12:01 dhblaz I have a fuel 4.x cluster using ceph for swift, glance and cinder.  I would like to add several more slower disks to ceph and move swift and glance there.  Anyone have any advice on how to do this?
12:03 kaliya dhblaz: I suppose you should reconfigure ceph, glance and radosgw by hand after adding disks
12:13 syt joined #fuel
12:16 dhblaz joined #fuel
12:17 dhblaz kaliya: thanks; do you know of any good guides that show where all the configuration knobs are?  Even if is to bootstrap a new cluster instead of changing an old one
12:18 kaliya dhblaz: for bootstrapping a new cluster, you can follow the guide as usual http://docs.mirantis.com/openstack/fuel/fuel-5.1/user-guide.html and be careful in the Disk Configuration phase
12:18 syt joined #fuel
12:19 kaliya about your configuration knobs, you should look into /etc/cinder/cinder.conf on the controller(s), to which ceph configuration is binded to, and modify the ceph.conf accordingly with your new configuration
12:25 Dr_Drache hmmm
12:26 Dr_Drache that is a good question, how do slower discs affect a ceph cluster.
12:26 kaliya Dr_Drache: there is also the net speed, that can affect the cluster
12:27 Dr_Drache kaliya, true, and I'd love to be on 10G, but giga is all I have.
12:27 kaliya yop
12:27 Dr_Drache just a curiosity, nothing I can "do" about it
12:29 dhblaz joined #fuel
12:30 dhblaz thank you, kaliya
12:31 kaliya dhblaz: you're always welcome
12:31 * merdoc waits for infiniband arrive for ceph
12:31 kaliya merdoc: great, then we'll wait for a new post :)
12:31 merdoc kaliya: already start it (%
12:33 syt joined #fuel
12:33 Dr_Drache well, I guess I can bond some ports
12:34 merdoc at least you can try (%
12:35 * enik_ waits for mellanox 56Gbe arrive for ceph ;)
12:36 merdoc hehe. me too ((%
12:36 kaliya good enik_
12:37 enik_ I will start with two sx1012, good and cheap, what about you?
12:40 syt joined #fuel
12:44 merdoc 1 x sx1012

13:08 hyperbaba What cards are going into server for that switch ?
13:12 jaypipes joined #fuel
13:13 merdoc hyperbaba: smthg like that - http://www.mellanox.com/page/products_dyn?product_family=4&mtag=connect_x
13:25 shenderson joined #fuel
13:29 hyperbaba merdoc: so it's infiniband network, not ethernet?
13:33 merdoc you also may use ethernet on that hardware
13:34 hyperbaba merdoc: Switch? so i need some of their ethernet cards like Mellanox ConnectX-3 ?
13:37 merdoc hyperbaba: yes
13:44 enik_ the sx1012 is ethernet switch, you can buy infiniband gateway licence
13:49 hyperbaba enik_: So, is it supported in fuel in ethernet mode?
13:52 mattgriffin joined #fuel
13:54 enik_ I actually can't imagine using ceph over infiniband, merdoc: you will use infiniband on it? Isn't Ceph TCP/IP?
13:55 merdoc enik_: yep. at least I want to try. and maybe somethimes ceph anounce support of RDMA

14:29 Dr_Drache kaliya, this bug https://bugs.launchpad.net/fuel/+bug/1373096; could you explain it a bit?
14:35 enik_ merdoc: I thought about VMA Open Source, it could help https://code.google.com/p/libvma/
14:41 kaliya Dr_Drache: what's not clear? Does that bug affect you?
14:42 Dr_Drache I guess I don't understand what it fixes, is the way described the pre-fix?
14:44 merdoc enik_: intresting. I look on it
14:46 Dr_Drache kaliya; that looks ALOT like some of the issues merdoc and I were having
14:48 merdoc I'm not sure that it related. I use cloud-init for win images. And if I'm right - cfntools not fully supported right now
14:49 Dr_Drache merdoc?

16:39 neophy Hi All, I deployed 4 node (controller, compute, storage, mongodb) openstack using Fuel 5.1. It seems "br-ex" interface missing in  compute, storage, mongodb nodes. I am not able to ping compute public from controller.
16:42 neophy any help?
16:55 ArminderS- joined #fuel
17:04 stamak joined #fuel
17:13 mpetason neophy : were you able to run network verify before deployment? did it recognize any issues?
17:14 mpetason neophy : also is this Ubuntu, and did you restart the nodes after the deployment finished? or do you see any errors in dmesg or /var/log/messages regarding bringing up eth0 or the bridge?
17:15 neophy mpetason: No I am not facing any issue. It is CentOS. I have not restarted after deployment
17:17 MiroslavAnashkin neophy: Do you use Neutron or Nova-Network?
17:17 neophy Neutron with VLAN
17:17 neophy MiroslavAnashkin:Neutron with VLAN
17:18 MiroslavAnashkin Then no public addresses should be on compute, storage and mongoDB nodes
17:18 neophy MiroslavAnashkin: there no such file /etc/sysconfig/network-scripts/ifcfg-br-ex
17:20 neophy MiroslavAnashkin: how do I create br-ex in compute, storage and mongoDB nodes?
17:20 MiroslavAnashkin Yes, no access to the external networks from nodes. All the access possible via Neutron server.
17:21 neophy MiroslavAnashkin: But it will automatically create br-ex in all the nodes in Fuel 5.0
17:21 MiroslavAnashkin Yes, and never used it. It was a remnant from Nova-Network times, actually a bug.
17:23 Dr_Drache what about the option in fuel to assign external network to all nodes?
17:23 Dr_Drache is that part of the "bug"?
17:24 MiroslavAnashkin https://bugs.launchpad.net/fuel/+bug/1272349
17:26 Dr_Drache MiroslavAnashkin. thanks sir
17:26 jobewan joined #fuel
17:26 MiroslavAnashkin NP
17:27 Dr_Drache MiroslavAnashkin, to get this fix : https://bugs.launchpad.net/fuel/+bug/1373096 i'd have to reinstall a 5.1.1 build?
17:29 MiroslavAnashkin Dr_Drache: No. You may apply the patch file to master node or set the correct glance_api version on the already deployed nodes
17:31 Dr_Drache MiroslavAnashkin, ahhh, didn't think that was a patchable fix, just a precompiled fix
17:32 MiroslavAnashkin Download this patch https://drive.google.com/file/d/0B4szgxpvz2aCZ2pjRVBpUjZkb3c/view?usp=sharing
17:32 adanin joined #fuel
17:33 MiroslavAnashkin Place it to master node to, say /root/ dir
17:33 MiroslavAnashkin # `yum install patch`
17:33 MiroslavAnashkin # `cd /etc/puppet/modules/`
17:33 MiroslavAnashkin # `patch -p1 < /root/glance_RBD_backend.patch`
17:33 mattgriffin joined #fuel
17:34 Dr_Drache and... done
17:34 Dr_Drache lol
17:35 Dr_Drache why do I always forget about patch... lol
17:37 Dr_Drache MiroslavAnashkin; any caches that need cleared?
17:37 MiroslavAnashkin On the already deployed cinder nodes or controllers - simply edit /etc/cinder/cinder.conf , find `glance_api_version` parameter and change it to `glance_api_version=2`
17:38 Dr_Drache no cinder/ceph nodes.
17:38 Dr_Drache deleted that evn
17:40 MiroslavAnashkin It may be on controllers
17:41 Dr_Drache I mean, I do not have a deployed enviroment.
17:42 MiroslavAnashkin Ah, then no more actions necessary. New envs should get correct glance_api_version setting on deployment
17:42 ddmitriev1 joined #fuel
17:42 Dr_Drache ok, going to do that here in a few min

20:51 championofcyrodi :)
20:56 championofcyrodi got a new job, trying to consolidate their 3 dev clouds running on VMware ESX and libvirtKVM a with custom network configurations in to openstack icehouse via fuel's environment configuration services.  fuel provides everything we want, but its a beast of a software stack, so i may have a lot of questions in the future.  just ignore me if i'm being too verbose ;)
20:56 xarses championofcyrodi: sounds fun
