Sorry, I was in another meeting. 14:46:18 <yangyapeng> hello slashme 14:46:36 <dstepanenko> yangyapeng: ok, so as far as I understood, we should get real size of disk and use it instead of virtual size. Is that right? 14:46:41 <dstepanenko> slashme: hey 14:46:41 <slashme> I'll take some time to review the rsync patch an the ssh patch next week. 14:47:23 <dstepanenko> slashme: thanks! 14:47:29 <raliev> slashme, hey, thank you :) 14:47:35 <yangyapeng> dstepanenko: yeah, This is a different backup local, 14:48:35 <slashme> As szaher said for the ssh one. We need to find a way to do the copy without loading the full file in memory 14:48:37 <yangyapeng> dstepanenko: maybe, we can have a real size to transfer 14:49:16 <dstepanenko> slashme: he pointed to code which was copying metadata file 14:49:21 <dstepanenko> which itsn't that big 14:49:23 <yangyapeng> slashme: yeah. but it have other question, if we have a raw disk to transfer 14:51:14 <slashme> dstepanenko: you are right :) 14:51:37 <dstepanenko> slashme: :) 14:53:02 <dstepanenko> yangyapeng: correct me, if I'm wrong, backup to local also face the same problem, doesn't it? So, we need to enhance it for both backup mods 14:53:48 <dstepanenko> I mean - for local and ssh backup 14:57:20 <yangyapeng> dstepanenko: yeah, 14:58:31 <yangyapeng> dstepanenko: it have a big space to used,but if we use swift(ceph), it should be raw, so wether we should reslove it 14:58:36 <dstepanenko> yangyapeng: so, let's move it into separate feature and cover both cases. Probably, there are some cases which we forget about 14:59:55 <yangyapeng> dstepanenko: :) 15:00:24 <slashme> Good. 15:00:31 <slashme> It's time. 15:00:34 <yangyapeng> we can have more discuss in irc #openstack-freezer 15:00:53 <yangyapeng> thank you everyone 15:00:54 <slashme> yangyapeng: can you close the meeting please 15:00:55 * bswartz waves to freezer team 15:01:04 <yangyapeng> #endmeeting
