I think this is a good idea. 3 days may be a good idea, as well.

I think I would be more useful trying to bring the user's perspective
more so than a developer's. So on that, I would like to propose a
discussion on merging some of the disparate lists, channels, sites, etc.
to help simplify life for new users looking for help from or to wanting
to join the HA community.

I also understand that Fabio will buy the first round of drinks. >:)

Could you please let me know by end of Nov if you are interested or not?

I have heard only from few people so far.

Well, no. ;-)

But I'll still be there,
and a few other Linbit'ers as well.

Fabio, let us know what we could do to help make it happen.

I appreciate the offer.

Assuming we achieve quorum to do the event, I´d say that I´ll take of
the meeting rooms/hotel logistics and one "lunch and learn" pizza event.
It would be nice if others could organize a dinner event.

Cheers
Fabio

Folks, Fabio,

thanks for organizing this and getting the ball rolling. And again sorry
for being late to said game; I was busy elsewhere.

However, it seems that the idea for such a HA Summit in Brno/Feb 2015
hasn't exactly fallen on fertile grounds, even with the suggested
user/client day. (Or if there was a lot of feedback, it wasn't
public.)

I wonder why that is, and if/how we can make this more attractive?

Frankly, as might have been obvious ;-), for me the venue is an issue.
It's not easy to reach, and I'm theoretically fairly close in Germany
already.

I wonder if we could increase participation with a virtual meeting (on
either those dates or another), similar to what the Ceph Developer
Summit does?

Those appear really productive and make it possible for a wide range of
interested parties from all over the world to attend, regardless of
travel times, or even just attend select sessions (that would otherwise
make it hard to justify travel expenses & time off).


Alternatively, would a relocation to a more connected venue help, such
as Vienna xor Prague?


I'd love to get some more feedback from the community.

As Fabio put it, yes, I *can* suck it up and go to Brno if that's where
everyone goes to play ;-), but I'd also prefer to have a broader
participation.

Lars

I agree. some feedback would be useful.

dates and location were chosen to piggy-back with devconf.cz and allow
people to travel for more than just HA Summit.

I´d prefer, at least for this round, to keep dates/location and explore
the option to allow people to join remotely. Afterall there are tons of
tools between google hangouts and others that would allow that.

I suspect a lot of it is that, given people's busy schedules, February
seems far away. Also, I wonder how much discussion has happened outside
of these lists. Is it really that there hasn't been much feedback?

Fabio started this ball rolling, so I would be interested to hear what
he's heard.

Requested feedback given;

Virtual meetings are never as good, and I really don't like this idea.
In my experience, just as much productive decision making happens in the
unofficial after-hours activities as during formal(ish)
meetings/presentations.

I think it is very important that the meeting remain in-person if at all
possible.

Personally, I don't care where we meet, but I do believe Fabio already
ruled out a relocation.

Yeah, well, devconf.cz is not such an interesting event for those who do
not wear the fedora ;-)

That is, in my experience, the absolute worst. It creates second class
participants and is a PITA for everyone.

I know that an in-person meeting is useful, but we have a large team in
Beijing, the US, Tasmania (OK, one crazy guy), various countries in
Europe etc.

Lars

I would be interested in the "user" conference rather then the "dev" one,
so the 1st day of the 3 days option mentioned by Fabio.

I will stay tuned!

Its not necessarily the conference of choice even for people that do.
I just do what I'm told :)

I personally disagree. In my experience, one either does a face-to-face
meeting, or a virtual one that puts everyone on the same footing.
Mixing both works really badly unless the team already knows each
other.

Yeah, but you're already bringing him for your personal conference.
That's a bit different. ;-)

OK, let's switch tracks a bit. What *topics* do we actually have? Can we
fill two days? Where would we want to collect them?

Personally I'm interested in talking about scaling - with pacemaker-remoted and/or a new messaging/membership layer.

Other design-y topics:
- SBD
- degraded mode
- improved notifications
- containerisation of services (cgroups, docker, virt)
- resource-agents (upstream releases, handling of pull requests, testing)

User-facing topics could include recent features (ie. pacemaker-remoted, crm_resource --restart) and common deployment scenarios (eg. NFS) that people get wrong.

If we're going to talk about scaling, we should throw in our new docker support
in the same discussion. Docker lends itself well to the "pet vs cattle" analogy.
I see management of docker with pacemaker making quite a bit of sense now that we
have the ability to scale into the "cattle" territory.

Yep, We definitely need to talk about the resource-agents.

Adding to the list, it would be a good idea to talk about Deployment
integration testing, what's going on with the phd project and why it's
important regardless if you're interested in what the project functionally
does.

This my be something my company can bring to the table. We just hired a
dev whose principle goal is to develop and alert system for HA. We're
modelling it heavily on the fence/resource agent model with a "scan
core" and "scan agents". It's sort of like existing tools, but designed
specifically for HA clusters and heavily focused on not interfering with
the host more than at all necessary. By Feb., it should be mostly done.

We're doing this for our own needs, but it might be a framework worth
talking about, if nothing else to see if others consider it a fit. Of
course, it will be entirely open source. *If* there is interest, I could
put together a(n informal) talk on it with a demo.

I´d say either a google doc or any random etherpad/wiki instance will do
just fine.

As for the topics:
- corosync qdevice and plugins (network, disk, integration with sdb?,
others?)
- corosync RRP / libknet integration/replacement
- fence autodetection/autoconfiguration

For the user facing topics (that is if there are enough participants and
I only got 1 user confirmation so far):

- demos, cluster 101, tutorials
- get feedback
- get feedback
- get more feedback

Ok, I do have a topic I want to add;

Merging the dozen different mailing lists, IRC channels and other
support forums. This thread is a good example of the thinness that the
community is spread over.

A 'dev', 'user', 'announce' list should be enough for all HA. Likewise,
one IRC channel should be enough, too.

The trick will be discussing this without bikeshedding. :)

Just my 2c.

- It would be interesting to get some bird-view information
on what C APIs corosync and pacemaker currently provide to application
developers (one immediate use-case is in-app monitoring of the cluster
events).

- One more (more developer-bounded) topic could be a "resource degraded
state" support. From the user perspective it would be nice to have. One
immediate example is iscsi connection to several portals. When some
portals are not accessible, connection still may work, but in the
"degraded" state.

Best,
Vladislav

What, you want to bring the guy who's boldly maintaining the outpost on
the southern frontier? ;)

*cough*

Barring a miracle or a sudden huge advance in matter transporter
technology I'm rather unlikely to make it, I'm afraid. But I'll add my
voice to what Lars said in another email - go all physical (with good
minutes/notes/etherpads for others to review - which I assume is what's
going to happen this time), or all virtual. Mixing the two is
exceedingly difficult to do well, IMO.

Regards,

Tim
