Troubleshooting: Old index pages automatically removed after replication
Old index files are removed after replication. This behavior is enabled by interim fix JR55000, which is included in Feature Pack 7. The feature can be disabled by setting the keepIncompatibleIndex property to "true."
Solution
Following installation of Feature Pack 7 or interim fix JR55000, subordinate machines will delete
their old index files after replication. If you want to suppress this behavior, set the
keepIncompatibleIndex property to true in the
solrconfig.xml for the subordinate machine's search cores. Add the property to
the request handler section for the
subordinates.
<requestHandler name="/replication" class="com.ibm.commerce.foundation.internal.server.services.search.handler.solr.SolrSearchReplicationHandler">
<lst name="slave">
...
<str name="keepIncompatibleIndex">true</str>
</lst>
</requestHandler>
