    <p>I have a 5-core solr 1.4 master that is replicated to another 5-core solr using solr replication as described <a href="http://wiki.apache.org/solr/SolrReplication" rel="nofollow noreferrer">here</a>. All writes are done against the master and replicated to the slave intermittently. This is done using the following sequence:</p> <ol> <li>Commit on each master core</li> <li>Replicate on each slave core</li> <li>Optimize on each slave core</li> <li>Commit on each slave core</li> </ol> <p>The problem I am having is that the slave seems to be keeping around old index files and taking up ever more disk space. For example, after 3 replications, the master core data directory looks like this:</p> <pre><code>$ du -sh * 145M index </code></pre> <p>But the data directory on the slave of the same core looks like this:</p> <pre><code>$ du -sh * 300M index 144M index.20100621042048 145M index.20100629035801 4.0K index.properties 4.0K replication.properties </code></pre> <p>Here's the contents of index.properties:</p> <pre><code>#index properties #Tue Jun 29 15:58:13 CDT 2010 index=index.20100629035801 </code></pre> <p>And replication.properties:</p> <pre><code>#Replication details #Tue Jun 29 15:58:13 CDT 2010 replicationFailedAtList=1277155032914 previousCycleTimeInSeconds=12 timesFailed=1 indexReplicatedAtList=1277845093709,1277155253911,1277155032914 indexReplicatedAt=1277845093709 replicationFailedAt=1277155032914 lastCycleBytesDownloaded=150616512 timesIndexReplicated=3 </code></pre> <p>The solrconfig.xml for this slave contains the default deletion policy:</p> <pre><code>[...] &lt;mainIndex&gt; &lt;unlockOnStartup&gt;false&lt;/unlockOnStartup&gt; &lt;reopenReaders&gt;true&lt;/reopenReaders&gt; &lt;deletionPolicy class="solr.SolrDeletionPolicy"&gt; &lt;str name="maxCommitsToKeep"&gt;1&lt;/str&gt; &lt;str name="maxOptimizedCommitsToKeep"&gt;0&lt;/str&gt; &lt;/deletionPolicy&gt; &lt;/mainIndex&gt; [...] </code></pre> <p>What am I missing?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
