Hi, I'm starting to experiment with iscsi based volumes and while this works fine so far I ran into a problem. When I add a LUN to a target and refresh tgtd all i/o to that target seems to hang for five seconds. This is obviously less than ideal if the plan is to use the target for lots of guests. There is also the possibility to create one target with one LUN for each guest disk but that sounds like a management nightmare and the libvirt pool functions become useless.

Is there a way to make this less intrusive? How do you guys cope with this issue?

Regards, Dennis
