+ <title>Permit attachments table to grow beyond 4GB</title>
+ <para>By default, MySQL will limit the size of a table
+ to 4GB. This limit is present even if the underlying filesystem
+ has no such limit or if you are using RAID. To set a higher
+ limit, follow these instructions.</para>
+ <para>Run the <filename>MySQL</filename> command-line client and
+ enter:</para>
+
+ <screen> <prompt>mysql&gt;</prompt> ALTER TABLE attachments
+ AVG_ROW_LENGTH=1000000, MAX_ROWS=20000;
+ </screen>
+ <para>The above command will change the limit to 20GB. Mysql will have
+ to make a temporary copy of your entire table to do this. Ideally,
+ you should do this when your attachments table is still small.</para>
