15:34 championofcyrodi switched over to filter scheduler for my instances, bounced the service and saw in the log that it's using filter scheduler.
15:34 championofcyrodi however, I still cannot launch a host...
15:34 championofcyrodi http://paste.openstack.org/show/191619/
15:34 championofcyrodi (launch an instance*, not 'host')
15:37 championofcyrodi The warning about disk space being more than expected may be an issue.  I am using ceph for all the storage (compute,cinder and glance) and all hosts show the same disk space available.
15:39 dkusidlo joined #fuel
15:41 championofcyrodi i have 4 compute nodes, and retry filter only seems to be returning 2 of the 4...
15:41 championofcyrodi double checking compute service statuses.
15:41 KenV joined #fuel
15:42 corepb joined #fuel
15:43 kaliya championofcyrodi: flavor?
15:44 championofcyrodi m1.small
15:46 championofcyrodi kaliya: here is my cleaned up version of nova.conf: http://paste.openstack.org/show/191628/
15:46 mattgriffin joined #fuel
15:46 championofcyrodi by clean i mean i removed commented out options and blank lines for you.
15:47 kaliya so small, means 20G disk?
15:47 championofcyrodi yea
15:47 kaliya I still see compute_scheduler_driver=nova.scheduler.simple.SimpleScheduler
15:47 zerda joined #fuel
15:48 championofcyrodi wth??...
15:48 championofcyrodi sorry, stand by...
15:48 championofcyrodi oh shoot..
15:48 championofcyrodi i'm on one of the compute nodes not running the scheduler service...
15:49 championofcyrodi well at least now you can see the diff...
15:49 championofcyrodi http://paste.openstack.org/compare/191628/191630/
15:50 championofcyrodi node-46 is actually running the scheduler service (it is one of the HA controllers)
15:50 championofcyrodi 47 is a compute node and has the original config from the fuel deployer when simplescheduler was selected.
15:51 kaliya I think you must specify a scheduler_default_filters
15:51 championofcyrodi http://paste.openstack.org/show/191630/
15:52 championofcyrodi that is the copy on all my controllers
15:52 kaliya ah it is
15:52 kaliya paste `nova hypervisor-stats`
15:55 championofcyrodi ok...
15:55 championofcyrodi just made this.... but getting 'nova hypervisor-stats' now...
15:55 championofcyrodi http://paste.openstack.org/show/191633/
15:55 championofcyrodi http://paste.openstack.org/show/191634/ (nova hypervisor-stats output)
15:57 corepb joined #fuel
15:58 championofcyrodi storage used on the horizon UI is a little wonky because all storage is ceph (compute, volumes, images)
15:58 championofcyrodi so i think it's just adding up the total of instance attached volumes.
16:02 championofcyrodi not sure why node-52 fails from the retry filter at the start.  nothing is running on it
16:03 kaliya check the /var/log/nova/nova-scheduler.log to find if it's a disk matter, if it fails provisioning the disk
16:06 championofcyrodi on node-52?
16:07 championofcyrodi duh, of course not... that log/service is not on the compute node..
16:07 championofcyrodi checking node-46 (primary controller)
16:07 kaliya yes on controllers
16:11 championofcyrodi no i don't see anything like that.
16:11 kaliya errors in this log?
16:12 mescanef_ joined #fuel
16:14 championofcyrodi no errors in the last 12 hours in scheduler.log on and controllers...
16:14 championofcyrodi what is interesting, is node-46 shows 4 hosts returned from the retryfilter...
16:15 Samos123 joined #fuel
16:15 vkramskikh joined #fuel
16:15 kaliya what's the provisioning error exactly?

16:16 aglarendil joined #fuel
16:16 championofcyrodi 3 hosts returned from retry filter on node-50
16:17 championofcyrodi 2 hosts returned from retry filter on node-54
16:17 championofcyrodi shouldnt they all return the same number of hosts? if applying the same filter?
16:19 championofcyrodi i'm sure that if i try again a few more times, it 'might' eventually return a valid host and deploy the instance.  but i'm trying to make it perform better so i can deploy virtual clusters of say, 3-5 VMs at once where i can't have 1 or 2 fail while 3 deploy.
16:19 kdavyd joined #fuel
16:22 xarses joined #fuel
16:28 championofcyrodi kaliya: maybe the scheduler_host_subset_size=30 is an issue? since I only have 4 hosts?
16:28 kaliya mh no
16:28 emagana joined #fuel
16:28 kaliya did you enable ceph replicas?
16:29 championofcyrodi or group affinity
16:29 championofcyrodi yes
16:30 championofcyrodi just checked osds... all up and in, 0 obs degraded, volumes,compute and images pools have all size set to 3
16:31 championofcyrodi noted here (http://paste.openstack.org/show/191642/)

16:48 thumpba joined #fuel
16:50 championofcyrodi what if i just use the AllHostsFilter, Ram and CPU...(just those 3)
16:50 championofcyrodi that would likely enforce minimum instance requirements, and all hosts would just return all hosts w/o really filtering?
16:51 championofcyrodi since everything is ceph backed on Intel using x86_64 arch...
16:51 championofcyrodi there arent really any unique hosts
16:53 championofcyrodi i'm going to try stopping 2 schedulers, and just deploying with only 1.
16:54 thumpba_ joined #fuel
16:57 championofcyrodi kaliya: fyi... although the flavor has a limit of 20 GB, i am booting from an image, and creating a volume, where the image is 2GB and so is the volume.
16:59 kaliya championofcyrodi: there should not be such issues, should work. If instances provisioning is not working, you will have for sure an error somewhere, check nova-all.log
17:01 championofcyrodi oh good grief...
17:01 championofcyrodi <179>Mar 11 16:58:49 node-46 nova-conductor Error from last host: node-52.ccri.com (node node-52.ccri.com): [u'Traceback (most recent call last):\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 2014, in do_build_and_run_instance\n    filter_properties)\n', u'  File "/usr/lib/python2.6/site-packages/nova/compute/manager.py", line 2149, in _build_and_run_instance\n    instance_uuid=instance.uuid
17:01 championofcyrodi i forgot the image has video memory set higher to support qxl and higher resolutions on virtual desktops...
17:02 championofcyrodi apparently the error is 'nova.scheduler.utils' namespace, in the conductor.log
17:03 championofcyrodi seems like that error would be better fitted to output to the scheduler log... but i'm sure someone, somewhere has a reason for it being in the conductor service
17:04 championofcyrodi well, at the end of the day, this was the fix: "If instances provisioning is not working, you will have for sure an error somewhere, check nova-all.log" -kaliya
17:04 * championofcyrodi feels like such an amateur.
17:11 kaliya don't worry championofcyrodi we all are :)
17:12 championofcyrodi and there it is... spawned and running.
17:15 BobBall joined #fuel
17:18 BobBall Any way to re-run the setup wizard?  I had to reboot during the setup wizard (I used a terminal to verify the networking with ping and ctrl+c was being filtered out by something) and I suspect that it didn't save everything properly because nothing is listening on port 8000
17:30 e0ne joined #fuel
17:31 kaliya BobBall: just Create new environment
17:32 BobBall I mean the terminal setup for the network settings etc - I can't create a new environment as fuel-web isn't running and listening on port 8000
17:33 BobBall I can completely reinstall but I'd rather not do that as it was painful to get this far (for reasons specific to my infrastructure)
17:34 kaliya yes, go the the CLI and type `fuelmenu`
17:34 BobBall ah - perfect.
17:36 BobBall What should run fuel-web?  Just so I can track down why it's not running in case that doesn't work?
17:40 kaliya BobBall: mh?
17:44 BobBall OK - so I'm getting the same error when trying to setup with fuelweb that I was getting before that prompted me to use the console to check settings... I've got eth0 DHCP with external access and want eth1 providing the PXE server.  I've confirmed that eth0 gets a DHCP address just fine (and check on network setup page says the same) - but when trying to quit setup saving the changes it says it can't find a DHCP server on eth0
17:48 BobBall Is that configuration something which should work?
17:51 kaliya BobBall: yes should. But is eth0 DHCP in your case?
17:52 BobBall eth0 is externally-supply DHCP for lab+internet access
17:52 BobBall eth1 is Fuel-supplied DHCP for pxeboot
17:52 BobBall + management
17:52 BobBall seems that for some reason fuelmenu is clearing the default route when setting up eth0+eth1
17:53 BobBall dhclient is providing one for eth0 but when I apply changes through fuelmenu the default route disappears
17:53 BobBall if I ifdown eth0; ifdown eth1; ifup eth0; ifup eth1 I get the default route back
17:57 BobBall So I think the networking is fixed manually but fuel-web is still not running
17:58 claflico joined #fuel
17:58 kaliya BobBall: 6.0?
17:58 BobBall actually 6.1 ... :)
17:59 BobBall What should be running fuel-web?  you said mh, but what is that? :)
18:01 BobBall You're right, I'll start again with 6.0, but I would like to try and understand this too
18:01 kaliya the fact is that it might happen that the nightly build you pulled is somehow bugged
18:02 Longgeek joined #fuel
18:02 BobBall Very possible.
18:05 kaliya sorry BobBall I'm leaving the chat. Can you retry with a 6.0? In case write in here again. There will be colleagues and other users.
18:05 emagana joined #fuel
18:05 BobBall no probs - thanks for your help
