09:26 Kdecherf hm
09:27 Kdecherf when fuel-ha-utils/policy/set_rabbitmq_policy is executed?
09:28 Kdecherf (or how can i call it during deployment?)
09:37 ekosareva_ joined #fuel
10:08 aglarendil Kdecherf: it is executed in the late part of script itself when 'master' instance is started
10:09 aglarendil why do you need to call it during deployment?
10:09 aglarendil I mean, it is embedded into OCF script and is not intended to be called by itself
10:09 aglarendil DevStok: when you say 'restore', what do you actually mean?
10:10 aglarendil Kdecherf: regarding memcached. is it available for you by simple telnet?
10:14 DevStok @aglarendil hey , we have kilo in ha mode
10:14 DevStok today mysql cant sync with each other
10:14 Kdecherf aglarendil: well, i found what ocf stand for and understood my issue
10:14 DevStok so in node-1 i've got grastate ok but no number in index row
10:15 Kdecherf aglarendil: my cluster does not deploy rabbitmq HA because of the bug fixed here: https://github.com/openstack/fuel-library/commit/cf0e2eb6892ee6cf7b3198a1c50894d51542ada1
10:15 DevStok in node-3 grastate there is no numbers
10:15 aglarendil @DevStok what does mysql log in /var/log/remote/node-*/mysql*.log say
10:15 Kdecherf aglarendil: i will check that memcache stuff after lunch
10:16 DevStok http://paste.openstack.org/show/539683/
10:16 eric_lopez joined #fuel
10:19 aglarendil @DevStok there should also be a special log for OCF HA mysql script
10:19 aglarendil may be it stops mysql for some reason

15:04 aglarendil DevStok: I guess you have some issues with access rights
15:04 aglarendil try to chown /var/lib/mysql to mysql user
15:05 DevStok done
15:06 aglarendil DevStok: I guess it could be somehow related to our mysql bin logs. I recall mwhahaha was doing fixing something in them
15:06 DevStok thx
15:06 DevStok it's strange
15:06 DevStok crashed form yesterday night
15:18 Sketch hmm, when deploying, does fuel wait to reboot nodes until they are all done installing?
15:18 Sketch i have one node on 100mb and 2 on gigabit, but they all take the same amount of time to install
15:20 Sketch i was expecting the one on 100mb to be slower.  (note to self: order more rj45 sfps)
15:20 Sketch i assume it does the install over the admin interface, anyway

18:15 cr0wrx joined #fuel
18:16 cr0wrx Hello everyone. Anyone run into issues with fuel 9.0 - post installation scripts (technically MOS 9.0). Getting err code 127 during kickstart when trying to run /tmp/ks-script-*, the script isn't in /tmp so that's likely the problem
18:16 DavidRama joined #fuel
18:18 mmalchuk cr0wrx: this is well known problem, there is a bug
18:19 cr0wrx is there a bug listed or workaround for it yet?
18:19 mmalchuk https://bugs.launchpad.net/fuel/+bug/1605151
18:21 zephcom joined #fuel
18:22 mmalchuk maybe this is not exactly as yours fail, but related i think
18:22 mwhahaha cr0wrx: how were you installing from iso?
18:23 Sketch that sounds like the problem i had when i tried to pxeboot 8.0
18:23 mmalchuk yes, this is about PXE install
18:25 cr0wrx hrm it may be related but not sure
18:26 cr0wrx This is not PXE install, but virtual disk (dell idrac)
18:26 cr0wrx I don't see that cannot stat error message for ks.cfg
18:26 cr0wrx Actually, the ks-script file does seem to exist in /mnt/sysimage/tmp/
18:28 cr0wrx program log seems to hang at "running /bin/sh /tmp/ks-script-Lu5oNV". I see /mnt/sysimage/tmp/ks-script-Lu5oNV exists, however, and the error code 127 is in storage log, running kickstart script at line 1
18:28 mmalchuk cr0wrx: yea, wrong bug, can't find the similar to your problem, but I remember I see it
18:30 cr0wrx I'm not super familiar with kickstart process but it seems a lot of k-scripts are in /tmp, but not this one. It's in /mnt/sysimage/tmp instead
18:32 mwhahaha probably this bug? https://bugs.launchpad.net/fuel/+bug/1602229
18:32 mwhahaha that was via an HP but similar installation method
18:33 mwhahaha seems to be an issue with the virtual media install
18:34 cr0wrx hrm maybe
18:34 mmalchuk cr0wrx: coult you please create new bug
18:34 mmalchuk and please attach screenshot iа possible
18:35 cr0wrx Is there a way to have it re-run post-install part after reboot? I see comment #7 says workaround is to reboot and continue installation
18:35 cr0wrx not sure how that works, if I reboot from virtual drive again it wants to start all over, if I just reboot it starts up but doesn't seem to continue anything, centos installed but a lot of fuel specific things missing
18:37 mmalchuk cr0wrx: this is not the same issue as yours, so reboot couldn't help i think
18:38 mmalchuk cr0wrx: please create new bug, provide as much as possible details in the description and attach the screenshots if any
18:38 cr0wrx looking at his screenshot you may be right. I see "Pane is dead" on screenshot, I hit that when my virtual drive / internet connection hit some issues
18:38 mmalchuk https://bugs.launchpad.net/fuel/+filebug
18:38 cr0wrx but re-install and got past that
18:38 cr0wrx sure, I'll create a new issue
18:38 mmalchuk great, thanks
18:56 Sketch mwhahaha: so i got the rest of my controller hw up and running, and did a clean install again, 3 controllers + 3 compute nodes.  fuel's HA health tests still fail, say they can't find any online database.  they're obviously wrong since horizon is up and running and can configure things...
18:57 mwhahaha logs?
19:04 Sketch it actually looks like ssh is failing... https://rednsx.org/tmp/log/cluster_2_ha.log
19:04 Sketch not sure it's actually a problem, since mysql is actually running on all the hosts
19:05 mwhahaha did you change the ssh keys or anything?
19:05 Sketch i can ssh into all the hosts from fuel (with key) too
19:05 Sketch nope
19:05 Sketch though i did redeploy the nodes, with the same names this morning
19:05 Sketch (i reset the environment)
19:06 mwhahaha it looks like the ssh connection was fine, whatever it ran failed
19:06 mwhahaha not sure
19:06 Sketch so maybe fuel changed the key and didn't delete the old ones somewhere..
19:06 Sketch yeah, could be

19:46 Sketch mwhahaha: so, we figured out how to get to the floating net interface working.  not really sure why this was required: https://rednsx.org/tmp/log/fix.txt
19:47 Sketch only thing i can figure is maybe fuel doesn't expect the public interface to be on a vlan (even though i configured it as one in the webui..)
19:47 Sketch but it seems like it's not added in ovs for some reason
19:47 mwhahaha that looks like a bug in fuel
19:47 mwhahaha because we manage those mappings in the l23network module
19:47 mwhahaha you should report a bug and add that snippet
19:51 veena joined #fuel
19:51 mwhahaha Sketch: can you provide the output of 'hiera network_scheme' and 'hiera neutron_config' as well
19:52 mwhahaha https://github.com/openstack/fuel-library/blob/master/deployment/puppet/openstack_tasks/manifests/openstack_network/plugins/ml2.pp#L62-L66 is where the bridge mappings get generated from those
19:52 Sketch hrm https://bugs.launchpad.net/fuel/+bug/1562755
