As you can see, K5 is finally back. I don't have very much to add to the ongoing history chronicled in our dispatches from the front lines of Operation Enduring Downtime, but I did want to profusely thank some people, and describe the new hardware setup both current and near-future. Update [2001-12-16 1:9:35 by hurstdog]: You might be seeing a few Internal Servers Errors when you load a page. Maybe about 1 in 20 loads. We know about it, no need to email rusty. I'm digging into it now.
Update [2001-12-16 1:27:11 by hurstdog]: oddly, restarting apache fixed it. (knock on wood). You may go back to reading k5 sans error messages now :)


First, the thank yous

In the first days of the disaster, Jason Camp of VHosting worked tirelessly trying to get bubba to come back from the dead. To no avail, unfortunately, but both for that, and for all the great support he's given us for the past year-and-a-few-months, I am eternally in his debt.

Voxel.net stepped in with an offer of new hardware and redundant cluster hosting, so that future single-machine failures won't have this kind of effect. It was a scheme we've been wanting to pursue for a while, and they have a lot of experience with highly-available server clusters, so we jumped on that. They have worked tirelessly, and provided probably the best support I've ever seen anywhere in getting this new setup going. And it has not been an easy road.

Specifically, I have to thank Raj, Voxel's President, who went so far as to call me from Singapore, where he's on vacation, to let me know what the status of the project was. Andres, who wrestled with LVS last night until 6AM, finally getting it to work properly, and Jim, who put in similarly long hours and great effort overcoming what has surely been the most problem-ridden installation in history.

Anybody can do something and have it go perfectly right off. What really shows you what people are made of is how they act when everything goes wrong, and these guys are a class act.

Finally, I have to thank our still-anonymous no longer anonymous (!) friend, el_guapo, at Compaq, who also went to great lengths to rescue our data from bubba's arrays. I'd love to name in if he were to give me permission to do so. But until then, he remains our anonymous friend.

So what's going on now?

Right now, the site is running on a total of three machines. One lightweight box in front is running LVS, which is a Linux load-balancing system. It's splitting requests off to two dual P700s, one of which is running Apache and Scoop, and the other of which is running Apache, Scoop, and MySQL. Both are using the one database, and LVS is configured to favor the scoop-only machine for web connections, to compensate.

All this is because the database machine (formerly known as "hex" for those of you who keep up) is having kernel trouble. Very soon, it will come back online, and there will be a brief outage while we move the database back onto it's own box. Really, it'll be minutes. I promise. ;-)

The Future

Once the four-machine cluster is running smoothly, we will be swinging into action to build it up and ensure full redundancy. Promicro Systems, who built the two new Scoop machines we're running on now, is going to become a hardware sponsor, and hook us up with some more new machines, to fill in wherever the current system isn't fault-tolerant. We hope to end up with:

  • Two quad Xeon database servers, one live, one mirroring the live one, as a hot spare
  • Four Scoop servers, dual P3 class
  • Two LVS frontends, one hot-spare which will take over if something happens to the live one
This should bring us to a point where the cluster can expand as needed, and won't be so fragile with respect to hardware failure.

And yes, from now on, we're going to keep backups.

by rusty on Sat Dec 15, 2001 at 04:39:34 PM EST

Yes, there are time issues. As I mentioned, "unexpected problems" might crop up, and here they are.

The two running boxes are both two hours behind EST (where they should be), and are out of sync by 8 minutes or something. This out of syncness is causing some weird behavior with comment counts and marking "new" comments. We'll have it fixed up in a jiff. Or two jiffs, perhaps.

Two people who regularly access k5's box, rusty and inoshiro. When rusty leaves, k5 dies.

The obvious, and only reasonable, answer is that inoshiro is brainwashed by the canadian government to take down k5 when there's no other supervision due to the fact that k5 is anticanadian and bad. Ask legolas about k5's policy on canadians.

I'm curious, when I first saw the number of comments on that story I thought for sure that you were undergoing a DoS attack or something, then I loaded it up and saw that there was indeed 2000 (now its at about 3.5k) or so unique comments. The only thing that surprised me more is that they were all saying the same thing. Where did you manage to find a group of people who are so dimwitted as to think saying the same things over and over again ad infinitum makes a solid argument? At first I thought it must have gotten posted to /., but I couldnt find any mention of it there. I've seen links to adequacy articles posted on usenet in the past and I figure you guys send out links to your stories to relevant sites/blogs. Between that and your referer logs you must have some idea where they all came from.

System Power (4.50 / 4) (#35)
by tzanger on Sat Dec 15, 2001 at 09:38:23 PM EST

Out of curiousity I'd love to know if the power of the systems in place is really necessary... Dual P3/700s for serving up pages? A dual P3/700 for MySQL, which 99% of the time is running simple selects and inserts (IIRC)?

I've never set this kind of stuff up before but from my own office networks I've noticed that processing power is hardly necessary except when, heavy processing is required. Hell my main fileserver (over 100 active clients) was a P90 with a killer I/O system until the new SCSI RAID controller required a more up-to-date PCI controller. The database server needed some more balls because the queries are quite complex. The mailserver pushes about 30G/mo but just needs lots of RAM for the spam check; processor power is vastly underutilized even on the P2/233.

This comment isn't meant to be offensive, but rather out of curiosity. What does the processor load look like and how does it correlate to pageviews? I heartily believe in clusters and redundancy; I'd like to know if cheaper (lighter) hardware would work.

by mindstrm on Sun Dec 16, 2001 at 10:40:18 AM EST

I obviously can't speak for K5... but in my own experience, your assumption is correct.

The processor speeds we see today are generally not necessary for many of the tasks we do. THe same goes for home computers.

But why a Dual 850 instead of, say, a dual 500? BEcause.. that's all you can buy. You don't save any money by buying a pIII 500.

by RadiantMatrix on Mon Dec 17, 2001 at 04:55:53 AM EST

You don't save any money by buying a pIII 500.
There's also the issue of controlling your upgrade cycle. If a P3/850 is $30 more than a P3/500, you're better off with the faster machine because (theoretically) your system can expand more before you need to upgrade.

Since upgrades are usually when the most downtime occurs, upgrading less means less downtime too.

The Power Issue (5.00 / 2) (#65)
by rusty on Sun Dec 16, 2001 at 11:09:55 AM EST

This has come up before -- genrally every time we upgrade hardware, someone asks why we need it. :-)

Basically, Scoop is really, really dynamic. If all this was static html pages, we could run it off a single PPro. But to do all the nifty stuff that Scoop does, it has to hit the database really hard.

Processor power is not really the key factor, you're right. Memory is, though, and machines that support a lot of memory tend also to be SMP. Besides which, the more processors you have, the more httpd and mysql threads you can run, and the better off you are. That is, more slower processors are better, for this application, than fewer faster processors.

Right now, one of the scoop boxes has died, so everything's running on a single dual P3 750 with a gig of RAM. On a Sunday morning, the load is around 8-9. We really do need this stuff. :-)

Right; that is database. That's what I thought...

So I ask again, perhaps clearer: Why not use the dual fast-as-hell, great I/O and memory server for the database? Maybe a couple single-proc Celerons or cheap-AMDs just for DB reads (and a move to Postgres, ooh a flame war!) and then a battery of cheap-as-you-can-buy servers for the apache frontends? I've found backplane systems that fit 4 systems into a 4U case... Hell you could fit the image/ad server off of one of the db servers since it'd be all static serving (ad image is selected by scoop and the image is statically selected from the image server)...

Is there any caching done in Scoop to try and keep the 10-zillion-exactly-the-same-DB-hits to a minimum? That is one thing I think /. really got right: frontpage updates are part-static, part-based-on-user, and even has static story views, although I've been bugging them to make the static views "nested" instead of "threaded" so I can read the whole thing when the DB is going crazy. :-)

Of course, there are a dozen ways to do it, each with their own plusses and minuses. I know K5 is ad-funded+sub-funded+any-donations-welcome so spending a pile on hardware is out of the question, which is why I was thinking of the more-cheaper-system approach. Anyway like I said, I was just curious and thought I'd ask. I'm really glad K5 is back. :-)

aside: is it possible to set up a stat page where the readers can see the hits/load/mem/cluster status broken down by time/day? It'd be a great reference just to see how a realworld system works.

Why not use the dual fast-as-hell, great I/O and memory server for the database?

I see what you were getting at. In fact, the dual P3 700s are the slow machines in all this. Only the LVS is lighter-weight. Right now, we have three boxes that are all about the same-- that dual P3 class. Soon, those will all be running scoop, and the database will be on a quad Xeon. Your strategy is right, your standards are just too low. :-)

If we were buying servers, of course, we'd have none of this nice stuff. Luckily, companies like Promicro (plug! plug!) see the adavantage in giving us hardware in exchange for getting their name in front of all of you.

I mean, what we could make do with is one thing, but would you turn down better stuff if offered?

Is there any caching done in Scoop to try and keep the 10-zillion-exactly-the-same-DB-hits to a minimum?

Yes, quite a lot actually. If you pay attention, and can pinpoint when we restart apache, you'd notice that the first few pageloads are pretty slow, but it ramps up rapidly. Scoop caches everything it possibly can. The tradeoff for this is it hogs memory. The more memory, the better the performance. It's almost linear.

About stats: I will try. It would be interesting, wouldn't it?

If that sort of stuff really bothers you (like the OSDN crap bothered me), the logical solution is to do something about it, and get a filtering proxy.

My particular favorite is Proxomitron (for Win32), since it is very versitile and comes with lots of neat built in rules. With a half an hour work, you can transform Kuro5hin into something like this.

I may publish a guide on creating new rules in proxy filters, as to make your favorite websites look better, sometime in the near future.

The only ads that piss me off are pop(ups/unders), and turning off javascript takes care of that. Those news "shoshkels" (or whatever) have the potential to get really annoying, but I don't use IE, so they shouldn't work. Even if they do manage to get them to work on whatever browser I'm using, I'm willing to mangle it's functionality to get rid of them.

Galeon kicks ass as a web-browser, it's got two amazingly cool settings- "right-click, block images from this server", and "settings -> Allow Popups?". A lot of people also like the 'tabbed browsing' feature, but it doesn't quite work with my work-style.

I used to give my friends heck who ran linux, saying "oh, if it's so great for working with the internet, then why do all of the web browsers suck?" Happily enough, some awesome people have done something about it, leaving us with uber-crossplatform mozilla, k-rad K-meleon (browser, file manager, etc...), galeon (it just works), opera (i'd rather pay for beer than not have it at all), and of course our old text-mode standbys, lynx and wget. ;^)

Is that specific orange logo their registered trademark? (I don’t see a TM or an ® on it, nor on the one on their site.) If it were, then I the colors would play a major part in the logo, but it does not seem to be.

by theboz on Sun Dec 16, 2001 at 11:12:33 PM EST

Their logo reminds me a lot of the AT&T deathstar logo too. I think what happened is that someone that works there decided they needed some sort of logo so they opened up photoshop/gimp or whatever and just made something very simple. The orange color looks ok on black, but not on white. When choosing colors for your logo people should pick something that looks good especially on black or white, because while their webpage might have a black background there, their business cards and stationary will have a white back ground, and it doesn't look as professional to keep the logo in a black box.

Of course, I have never done any professional art or graphics jobs, so what do I know? :-)

I've been pushing for FreeBSD for a while now :-) But I think we didn't this time because of threading. Supposedly MySQL doesn't like the threading on the BSD's. So, until the site runs PostgreSQL ( which is after I port it and we find a good reason to move to it, which will be a while ;) or the BSD's change the way they do threading, we're on linux.

At least thats how I understand it.

OpenBSD doesn't do SMP, though (and neither does NetBSD, at least on x86, as near as I can tell), and all the machines in the cluster are SMP. Once they pull their socks up on this, though, I can't say I'll be able to beef too loudly (and may just have to install OpenBSD on my firewall, which is a dual-proc P133, currently running Linux).

But then again, no offense to the FreeBSD guys, but FreeBSD SMP is as close to useless as functional could ever get.

However, the unspoken, and unhinted at even, point of my post was that if OpenBSD fixed their thread implementation to work better with MySQL perhaps the FreeBSD folks, with proper prodding, could adapt said functionality and make the world a kinder, gentler place for open source relational databases.

I'm not entirely sure what the FreeBSD guys are dinking with just now... Maybe they have fixed this stuff in 5.0 (which, from what I'm told, actually does SMP better than Linux, and better than Solaris on x86 rigs)... Of course, 5.0 is still beta (alpha?) so this is all moot.

Heh, since we're on the topic.... (4.00 / 1) (#96)
by Miniluv on Mon Dec 17, 2001 at 12:10:36 PM EST

Here's my experience with SMP on multiple x86 operating systems:

Solaris x86 blows at everything. It's Solaris Sparc with no good features and all the bad ones are even worse. Is it obvious yet that I'm not a Solaris fan?

Linux SMP is decent, but it doesn't scale spectacularly well just yet. They're working on it, and as far as free *nix goes, it's pretty damn good. Based on what I've read on LKML it seems they've still got highmem issues, which isn't unexpected, as x86 memory addressing for large memory configurations is a cast-iron bitch.

FreeBSD Stable/Release SMP is pretty good, scales almost as well as Linux. I've not heard anything one way or the other about large memory configurations, so I have to plead ignorance there. As far as current goes, the SMPng stuff they're working on sounds interesting, but take a look at their release schedule to see why they think they can accomplish so much. We aren't going to see 5.0 as a release until at least the end of 2002, more likely early in 2003 (they've slipped the date by at least 18 months now) and they aren't backporting any of the SMPng stuff.

The one thing FreeBSD has going for it in a huge way is the VM, which is arguably still better than Linux post 2.4.10 (with the Arcangeli VM) including the use once fix that's in 2.4.17-rc1. I've broken several boxes in my lab at work by doing simple things which hit file system caching in a huge way (think "grep -r stuff /") and suddenly memory starvation becomes a huge issue and the box starts oopsing.

If anyone in the K5 management crew is listening, I'd stick with Linux for the time being, as switching to FreeBSD would be more trouble than it's worth at this point.

Maybe... (none / 0) (#98)
by trhurler on Mon Dec 17, 2001 at 12:27:57 PM EST

It might be because FreeBSD's SMP and threading aren't up to snuff. Or maybe it is because it might actually require porting a few things, such as, say, cluster management software, which FreeBSD just doesn't have.

Then again, maybe it is because people who use UPSes as God Himself[tm] obviously intended don't have filesystem problems.

A third possible reason is that FreeBSD has this interesting habit of working only on a (sizable, but largely unstated) subset of hardware. It tends to do interesting things like flat out bomb on other hardware, often because of little hardware bugs that the Linux people wrote workarounds for long ago. Size does matter in a development effort, sometimes. I've convinced FreeBSD to crash for no good reason on at least three different machines around the office, and that's recent versions. Older ones were worse.

Yet another reason may well be "they like Linux." That's a pretty good one, considering that they run the site and you don't.

By the way, I run OpenBSD, and I regard your FreeBSD snobbery as beneath contempt. :)
