... but you can't use a DirectoryStorage replica as a "hot" or "warm" backup. DirectoryStorage replicas are pulled from the master storage, and no storage process can be using the replica storage while this pull is happening - not even in read-only mode. This is documented at http://dirstorage.sourceforge.net/replica.html For more background discussion, see these threads - why hot failover won't work: http://sourceforge.net/mailarchive/forum.php?thread_id=4906719&forum_id=9987 some talk about cold failover: http://sourceforge.net/mailarchive/forum.php?thread_id=7828511&forum_id=9987 -- Paul Winkler http://www.slinkp.com _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
