In particular, to get anything for your trouble, you will probably need to dump the database, drop it, shut down MySQL and switch it to innodb tablespace-per-file, turn it back on, and then reload the dump, as I recently had to. This way, at least, once you clean it up, you can do the same dump and reload procedure on only one table, not the whole shootin' match. Cheers, -- jra -- Jay R.

For removing those users, see http://www.mediawiki.org/wiki/Extension:User_Merge_and_Delete Also remember that due to the way mysql works, it may not release those 20GB back to the filesystem. ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
[Wikitech-l] cleaning database of spam
Hi, this is more related to mediawiki rather than wikimedia, but this list is being watched a bit more I guess. Is there any extension that allows permanent removal of deleted pages (or eventually selected deleted pages) from database and removal of blocked users from database? Imagine you have a mediawiki wiki that has 20 gb database, where 19.99gb of database is spam and indefinitely blocked users. I think lot of wikis has this problem, making extension to deal with this would be useful for many small wikis. What is exact procedure of properly removing page from database so that it doesn't break anything? What needs to be deleted and in which order? ___ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
