07:21 < ewoud> jclift: that's log origin/master..HEAD or something
similar I assume
07:21 < quaid> ewoud: I was thinking about that, figured if we're doing
e.g. sql dumps, those are automatable - the challenge would be perhaps
more in mirroring databases if we had many of them
07:21 < jclift> ewoud: Yep
07:21 < quaid> I'm forgetting, did we setup the git repo for Infra?
07:21 < ewoud> dcaro: can I see the work somewhere?
07:22 < quaid> how does it come in to play here? does foreman/puppet

should mention the review requests

this Gerrit crap?
07:24 < jclift> :)
07:25 < ewoud> jclift: no, they're meant as a read-only method

07:26 < jclift> quaid: No.
07:27 < quaid> jclift: ok, didn't sound like it but ...
07:27 < jclift> jclift: I think I'm just having conceptual issues with
Gerrit. :)
07:27 < ewoud> jclift: that looks very weird; maybe HEAD isn't the
branch you want to push?
07:27 < jclift> After this patch, I'm never touching it again.
07:27 < jclift> ewoud: master HEAD is where I have the patches.
07:28 < jclift> I first tried with a branch "typo_fixes_v2", but
wasn't
sure how to do stuff with branches with Gerrit.
07:28 < jclift> So, I just did it in master instead.
07:28 < ewoud> jclift: if you do branches I think git-review makes your
life a lot easier

07:29 < jclift> I have no intention of ever doing anything with the

07:29 < jclift> (unless it moves to GitHub or something sane)
07:29 < jclift> So, not really going to invest time into learning new
tools just for this purpose.
07:29 < jclift> Hmmm.
07:29 -!- lvernia [~lvernia(a)nat-pool-tlv-t1.redhat.com] has quit [Quit:

07:30 < jclift> I think I'll just "abandon" this change set, and
someone
else who knows Gerrit can fix the typos in things when they're bothered. :)
07:30 < ewoud> jclift: http://gerrit.ovirt.org/#/c/5541/ is the only
commit that shows up?
07:30 < jclift> ewoud: Yep
07:31 < ewoud> jclift: you could try to push to
refs/for/master/typo_fixes to make a branch
07:32 < ewoud> jclift: btw, I think I see what's the problem
07:32 < ewoud> all the commits have the exact same change id
07:32 < jclift> Yep
07:32 < ewoud> which means gerrit things it's the same change
07:32 < jclift> That ties them together doesn't it?
07:32 < quaid> btw, who is writing the master/slave hostgroups in to the
Etherpad?
07:32 < jclift> They're part of the same change.
07:32 < ewoud> jclift: no, a change ID means it's a unique trackable commit
07:33 < jclift> Hmmm. I don't have an "Abandon Change" button.
07:33 < jclift> How do I abandon/nuke/etc this change?
07:33 < ewoud> jclift: just give the other commits a new ID, push and it
should work
07:33 < ewoud> jclift: I'll assume the first commit is still valid
07:34 < ewoud> jclift: change IDs are a means of tracking multiple
versions of a single patch
07:34 < jclift> How do I tie multiple patches into one related "change" ?
07:34 < jclift> Or is that not possible?
07:34 < ewoud> jclift: I think you push to refs/for/master/<my_branch_name>

07:35 -!- eedri [~eedri(a)nat-pool-tlv-t1.redhat.com] has joined #ovirt
07:37 < quaid> ewoud: regarding the smart proxy, is that something we'd
want bundled on the same server with Puppet, or would that be a
stand-alone host, too?
07:38 < dneary> quaid, What agenda item are we on? I'm a little lost
07:38 < ewoud> quaid: We need to run puppet on the smartproxy because it
managed /etc/puppet/autosign.conf for example
07:38 < dneary> Ah - hosting plan
07:38 < dneary> Never mind me
07:39 < quaid> yep, and on the Etherpad

07:39 -!- shireesh [~shireesh(a)nat-pool-sin2-t.redhat.com] has joined #ovirt
07:39 < ewoud> also, we need to install puppet from the puppetlabs repo
because the server needs to be >= clients
07:40 < ewoud> and afaik F17 is puppet 2.7 where EPEL6 is 2.6
07:40 < eedri> ewoud, i think we have puppet master on rhel and it
managed fedora clients
07:41 < ewoud> eedri: I have no fedora clients, but pretty sure I heard
something about that

Fedora slaves)
07:44 < ewoud> jclift: any luck changing the IDs?
07:45 < eedri> ewoud, are you chatting on the pad? cause i don't see it
07:45 < eedri> ewoud, or just reviewing the items

typo_fixes_v3:refs/for/master/typo_fixes_v3
07:45 < jclift> Does that sound right?
07:46 < ewoud> jclift: I think it does
07:46 < jclift> The new commits, with changed id's, are in a new
"typo_fixes_v3" branch.
07:46 < jclift> k, lets see what happens.

network admin
07:50 < eedri> ewoud, ssh works.. but http/git doesn't
07:50 < eedri> ewoud, so i'm not sure it's a network issue
07:51 < jclift> ewoud: Is that good or bad? It's now 7 separate changes.
07:51 < jclift> Should I just leave it alone now, or just abandon it
something.
07:51 < jclift> I'm completely over putting any more effort into this. :)
07:52 < ewoud> jclift: yes, every commit becomes a change and I think
you're fine now and just wait for a review

07:54 < jclift> Every other project on the planet seems to manage it. ;)
07:54 * quaid looks
07:55 < dcaro> should we install ovirt to handle the vms?

07:57 < eedri> quaid, what's the best approaach
07:57 * quaid will work on the bot later today
07:57 < eedri> i think installing foreman + puppet master from stable

and update them, we can skip that part of this meeting
07:59 < quaid> eedri: Kevin said he's installing base OS today
07:59 < eedri> quaid, ok.
07:59 < eedri> quaid, assuming we don't have foreman server yet, we'll

own dogfood, but not sure how much overhead it is when we only have one
machine running VMs
08:00 < quaid> I think it's OK to push ahead in parallel as long as we
are including the manual installs in Foreman later
08:01 < eedri> quaid, we can later on add the relevant hostgroups to
manage already installed servers
08:01 < quaid> great

itself, and I think perhaps we'll find it worthwhile, but I think we're

08:18 < dcaro> quaid, I think that the benefits of having ovirt will
start to become relaly noticeable with the migration, as we are starting
to have more vms (also I think that using our own software should be a
must xd)
08:19 < quaid> I'm +1 with doing it, for sure

08:32 < quaid> ewoud: for Jenkins?
08:32 < quaid> aiui, we want Jenkins on it's own host, but why did I get

08:33 < ewoud> quaid: yes, I think eedri said something like that but
I'm wondering if we get sufficient performance from a VM
08:33 < ewoud> if a VM is sufficient we could go for ovirt
08:33 < quaid> I guess the need for nested qemu v. bare metal (iirc) is
more on the slave side?
08:34 < ewoud> yes

08:34 < ewoud> in the ideal situation the master is only a master and
doesn't run jobs afaik
08:35 < quaid> ewoud: btw & OT, I'm almost definitely coming to Brussels
on Friday night & spending most of Saturday at FOSDEM
08:35 < quaid> ok, no problems, master doesn't run jobs, but yeah, if it
can be a VM we can use that host more efficiently
08:35 < ewoud> quaid: cool
08:35 < eedri> quaid, ewoud i've also tried to think if jenkins really
needs it's own single bare metal server
08:35 < ewoud> quaid: I'm not sure what jenkins does under higher load
of many jobs
08:36 < eedri> quaid, ewoud but i can't know for sure if running it on a
vm will provide enough performance
08:36 < ewoud> quaid: I think foreman devs are planning something on
saturday evening, like dinner
08:36 < quaid> RobertM: did you have some insight about Jenkins on its
own bare metal v. VM?
08:36 < eedri> quaid, perhaps the bad experience we had from using an
amazon vm affects the decision
08:37 < quaid> ewoud: cool, I'm heading back to Paris sometime on
Saturday night, but it could be a late train ride
08:37 < eedri> quaid, ewoud i can say we're using vms to run
foreman,puppet,gerrit

08:38 <@RobertM> quaid, I can tell that the master uses a lot of IO so
what every you go with needs to strong IO.
08:39 < ewoud> eedri: that's what makes my experience harder to extrapolate
08:39 -!- Udayendu [~ukar(a)nat-pool-pnq-t.redhat.com] has joined #ovirt
08:39 < ewoud> RobertM: was the master running jobs as well?
08:39 < quaid> RobertM: I think we have that included, though I haven't
seen the actual specs from AlterWay, we included fast IO in the initial
requests
08:41 <@RobertM> I was running jobs at first but as the number of slaves
went up the number of jobs I could run on the master went down.

08:45 -!- lhornyak [~lhornyak(a)nat-pool-brq-t.redhat.com] has joined #ovirt
08:46 < quaid> so I'm unsure now, was the problem that you were also
running jobs on the master? or is it that ultimately Jenkins master will
collapse on a VM and needs bare metal with fast IO?

08:47 -!- mbetak [~mbetak(a)nat-pool-brq-t.redhat.com] has joined #ovirt
08:47 < eedri> RobertM, but if we assign an external io to the master,
fast enough.. it might be enough.
08:48 <@RobertM> quaid, Ever job requires you to copy to the slave then
copy back from the slave that is a lot of IO the more jobs you run the
higher that IO gets. Please that becomes a bottle neck for the entire
process. So do skimp on the master
08:48 <@RobertM> please=plus
08:49 <@RobertM> do=dont
08:49 < quaid> heh, that wsa a useful typo fix, thanks
08:49 <@RobertM> Also my keyboard is failing so it is really effecting
my ability to type.
08:50 < quaid> I'd say, we could probably start with Jenkins owning that
host, and watch the usage over time - if it ends up having spare CPU &
RAM, we could consider changing and watching

08:50 < eedri> quaid, sounds good
08:50 < eedri> quaid, if we'll see we're short on bare metal hosts
08:50 < eedri> quaid, it will be easy enough to install a new jenkins vm
on existing system

08:56 < quaid> +1
08:56 <@RobertM> CPU and Ram requirements are pretty minor. My system
has 16G or ram and 8 core and it was way overkill. I found the master
only used around 6G or ram and the CPU were never busy. Now IO on the
sata drive got nuts.
