Force a fetchindex on slave from master command: http://slave_host:port/solr/replication?command=fetchindex - from http://wiki.apache.org/solr/SolrReplication
The above command will download the whole index from master to slave, there are configuration options in solr to make this problem happen less often (allowing it to recover from new documents added and only send the changes with a wider gap) - but I cant remember what those were. -----Original Message----- From: Andrew Butkus [mailto:andrew.but...@c6-intelligence.com] Sent: 05 March 2015 14:42 To: <solr-user@lucene.apache.org> Subject: Re: Solrcloud Index corruption We had a similar issue, when this happened we did a fetch index on each core out of sync to put them back right again Sent from my iPhone > On 5 Mar 2015, at 14:40, Martin de Vries <mar...@downnotifier.com> wrote: > > Hi, > > We have index corruption on some cores on our Solrcloud running version > 4.8.1.
