I got a call one day working as a cashier at Wal-Mart asking to do an interview for a position they couldn't give too many details about

So either I'm not as bad as I thought, or the other candidates are way worse.

agreed to the interview, signed some forms, drove down here, and met the person that would be my boss

6:12 AM

Also, it's 3am and the 48hr-hackathon starts at 9am. I should probably go to sleep.

interviewed horribly, talked to him afterwards over a cigarette

let him know I was horrible with interviews, we swapped war stories, and I got a call before I was in my car letting me know they wanted to hire me

nice

go sleep

I had an interview yesterday. Went pretty well.

hope you get it

6:14 AM

@Rikai I am packing. And installing dual-boot fedora on my gaming laptop

@Sathya congrats, good luck!

<3 fedora

@ThatBrazilianGuy thanks :)

NetworkKingPin

@ThatBrazilianGuy dont have too much fun and @Sathya Goodluck!

@Rikai Yeah, I have experience with Ubuntu, Mint and Fedora. I use Fedora daily at work.

@NetworkKingPin I think I'll have lots of fun, stress, freaking out, and redbull

and lots, lots, and lots and lots of !!noidea

@NetworkKingPin thanks!

I started with Ubuntu, moved to Debian, hopped a few distros, and now my main server uses Fedora, I have Fedora in a VM on my main laptop, Fedora as the OS on my backup, and I plan on installing it on my Pi

@ThatBrazilianGuy have fun!

@Sathya I will, thanks :D

If our project gets picked ~~I won't shut up about it for days~~ I'll let you guys know :)

I actually like Debian alot. Started with Ubuntu years ago aftere hearing it from my uncle. Picked up a Fedora Book from a friend and the joy just kept coming.

Actually I kinda feel good about it cause I got lost.

6:18 AM

I had only casual experience with Linux and used mostly Windows at home. Now I have been using Linux daily at work, both at my workstation and a handful servers, and gradually less and less Windows at home.

Suse, ubuntu...

fedora and ubuntu now, ubuntu for servers, fedora on the desktop

Last month I activated a new Win8 install and all the time it's "Oh god, how did I put up with it at all"

apt / yum / any pkg manager >>>>>>>>>>>>>>[insert infinite here]>>>>>>>>>>>>>>> windows

@JourneymanGeek Is that before or after tax?

@ThatBrazilianGuy Until you get stuck in dependency hell and wonder how on earth Linux still has that problem in 2016.

(FYI, Windows pretty nicely solved that with SxS in Vista)

I think there's no tax for that pay level

Most tax here is GST or property based

@Bob I think I only had that once.

It was fun when my file server ran out of space and had 0 bytes free and apt stopped working, including for removing pakcages.

6:22 AM

@ThatBrazilianGuy Put simply, having package repos only as long as the main repos have everything you need.

As soon as you start needing anything from a third-party repo, you're screwed.

nah

just add the repo

Maybe not right now, but good bet something will break down the track.

remove /etc/ and it'll speed ya right up

I.... Must... Sleep...

@Rikai Yea, sure, tell that to my broken system from libguestfs-tools having updated dependencies. Or tell that to the ZoL module not working with the SPL version in the main repos.

Never mind glibc compatibility.

Oh, it might work at first. In fact, it probably will.

A year later, you run a routine upgrade and everything breaks.

Everything.

6:24 AM

I'll spend 3 days away from the wife, and instead of appreciating my few last hours with her, what the hell am I doing here with you guys? >_<

@Bob heh, that's one of the reasons I tend to stick to stock repos as much as possible

I blame the @JourneymanGeek cult for brainwashing me.

bye

bye. YOUR DOG DEMANDS IT.

@JourneymanGeek That's why I said it's mostly (not even completely...) fine if you stick with the main distro repos.

But I've run into problems where upstream bugfixes aren't incorporated.

But I also needed that bugfix.

@Bob I'm pretty certain the issues with phoebe II was ... fedora 23 ;p

6:27 AM

But the updated versions are linked against newer dependencies!

Then you go to build from source.

tho, the new setup is relatively immune to that. At the cost of running a beta OS.

ffs.

I might be juuuuust a taaaaad bitter over ZoL shitting itself on upgrade.

And having to spend a whole day trying to get a server back up because of it.

Let's not forget the libguestfs-tools mess that required a snapshot restore.

lol

Yeah, I'm sticking to ext for now ._.

I'm keeping an eye on btrfs but after the time kernel broke for it, and the lack of common, easy tools for managing, it can wait

Jun 9 '15 at 23:53, by allquixotic

ext4 eats your data and doesn't know it; xfs just doesn't eat your data (ever); btrfs eats your data and knows it (and is proud of it); and zfs doesn't eat your data and would know it if it did :D

:P

@Bob but the data on that system's not critical ;p

6:36 AM

@JourneymanGeek I'm using ZFS there for the raidz1 and the snapshots

@Bob heh, one of my longer term plans is to try to get a freebsd/zfs box up 'properly'

but of course $$$$

Pi that up

lol

HP microserver!

@Rikai ZFS on a Pi is simply insane

or something in a HAF XB

@Rikai properly

6:39 AM

@JourneymanGeek You can probably rent a SYS server pretty cheaply to play with, I guess.

Or a Kimsufi one?

SYS is 56 for a decent one

@Bob I don't need a ton of storage somewhere else tho ;p

@JourneymanGeek It's still a reasonably easy way to get something quick to play with, I suppose.

Depending on whether you want to do multi-disk or not.

@Bob true but most of my plans revolve around hardware

and I do want a large chunk of storage on network

Hm.

Can't really cram much into those NUCs

Pi is, again, insane (nowhere near enough ports/throughput/RAM)

6:44 AM

1.2Ghz quad core, 1GB of RAM

@Bob the 5x5s might work

NUC's problem is case and power actually

@Rikai Y'know what one of my pet peeves is? People who quote CPU specs by clock rate and core count.

you'll be fine

promise

That "1.2 GHz quad core" is, what, Cortex-A7s?

Oh, they're up to Cortex-A53s now.

Sliiiiightly less terrible.

RAM would be the big blocker.

@Rikai big issues here are I/o - to do ZFS right you need multiple drives including a SSD and ram.

6:47 AM

ah, I see

You're recommended to have 1 GB RAM per TB of disk.

4 GB total is the recommended absolute minimum.

wow

ZFS also benefits a lot more from single-threaded performance.

So quad-core doesn't mean much. What you really need are particularly powerful cores.

Cortex-A53 doesn't really fit there. Heck, Silvermont doesn't either.

For a home NAS, it probably doesn't matter as much apart from being a bit slow.

But the RAM requirement is pretty important.

A large part of ZFS is the ARC... and that's not gonna do much good with low RAM.

@JourneymanGeek The SSD (L2ARC, ZIL) isn't as important, depending on what you do.

@Bob I'd want dedup

IIRC you pretty much need it (or an insane amount of RAM) for dedupe.

But as long as you aren't using dedupe (and general advice is not to use dedupe) then that's not necessarily all that useful.

6:51 AM

In theory if I upgrade nyx, the motherboard on nyx might be perfect

maybe top off the ram.

Not very energy efficient for 24/7 running tho

@JourneymanGeek For dedupe you're probably looking at 20 GB of RAM per TB of data...

o0

I thought it was 1 for 1.

Nup.

1 for 1 is without dedupe.

That's why almost no one uses it.

The memory requirements are insane.

You could push much of it to L2ARC but then you'd need a high-performance SSD.

TLC isn't gonna cut it there.

At the end of the day it's probably cheaper just to get more HDDs and expand the storage rather than deduping...

@JourneymanGeek The problem is 1 TB of storage is something like 5 GB of dedup table space which is capped at 1/4 of ARC which is 20 GB of ARC.

Here it is. constantin.glez.de/blog/2011/07/zfs-dedupe-or-not-dedupe

heh

The price calcs are off cause 2011

Hm. Actually apparently if you're pushing it to L2ARC you don't need to worry about the 1/4 cap. So only 5 GB per TB there.

But performance is gonna suck on a TLC SSD still.

6:56 AM

true

(the only TLC SSDs I have are the samsung 730 on my dad's mini 10, and the 830 in my laptop)

@JourneymanGeek Didn't you have an 850? Or was that Pro?

850 pro

A: ZFS: will RAM shortage cause trouble?

Ah.

@JourneymanGeek

Don't do it. Dedupe on ZFS is bad news if you haven't planned well for it... What can happen? Your system can slow down considerably in certain operations. Holding the dedplication table in RAM isn't the best use of resources. Your system can stall for DAYS if you delete data or filesystems t...
