key: SOLR-15288
> URL: https://issues.apache.org/jira/browse/SOLR-15288
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: 8.8.1
> Reporter: Ishan Chattopadhyaya
> Priority: Critical
>
> 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.
