rfreiremugsie, morning Graham!13:43
rfreireThat ktibi guy that showed up yesterday13:43
rfreirehow did that end?13:44
mugsieI didn;t see anything else :)13:46
mugsieyou must have fixed it for him \o/13:46
rfreiremugsie, haha yay!!!!13:46
*** McClymontS has joined #openstack-dns13:55

mugsiefrickler: for the new jobs - is there a reason we are adding py36 as voting in check, but not in the gate?14:18

*** rfreire has quit IRC14:28
fricklermugsie: when I developed this, bionic was not officially released yet, so not suitable for gate jobs. but you were so fast with merging this yesterday, I only got round to checking the journal collection did work as planned now. ;)14:32
*** rfreire has joined #openstack-dns14:33
fricklermugsie: I guess we can leave it as is for a week or so and watch things and then add the job to the gate, too14:33
mugsieah, makes sense :)14:33
mugsieI was just happy to see this done14:33
rfreiremugsie, looky; side question14:33
rfreiremugsie, do you do overcommit in your KVM hypervisors?14:33
mugsieIn some cases, yes14:34
* mugsie is currently learn how everything is laid out in here14:34
rfreiremugsie, in who do you rely for the memory overflow? ksm or swap?14:34
mugsieeh, that is a very valid question that I do not know :/14:34
mugsieI don't think we overcommit memory14:34
rfreiremugsie, I learnt that I was  doing all wrong14:35
rfreireMy custy relied in KSM14:35
rfreirebut ksm has several limitations14:35
rfreireincluding NUMA boundaries - it never cross a domain to merge a page14:35
rfreirethus hindering effectiveness14:35
rfreireksm does no miracles14:35
mugsieoh, I did not know KSM was based on NUMA boundries14:35
rfreireI learnt that the most effective way to do the overcommit is by providing copious amounts of wap14:35
rfreire*swap14:35
* mugsie files that nugget of information away for when I need it14:36
rfreireqemu-kvm keeps track of hot and cold pages (lru) making cold pages candidates to swap14:36
rfreireand smartly swaps them off14:36
rfreireso let a 1 TB RAM hypervisor14:36
rfreireit is no shame to have 200-300 GB of swap space for the hypervisor14:37
rfreirethe only restriction is that it should be FAST14:37
rfreireread, local SSD hdd or high-end storage LUNs or striped mid-end storage LUNs14:37
rfreirefyi14:37
rfreire:-)14:37
rfreireI have just _ABUSED_ my laptop here; I have put two SSDs in stripe mode14:38
rfreireDeployed around 60 GB worth of raw instance memory (in a 32 GB laptop)14:39
rfreireman14:39
rfreireit worked GOOD.14:39
mugsiewhat laptop do you have?!?14:39
rfreireW54114:39
rfreireLenovo14:39
rfreireThinkpad14:39
mugsieoh, they are monsters14:39
rfreireheck of a nice system sir14:39
rfreirethink I'll talk about it in the RDO booth14:40
* mugsie prefers a mad desktop and a lightwight laptop14:40
rfreireI'm on the road 3 times a week14:40
rfreireunfortunately, I need a beefy machine14:41
rfreirethat gave me serious back ache14:41
rfreirewhich was solved when I bought a stroller backpack14:41
rfreireBecause it is _HEAVY_14:41
mugsieYeah, that sounds like a good plan14:41
mugsiefrickler: the only issue I can see with the new logs is the /etc/bind/* files are getting the wrong MIME types, and being downloaded instead of displayed14:44
mugsiebut having the bind log is awesome14:45
fricklermugsie: yeah, we'd need to rename them all to .txt.gz, but I'm not sure it is worth the effort. might be good enough to have the files at all in the rare case one needs to dig deeper14:47
mugsiefrickler: for sure14:48
fricklermugsie: I'm more thinking on how to make that part dynamic when testing other backends14:48
mugsieyeah, that would be good - possibly something in the devstack plugin?14:48
*** McClymontS has quit IRC14:49
fricklermugsie: maybe I can add variables to the role and set those in the job definition, that might be the cleanest solution14:50
fricklermugsie: anyway, time to enjoy the afternoon traffic here, bbl14:50
mugsiefrickler: enjoy14:50
