Thank you Erick Erickson and Kevin Risden, I upgraded to 7.7.1 and the problem has disappeared.
However: After upgrading, Solr admin in IE11 stopped working correctly. I switched to Google Chrome and it works. -----Original Message----- From: Erick Erickson <erickerick...@gmail.com> Sent: Friday, March 08, 2019 3:14 PM To: solr-user@lucene.apache.org Subject: Re: All replicas created on the same node Sounds like SOLR-13248. You should be able to cure this by setting the clusterproperty useLegacyReplicaAssignment, something like: curl -X POST -H 'Content-type:application/json' --data-binary ' { "set-obj-property": { "defaults" : { "cluster": { "useLegacyReplicaAssignment":true } } } }' http://$SOLR_HOST:$SOLR_PORT/api/cluster or upgrde to Solr 7.7.1. > On Mar 8, 2019, at 12:04 PM, levtannen <lev.tan...@usdoj.gov> wrote: > > Hi community, > I have solr 7.6 running on three nodes with about 400 collections with > one shard and 3 replicas per collection.
