not that sure, but i could just stop logging on one web server for few minutes to verify it

I asked some questions regarding his project. Very defensive. Says you spoke to him, then didn’t reply, then you ruaok called him a ‘dumbass’ on IRC (unaware he is on here).
Asking someone to sign-up and what they are doing with our database, I believe is fair. We don’t ask all users to give $$. I do ask for confirmation of non-profit status or general details on the goals in order to determine fairness. -sigh-
ruaok
sigh.
well, clearly this isn't going anywhere. putting him in the penality box is only going to make it worse.
I think a polite email asking him to stop using musicbrainz and not bother with the link might be the best way forward.
chrisskye
Also, if you are building a database of popular music...and somewhere link to us...is it not fair to ask how that metadata was put together? I mean, just for interest even...
Yes...but he included a veiled threat to blog about us in a negative way...

About db server, using SSD will speed up things by, in the very worst case, a factor x3 (and prolly up to x20 with recent SSD/kernel/postgresql) (based on old HDD/SSD comparison at http://it-blog.5amsolutions.com/2010/08/perform...)
And also our local network should be much faster
ruaok
so start with 1 DB server one failover?
zas
Yes, one master, one slave
Those machines have the biggest spec, they need fast CPU/fast and big RAM/fast and big SSD/fast network card
About search servers, we can just add another one
ruaok
I wonder if we can start with two.
if we have SOLR in place.
because when not freaking out, they are at 20% CPU.
doubling would be 40%.
zas
Still they are slow
ruaok
I think SSDs might help
zas
I think software is just damn inefficient
ruaok
yes.
which is why I want to start small, observe and then grow.
I mean with vrack, adding a new machine should be near trivial.
zas
Ok. so 2, with better specs than current ones, and a third one if not sufficient
ruaok
perfect.
zas
I think redis machines could be used for stats too
speaking of which, time to head there and see if we have power and see if the net works, if we do have power.

reosarevok
Pretty!
Not MeB though? :p
ruaok
Also not done yet, reosarevok. :-)
reosarevok
Do you have THE POWER?
KodeStar
ruaok / zas, I still think you should consider using proxmox, it will allow you to officially utilise the servers, especially for something like the redis servers, as you can give cpu priority and assign memory
reosarevok
(meh, it's hard to pronounce stuff properly METAL-y when writing)
KodeStar
-officiall + efficiently
also with servers with a lot of memory you might not notice that big a difference in speed between ssd and hdd if most of you operations are read and the databse fits into ram
and if something crashes in 1 container it's not going to bring the whole server down
another benefit is the public ip of the container isn't the public ip of the actual server
so you could disable ssh completely to the public ip for example and only connect to it via the actual server then "pct enter 100" for example to enter the container
ruaok
no power, reosarevok.
reosarevok
Aww
ruaok
only some more clues for the next puzzle.
we contracted power a week ago.
over a week and it was supposed to take a week.
reosarevok
A Spanish week? :p
ruaok
now, if this is anything like with the water, I need to go to the meter and turn it on. they didn't do that.
see, I don't know. :)
there is a door where the power meters might be, but none of the keys that were supposed to open everything open everything.
so, now we need to go back to the rental agency and figure out how to get access to that. or call the power company and figure out if they actually did turn shit on.
all I know is that after 2 hours, my fukkits are gone for the day.
I really want to try the net connection, but I have nothing that can produce 12V for any length of time.
zas: yeah, whenever I want to ask, no one is around.
zas
You can easily get 12V from a bunch of 1.5V batteries

I'd need D cells for that to work well.
and I dont really care to spend that money on this

KodeStar: proxmox looks very interesting
MajorLurker has quit
KodeStar
zas I use it on my servers (though I haven't attempted a cluster) and it makes things so much easier, if a particular container is using too many resources you can either restrict the resources the container is allowed or move it to another node that has more spare capacity
zas
KodeStar: do you use proxmox HA cluster ? it is said it requires 3 physical nodes at least
KodeStar
zas, no, I only have 2 servers currently
zas
If we go for proxmox, i will set it up for HA cluster
KodeStar
so I run them as stand alone
it means I cant transfer between nodes without some down time, but that's ok for my needs
zas
ruaok: the more i read about proxmox the more i think it would be absolutely great for us, as a far better catchall VM
ruaok
good because that xen setup seems to fragile.
zas
with 3 physical nodes we'll get a very solid solution, and we can provide sandboxes to our devs (as VMs)
our xen machine is a very weak point
KodeStar
you can also use kvm if you want to guarantee resources (similar to xen) or you can use lxc containers which are much more efficient
tbh i'd only ever use kvm vms if I needed to, like for a windows vm
zas
lxc containers would be perfect for mbs dev envs
KodeStar
yeah
zas
ruaok: i wonder about network links, ideally they have to be redundant, with no single point of failure
KodeStar: i mean between private network machines, ideally we should have 2 network cards, with 2 switchs to interconnect them, to prevent any serious failure of the whole system if a switch fails
KodeStar
hmm, you might struggle to get that from any of the budget providers
Well, i mean the most stable and performant is our system, the more we can provide services to big players, so...
!m LordSputnik
BrainzBot
You're doing good work, LordSputnik!
KodeStar
even without a budget it might be difficult, if you want 2 network cards between private network machines, must providers either have a single card for public network or 2 cards, 1 for public network and 1 for private
and by budget providers, one you go away from the big 3, you end up paying 2-3x he amount for worse specs
zas
KodeStar: atm we have 3 (public + 2 privates) or 2 (private) network cards on most machines

lots of typos though, but typing with 1 hand and trying to calm a crying 6 month old with the other, lol
zas
ahah, i know that ;)
KodeStar
zas, those are your own machines though, you can put what you like in them
ovh might allow some customisation though
you would have to ask them

vRack means we don't have any switch etc.. so the single point of failure is the network card (and those are quite reliable), so till we have redundant machines/services not much an issue

Our search servers are very stable, only 7 crashes within 3 hours...
KodeStar
sweet, you should talk to google about that, sure they would love to see howyou made it that stable
I mean, personally i'd try shooting for a crash every 20 minutes, but that's just me
