07:56 julien_ZTE Hi, I use Fuel to deploy 3 control nodes. There are huge message in nova-api.log in one node which vip__management exists. About 2MB per second will be written into the file. The harddisk will soon run out of resources. There are large number of green socket error in the file nova-api.log
07:57 julien_ZTE Maybe 3 or 4 hours, the file get 40GB size.
07:57 julien_ZTE There are 10K link in this node, and 90% are relevant with 11211 port

15:31 Verilium Whoa, nice changes on the UI in 7.0.  Slick.
15:39 Verilium The way everything has been split off into a settings tab is great.

15:42 kaliya Yep Verilium
15:49 RageLtMan joined #fuel
15:50 RageLtMan is there a rational way to bring down a openstack cluster with a single master node? Deployed with fuel 7 and realized after rebooting the master that galera wants to sync and cant...
15:51 ktychkova joined #fuel
15:52 kaliya RageLtMan, the master or the controller?
15:55 vsedelnik joined #fuel
15:55 RageLtMan Controller, pardon, my terms are still a bit hazy on this
15:55 RageLtMan The node running horizon and such
15:56 xarses joined #fuel
15:58 angdraug joined #fuel
15:58 nihilifer RageLtMan: generally fuel above 6 version is designed to deploy at least 3 controllers, and we are very rarely checking cases with single controller deployments
15:59 RageLtMan Documentation says its supported...
15:59 RageLtMan What happens when the datacenter loses power or something, do you just lose the stack?
15:59 RageLtMan Seems like a maintenance nightmare
16:00 kaliya RageLtMan, however, it's possible that galera tries to use lots of system resources after a reboot (especially if the controller is virtualized). 1 controller but it still has HA
16:00 kaliya RageLtMan, in production, you must run typically 3 controllers
16:00 RageLtMan Controller IS virtualized actually
16:00 RageLtMan Thats a pretty serious resource hit for a 5 compute node cluster, the controllers arent "light"
16:01 RageLtMan We also run ZFS for storage so we kind of need to virtualize the controller/storage nodes since there's no native driver
16:01 kaliya RageLtMan, what is it, 6.1 ?
16:01 RageLtMan 7.0 built on 20150831
16:01 kaliya Ahhh, try the RC2
16:01 RageLtMan Where would i find it? i got thsi from the nightly page
16:01 RageLtMan this*
16:01 kaliya 7.0 might still have serious bugs
16:02 e0ne joined #fuel
16:02 kaliya RageLtMan, https://ci.fuel-infra.org/view/ISO/
16:03 RageLtMan The plan here is to migrate our current cloudstack VMs because that stack appears dead as a doornail - GRE isolation on XenServer is just plain broken and not being fixed, so we'd like to do kilo for the image conversion facet
16:05 kaliya RageLtMan, 7.0 is going to be released in 10 days, so if you plan to run it in prod, I suggest you to wait for GA
16:05 RageLtMan Also, if 3 nodes are required, why do docs say that that is only for HA? I dont care much about HA here - this is a small in-house setup for our datacenter, but not being able to recover from a full-down scenario is a complete nonstarter for any of the clients we work with
16:05 RageLtMan We will be rebuilding once its out
16:05 RageLtMan meantime we're trying to figure out if this is a viable approach for us and our clients
16:05 kaliya RageLtMan, 3 nodes are best option. We do support 1 controller HA with the idea that later you will add other 2
16:05 RageLtMan (mirantis is already aware of at least one of the large opportunities around this)
16:05 RageLtMan Can we disable HA altogether though?
16:06 RageLtMan Prod clients will run HA, but even they wont do it if loss of all controllers means loss of cluster - thats just bad planning
16:06 kaliya Yes, but it requires some CLI hacks, you should find it in docs
16:06 RageLtMan Thank you :).
16:06 RageLtMan Will start digging
16:06 kaliya NP RageLtMan ;)
16:06 RageLtMan any place i should start looking that you know of?
16:07 RageLtMan Far as actual HA setups go, whats the procedure if all nodes go down? Major outage, security issue, whatever it is that kills all things
16:11 kaliya Yes, you should work with the CLI, download the YAML file
16:11 kaliya evg, ^^
16:11 RageLtMan evg?
16:12 RageLtMan ah. handle.
16:13 RageLtMan By the way, are most of the mirantis dev staff in the US or Russia? Kinda surprised its not just all Cyrillic text in here (i was born in Moscow and dont often see chans populated like this outside certain infosec ones)
16:15 kaliya RageLtMan, Mirantis is an international company. I am italian
16:16 kaliya RageLtMan, ну, я немного русский язык говорю )
16:16 RageLtMan I only really interact with some of the sales folks on the finserv and healthcare arenas in the US..
16:20 RageLtMan One of the oddities of the language is that we lack any formal sentence structure, so aside from the minor grammatical omission, it comes out a bit more naturally as я немного говорю по русский, or likely я немного понимаю русский язык (being that one understands it as opposed to speaking)
