Yeah, I think that it's a nice feature. You could add 'load balancing' to the above list. Redirecting intelligently would be nice. How tgtd talks to another component? IBM's tgt iSCSI cluster solution is on the top of a SAN FS so you want tgt to read a file? I suppose that DRBD's tgt iSCSI cluster solution doesn't use a SAN FS. So it might be better to use some protocols. http://www.linuxtag.org/2010/en/program/free-conference/popup/details.html?talkid=369 -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
