The problem turned out to be two fold. Firstly, Tomcat was caching an old version on the admin page (hiding the replication link and some other info) and secondly I had a mistake in some configuration meaning the indexes weren't building in the correct places. But it's sorted now and I have some lovely replication working with my two cores.
Thanks for your help Mark. -- View this message in context: http://www.nabble.com/Replication-In-1.4-tp24356158p24357821.html Sent from the Solr - User mailing list archive at Nabble.com.
