vodanh86as i read about networing options in cactus doc : "In both flat modes, the network nodes do not act as a default gateway. Instances are given public IP addresses."01:22

vodanh86as I understand, in FLATDHCP mode, nova-network host ac as gateway, but how about FLAT mode?01:31
dysingerquestion: if I have a client that wants to hack on openstack code & they want to override some of swifts code, can they just deploy a python egg that would over-ride ubuntu package python code for swift?  Is it possible to just put the egg code in the path first before starting services ?  I am no python class-loader expert.01:32

notmynamedysinger: that should work. depending on what part of swift you want to override, you may simply be able to do it with your own middleware02:16
dysingernotmyname: thanks02:17
notmynamedysinger: but essentially, Python uses a path system like a shell and the first package it finds is the one it uses. the shell var to control this is PYTHONPATH02:17
johnpuris anyone running swift on 11.04? i am seeing some wierd xfs timeout errors...02:17
notmynamejohnpur: sorry I didn't answer you earlier. I don't know. we're using LTS02:18
dysingernotmyname: sounds like ruby, java, erlang, etc - it's all the same - first code in the path that matches wins02:18
notmynamedysinger: indeed02:18
johnpurnotmyname: I know! Did you find any XFS wirdness in getting the LTS version to work?02:19
johnpurnotmyname: the system is throwing timeount eerors on the sync process02:19
notmynamejohnpur: can you paste a traceback?02:20
johnpurnotmyname: not tonight, but soon02:20
notmynamejohnpur: but you're sure it's xfs?02:20
notmyname(ie not swift throwing the timeouts)02:21
johnpurthe error is: INFO: task xfssyncd/sdb2/6694 blocked for more than 120 seconds02:22
notmynamejohnpur: not sure. perhaps tomorrow we can bug letterj or pandemicsyn about it. btw, cw is also an expert on xfs :-)02:23
johnpurnotmyname: sounds good... i am wondering if xfs is sensitive to ubuntu versions... a lot of testing has been done on 10.04, not so much on 11.04...02:25

deepestand I want to use this server with solaris for nova-volume04:31
deepestwhat do I need to do?04:31
deepestand How can I do this job?04:32
kpeppledeepest: there is a SolarisISCSDriver in nova/volume/san.py that should help you. follow the directions in that file at line 144.04:33
deepestwhere can I see this file?04:34
kpeppledeepest: if you've installed from the source code, it's in trunk/nova/volume/san.py.  If you installed from package, it's probably where ever they installed the nova egg.04:35

deepestand now, if I want to use solaris then where can I install nova-volume?04:46
deepestin solaris server or in any host04:46
kpeppledeepest: i think you need to install it on another host (it uses ssh to contact the solaris iSCSI server)04:47
deepestand about Solaris Server04:48
deepestdo they need LVM to contact to nova-volume?04:48
kpeppledeepest: i don't think they need LVM04:48

deepestI read the tutorial file " compute adminguide cactus" and saw some information about LVM04:53
kpeppledeepest: the best tutorial i've read is http://www.dubsquared.com/?p=120 but that does not talk about Solaris04:53
deepestand they said that "To set up Compute to use volumes, ensure that nova-volume is installed along with lvm2."04:53
deepestthanks04:54
deepestbut I think, the firstly I must understand deeply in Storage04:54
deepestand after that I can change to Solaris04:55
kpeppledeepest: yes, it is best to start with something easier like linux then try solaris04:55
deepestyep04:56

nagyzI have a two-compute node setup. At the first node, everything is OK, but at the second, the ubuntu cloud image behaves like it hasn't got an IP. however, both in db and in the tools, I see the assigned IP. I'm using flat manager.08:06
nagyzany ideas?08:06
matttnope, but i have a question ... w/ a two compute-node setup, does each compute node need to run nova-compute?08:12
nagyzyes08:12
nagyznova-compute IS the compute component.08:12
matttyeah, that's what i figured, until i read some answers saying that nova-compute does not need to run on the dom0, which threw me off.08:12
nagyzI don't know about Xen, but I guess it should be the same with KVM: it should run on each compute node.08:13

nagyzdoude_, I'm trying to set up my second compute node. did you have any problems with networking?08:57
doude_it's strange, I get this error only with this node. With others nodes, it works nicely. I use he same version (rev 1244) on all nodes08:59

nagyzthe VM starts up, the interfaces file looks good, populated with the IP09:01
nagyzhowever, the VM stops booting and starts throwing metadata timeout messages09:01

nagyzI've added it per instructions of the linked docs09:13

I put into nova conf these lines "--glance_host=172.16.8.203 --image_service=nova.image.glance.GlanceImageService", and on first machine it works as intented, but on second `euca-describe-images` says "no route to host"10:00
KAMah, I meant I'm launching this server ( instance ) for somebody else, then while he is working I want to execute some scripts on the background.10:00
KAMWithout me actually accessing the machine.10:00
sorenKAM: So why don't you?10:00
sorenAha!10:00
KAMs/machine/server10:00
sorenOk, so I'll go back to my original answer: Puppet.10:01
Deirz-but `wget 172.16.8.203:9191/images -q -O -`, invoked on second machine, shows me a list of images10:02
KAMsoren: Yup, but that requires other software to be installed on the server. Something that actually listens puppet, no ?10:02
dsockwellpuppet connects out10:03
dsockwellKAM: if you were using openvz you might use vzctl to inject commands/processes into the machine10:03
dsockwellwhat's your goal? what do these scripts do?10:03
sorenKAM: Yes.10:03
sorenKAM: Nothing you've said suggests that this is a problem.10:04
sorenKAM: Erl, well, as dsockwell says, puppet connects out (usually). But it needs to run inside the vm.10:04
dsockwellyou could put a key into /root/.ssh/authorized_keys to allow yourself root access to the vm10:05
dsockwellthat would be part of the image file, unless that's particularly forbidden10:05
KAMdsockwell: Just executing monitoring scripts based on what the user is doing.10:05
dsockwellyou could inject the scripts into the image using init.d or rc.local10:06
dsockwellhey, does any part of a typical compute node require direct access to the database that nova-api keeps?10:08
dsockwellthat would be a silly thing to allow, wouldn't it?10:08

*** cp16net_ has joined #openstack14:31
kbringardit looks like bridge_interface needs to be set in the DB14:31
kbringardif you're running the latest trunk14:31

nagyzno, it's the bundled version in natty14:31
kbringardit looks like it's replaced vlan_interface14:31
jatsrtupdate bridge_interface14:31
nagyzbut it's not trunk. :)14:31
jatsrteasier that deleting and recreating all of your networks14:31
nagyzI use the same nova.conf in both compute nodes, just changed myip14:31
kbringardnagyz: ah... well, if you see bridge_interface in the DB i'd make sure it's populated14:32
nagyzeven on cactus?14:32
kbringardI'm not sure when it was introduced14:32
kbringardoh14:32
kbringardwell14:32
kbringardthen14:32
kbringardhaha14:32
kbringardno idea14:32
nagyzI had a look at the network table, and it has a "bridge" field14:32
jatsrthas anyone tried to pause/suspend VMs14:32
kbringardjatsrt: I have not14:32
jatsrtnagyz: not the same issue then14:33
kbringardwe mostly use the ec2 api14:33
jatsrtrecently they added a bridge_interface field too14:33
nagyzis there an easy way to check if both machines see each other thru the vlan?14:33
nagyzjust for testing can I add a random IP to br100?14:33
alexn65hi! can someone tell me about network, bridging and public IPs? For now in flat network mode instance have private net ip and do not see inet14:33
nagyztwo from the same subnet of course on the two hosts14:33
jatsrtkbringard: just thinking if I have to reboot a compute node for maintenance and don't want to live migrate I could suspend unsuspend them14:33
nagyzwell, br100 on the host that has nova-network already has 10.0.0.114:34
kbringardjatsrt: yea, it seems like a good feature, I've just not played with it14:34
kbringardnagyz: I'd bring up a new interface14:34
mpatelkbringard: now can't reach through the public IP on eth0 interface after restarting the nova-network14:34
kbringardlike, eth1:1 or something14:34
nagyzthat won't be part of the vlan14:34
kbringardif eth1 is tagged14:34
kbringardit should work14:34
kbringardthat's how I test14:35
nagyzI did add 9.9.9.1 to eth1:1 on the second compute node14:35
nagyzand 9.9.9.2 to the first compute node on eth1:114:35
nagyzand they can ping each other14:36
kbringardand if you cat /proc/net/vlan/config you see that eth1 is tagged with the correct vlan on both nodes?14:36
kbringardah, then that would indicate that the vlan tagging is working properly14:36

devcamcarvishy: sweet stuff20:03
bastichelaaryes20:03
devcamcarvishy: is vlan support in scope?20:03
vishydevcamcar: vlan mode should work but it is costly20:03
devcamcarvishy: how so?20:04
vishybastichelaar: thanks for finding that issue, i think it needs to be reworked a little bit but that is close to the right fix20:04
devcamcarvishy: does br100 go away?20:04
vishyin vlan mode, it will create all vlans on all hosts20:04
vishyand every host needs an ip in every project network, so it burns a lot of ips20:05
vishynot that big of a deal for a 12 node cluster20:05
bastichelaarvishy: thanks. I'm not a good programmer, but it seems that the LXC stuff is really basic and not used a lot, right?20:06
vishybut for a 255+ that is killing a /24 for every project20:06
WormManI had no problem not giving my compute nodes IPs in the added network20:06
WormManbut I didn't try VLAN20:06

vishybastichelaar: most people using LXC are not using cow images i think20:06
vishyWormMan: true in the current code, we're talking about the ha-net branch20:06
vishyusing multi_host networks20:07
bastichelaar vishy: what are they using then? I'm quite new in this area...20:08
*** tonycampbell has joined #openstack20:08
heckjvishy: where do the floating IPs get allocated in the ha-net branch? Spread around the various node, or collocated with the VMs?20:09
vishycollocated20:09
vishyfloating ips are allocated to the host that the vm is on20:10
vishyand natted to the fixed_ip20:10
vishybastichelaar: --nouse_cow_images20:10
*** tonycampbell is now known as tcampbell20:10
vishywill use losetup mounts instead of nbd20:10
vishyshould be a bit faster20:10

zedasnotmyname: thanks, and then that's doing a search of the tree and looking for a specific number of config files that comes from.....?23:45
notmynamezedas: unless the number is given it finds (and therefore launches) an instance for every conf file. so 4 conf files == 4 servers launched. the number can get passed in by swift-init (-c or --config-num)23:49
