@MichaelHampton LOL
 
sigh I wish ext4 had compression. Or some kind of LVM volume level compression option. Nothing seems very snazzy so far.
First person to say "ZFS" gets a pole vault in the keester.

Q: Understanding administrator rights on a machine

Andy MAs a developper I need to create a folder within a customer' server and I need to be sure that they wont be able to access that particular folder's content even if they are administrator or in any other way ! I thought about this particular solution : They create a local administrator account ...

 
@JeffFerland Pest, begone.
@JeffFerland If I saw that a developer of a vendor product was doing something like that, I'd call in an airstrike
 
6:39 AM
I've never gotten why developers are all everyone must learn zee kodes! and not bother to learn basic sysadmin stuff
 
6:53 AM
G'day
 
Incoming shitty question from StackOverflow
 
where away ?

7:35 AM
@WesleyDavid How does getting all of Twitter to tell you the same thing feel?
@WesleyDavid Is "Why didn't you use screen," feeling like, "Why don't you have backups," yet?
 
7:48 AM
@Iain, any similarities between the OP and person that has the accepect answer on this question? Answer was posted and then accepted as an answer one minute later.
 
@tombull89 how did that question manage to last on the site for over a month, I wonder.
 
8:40 AM
morning strangers!
random q, how much do you guys get your glc-sx-mm modules for?
 
9:29 AM
Do you guys ever get people asking questions in your email?
I've had two people in the last couple of weeks (one from Yahoo answers, one from ServerFault) who sent their question to my email address rather than asking on either site.
 
@Ladadadada I have, just once.
Building an image for 16 new laptops - getting the graphics drivers from HP's Website...
 
@Ladadadada I've had one person follow up and I've also had a few mod related emails
 
AMD Video Driver and Control Panel - 485.7MB WTF HP, that's ridiculous.
 
@Ladadadada some people prefer a more direct personalised approach i guess
@tombull89 as much as anyone hate downloading 486MB, during the install pick the driver only option
 
9:34 AM
their control panel is over bloated crap
 
@ColdT I wish there was "driver only" download option - I have an ATI card at home and don't use the control panel.
Oh, wait, it's offering Intel and AMD drivers...how do you know what the machine has, just by looking at it?
 
i think majority wish to have driver only download :(
 
Christ, the network drivers are even worse - Intel, Broadcomm, RealTek and Atheros chips?
 
@tombull89 You mean don't keep an exhaustive library of PCI device IDs in your head at all times? Are you thick or something? :P
 
@SmallClanger I may know a lot of useless information but Device IDs are not my strong point, sorry.
 
9:46 AM
I never buy Toshiba laptops for this reason. They're like HP in that they'll just throw you at a page of ~100 downloads for every device they've released in the last 10 years, with no indication of what you might need for your hardware.
 
driver wise, i think dell has the most sensible options
 
10:07 AM
Why aren't there any SAS HBA's with dual external ports AND internal ports? :(

Q: why allow windows to disable one core?

saber tabatabaee yazdii teach MCITP for students and when describe about Disabling the Devices or Drivers , one of them ask me : why allow windows to disable hardware that need? why windows allows to disable drivers or Devices that Meaningless? like disable cpu? like disabling graphic card? when windows all...

Q: Custom php ini files for IIS7

JaapI have a Windows 2008 Web edition server setup with IIS7.5 and PHP 5.4.6 FastCGI installed. I would like to make use of the user INI files as described here: http://php.net/manual/en/configuration.file.per-user.php I have PHP installed at C:\PHP and the main ini file is at C:\PHP\php.ini. The w...

are questions/answers like that useful ?
 
@Iain: yes and no
self answers are apparently encouraged now
 
@JourneymanGeek you'll get splinters with answers like that
 
10:29 AM
has anyone ever attempted to disable cpu here lol
 
but the answer itself is crappy
 
@JourneymanGeek but is I updated the software and the problem went away a good answer ?
 
@Iain: nope. If that had been a good answer, that might have worked ;p
too localised might work here
 
@JourneymanGeek that's what I think too but I may take it to meta #
 
i think all answers should be detailed and specific or just mods should remove as its a waste of space (almost)
 
10:32 AM
@ColdT: would be simpler to deal with if it wasn't a self answer
 
@JourneymanGeek sometimes, during the process of troubleshooting/reading other answers, you work it out (or something clicks in your head), therefore self answer is valid provided it's detailed rather then 'updated software and went away'
 
Hey @Chopper3 how are you doing ?
 
although not many people would work out and say something like 'found the bug in the next release notes, bug was xyz, so updated software and went away'
 
@ColdT: precisely, but dealing with the answer, and not the question would be messy too.
 
@Iain I've got to admit it's getting better, a little better all the time
 
10:35 AM
@Chopper3 FAB
 
@Chopper3 why on earth would anyone want a clock with that picture as the background and pay 'that much' :|
 
@ColdT I know, great isn't it
 
wish i could see 'qauntity sold:NaN' lol
 
0 is a number
 
@Chopper3 not FAB ;)
 
omg that rabbit just raped the cat :|

11:06 AM
hey guys
@Chopper3 I'd pay money to NOT have that canvas clock anywhere near me
 
ahh troll Jesus

Q: Virtualizing a production MySQL server

posted on October 25, 2012 by Cole

I recently had an issue within vCenter where I could not edit or delete two of my resource pools. Unsure of exactly why this was happening, I decided to do some digging. First, I had noticed that the Users group was added to these resource pools for some reason, and set to Read-Only. I can only assume that someone did this accidentally . (Or at least, I hope.) So now, I’m stuck since no

Q: Creating a raid on MSA60, will it check for bad disks?

lbanzI'm recreating the raid on a old msa60. Would it check for bad disks when I create it? It is three msa60 enclosure with 12bay and 1TB each. I need around 24TB usable storage, what would the ideal raid for it? This is going to be used as a secondary backup and there will also be a tape library att...

 
I'm back, nerds
 
I would not want him designing my 24TB of storage
You know, I've never had to manage big storage. My biggest Nexenta setups are < 16TB.
 
@ewwhite Why can't he just combine the LUNS at the OS level? Dynamic disks, software striping.. whatever
 
@pauska The Smart Array P800 controller (which is period-appropriate for his MSA60), supported 2TB LUNS back in the day. If you update the firmware, it's 8 Zettabytes.
 
well that's an easy task
 
1:03 PM
@ewwhite I had 28.8 raw at $lastjob, but it was significantly less when provisioned
 
but going above a certain amount of TB's are dangerous (raid size)
7x5disk in RAID6 groups leaves one disk for hot spare
21TB raw storage
 
Dan
@MDMarra It was 28.8 on that pic I posted yesterday, oddly enough
 
oh, I didn't think about the actual usable size.
 
@Dan I've been sick the last few days. What was it?
 
Dan
1:06 PM
@MDMarra 4 node P4000
 
Same here
4 node P4500 G2 with 600GB 15K
 
Dan
What's your usable - I did everything NRAID10, so half in the end
 
There were two separate clusters that were both NRAID10. One cluster was configured physically with R10 and the other was R50
So somewhere around 10TB roughly?
 
@ewwhite actually, 5x7disk RAID6 gives 25TB raw storage..
@ewwhite can it use global hot spare disk?
 
yes, it can have multiple global spares.
 
1:09 PM
@Dan NRAID?
 
@tombull89 Network RAID - LeftHand speak for redundancy between SAN nodes.
If you have two storage nodes in a Network RAID10, you basically have a mirrored HA active/active cluster
 
@MDMarra Crikey, okay.
 
So you can lose a whole shelf of disks and still chug along, just with 1/2 the iSCSI bandwidth
 
RAID prevents again issues of disk failure, and NRAID prevents against issues of SAN failure - it would be nice if we had the capacity to do that :P
 
They're really cheap units
4 P4500 G2 nodes with 12x600GB 15K disks each (28.8TB Raw), plus 8 sockets of vSphere standard, plus vCenter, plus 4x DL380 G7s with 2x 4 core and 64GB RAM each was like 80k USD
.edu pricing, of course
That was maybe a year ago
 
1:15 PM
We had money chucked at us for this new school build, but any "new" stuff we need will probably be looked at around 2020.
 
Dan
@tombull89 :(
 
@MDMarra or $25 and a couple of beers at .chopper pricing.
 
Ya, but he does PR for everyone. Sucking the marketing balls plus volume purchasing gets you sweet discounts
 
a lot of educationalists forget that the computers they want to buy today will need ot be supported and replaced one day eh @tombull89
 
Indeed. That lot would set me back six figures, easily (in UKP)
 
1:17 PM
@Dan Our (boss's guesstimate) is for the laptops to last for 5 years before they should be replaced, although it's likely they'll be in use for twice that time.

@RobM Yup. With this new build we got a ton of money to buy stuff, but when we asked for money to cover running costs and damage that got waved off. Luckily we did go for 3 year warranty with everything - which runs out around July so I'm going to have to start reparing stuff myself.
If I'm still around here, that is.
 
Ouch
We do 5 year warranty minimum on everything here
 
16 hours ago, by Peter Grace
"How can I be expected to not snark with questions like this?!?!"
 
And as soon as it's expired, it's pulled from production
 
1:20 PM
@MDMarra Our stuff will be running until it drops.
 
We literally have a shelf full of Cisco 3550-48s and 3560 PoE-24s that work fine but are end of warranty
I'm about to grab a couple and use them for my ccna study when I start that (after I finally finish my MCITP:EA)
 
Can't you get further carepacks for HP? Or after 5 years are they not interested?
 
We don't have HP here, sadly
 
@mdmarra education is often the best place to see "penny wise but pound foolish"
 
The HP talk was about kit purchased at my last job
@RobM Not in education anymore
 
1:21 PM
Oh, sorry.
 
@tombull89 I'm working hard to push for HP blades though, for our new project
 
@MDMarra While we had a lot of money wasted here I'm glad we did get blades and VMWare as it's given me expereince with a production virtualized network.
 
@RobM No, corporate environments are great about that too. All the incentivization for everyone is about short-term profits and revenues, so why consider the long term?
That's the next guys' problem, don't screw your bonuses and raises over it.
 
@MDMarra 5 years is ideal, but I find it very hard to actually furfill 5 years of production on equipment.. look how SAN/servers have scaled only the last two years..
 
@HopelessN00b that's true to an extent but in business, I've usually got somewhere when presenting a waterproof business case for something
 
1:27 PM
@MDMarra any particular reason you're pushing HP instead of Cisco UCS?
 
@pauska I think one thing people here struggle to understand is the speed of progress - they accept that I'm going to replace a server after 5 years, but they struggle to accept just how much different a server that's 5 years old can be.
 
@gparent you still around?
 
@MDMarra So many discounts to be had...
 
@MDMarra: Didn't you know? We are the Sales, Support and legal department for EVERYONE, not just Cisco. — SvenW 9 mins ago
chuckle
 
@pauska Scalability down the road.
 
1:39 PM
@MDMarra please elaborate, this is interesting to me..
 
The interconnects on the UCS stuff are oversubscribed triple (I believe) what the HP ones are and chassis-to-chassis interconnection is much less efficient
At least that's how it was demoed to us by an independent vendor that resells both
Maybe it was Dell that was triple oversubscribed and UCS was 2x
Basically, HP's interconnects are oversubscribed 2:1, the next closes competitor was 4:1 and everyone else was higher
 
@MDMarra But the way you'll be using the system, it don't matter!
 
2:1 doesn't matter, but when you start getting 9:1 it starts to a bit
 
Buy the HP gear from my guy, save a shitload, look like a hero.
 
Heh, we're already working with an integrator/reseller
Getting the chassis and virtual connects for free
Assuming that's the way we go
 
1:45 PM
@MDMarra Then you see the server prices...
 
They're pretty reasonable
 
Chassis and the Virtual connects are cheap.
 
pfo
anyone here that has adopted NFSv4 already?
I'm currently in the planning and prototyping phase
 
1:55 PM
Anybody care to tell me what EXACTLY is in these Google racks? This Datacenter is actually up the road from me. I know they are servers and switches, but the components look "open" to me, and I'm trying to grasp what's in, say, a single rack exactly component wise. google.com/about/datacenters/gallery/#/all/20
 
@TheCleaner google has their own equipment custom-made. Looks like how you say, they're motherboards on a tray.
 
yo Geeks, what a mad few months
 
@PeterGrace - interesting. I was always told over the years "make sure the lids are on the servers for proper airflow and cooling." I like their pics...makes my datacenter look weak by comparison...
 
@TheCleaner Yeah, and this would be why they run their DCs hot and have an expected failure model and all that. They use cheap, barebones hardware and make up for it in software
 
@TheCleaner It all depends on your environment
If you have a datacenter all to yourself, you're free to set the requirements on how it operates so you can do other things that might not work in a colocation facility
 
Dan
2:09 PM
@TheCleaner By the time you're at Googles size you're making your own rules, really
 
They use commodity hardware too for most things
 
Dan
Or rather, making the rules if you're very succesful!
 
A lot of it isn't server-grade because they mega super duper cluster pool the shit out of everything
 
@Dan you beat me to them. I was going to say they make the rules and people follow in terms of Data Center setup. Ify our big enough to build customer DC's you can do what you want.
 
Yay Autodesk: How to transfer a license from one machine to another. Instructions in a 15 minute powerpoint video...
 
2:10 PM
why is this serverfault.com/questions/442111/… not application debugging 101 ?
 
@MDMarra yeah, I heard that at some point...that each "server" is quite basic and each single node is no loss at all if it fails. The pics of their robotic backup library is impressive. That would NOT be my dream job. "Hey Cleaner...earthquake swallowed the whole place...go grab the tapes" :(
 
Heh
 
@Iain It is. But it seems to be coming from a developer, and developers are great at turning a 101 or remedial-level topic into a doctorate level issue.
 
Have you seen the video of the shipping containter datacenters?
It's a bit old now but still cool
 
Negative. I did see the one of (crap can't remember the company) that built identical redundant datacenters on the same campus. A bank maybe? Pretty impressive....massive.
 
2:15 PM
@TheCleaner Yeah, I'm honestly surprised that they have a tape library and aren't doing the backblaze thing (consumer grade xTB drives in RAID on consumer grade cards and all clustered together, expected failure, etc.).
 
I'm sure they disk-to-disk plenty and tape is just long-term archival
 
@HopelessN00b some auditors are cocks (see the S/F post) and demand tape. Also tape last longer.
 
It's probably not traditional disk-to-disk like we think either
 
Dan
I wonder how many IOPS you could get out of a SAN built with hundreds of 3.5" floppies
 
I guess if you have software in place to NOT delete anything, period, then you can simply add more and more disk. It would make point in time backups almost pointless if that were the case. Impressive, however they do it...
@HopelessN00b - backblaze...interesting...reading a blog on it now...
 
2:21 PM
@Dan wouldnt it be IOP/M :P not /S
 
@t1nt1n This is true, but I've had good luck telling auditors to get on board, and/or eat shit. What's this post, though (the my security auditor is an idiot one)?
 
Dan
@t1nt1n Haha, probably true
 
Shopping question! Where do you guys order your cat6 cables from?
 
CDW
 
Honestly, I just feel safer with actual tape backups. I'm a little old fashioned though.
 
2:23 PM
@PeterGrace I get tripplite cables... and source them for $1-$2 each.
 
@MDMarra Ya know, we have some CDW cables at the colo and I just fthought they felt flimsy.
 
I go direct....
 
I like monoprice's build quality but Zypher is not a fan of their boot.
 
I dislike all boots on cables
 
as does he
 
2:24 PM
i just crashed a dymo label printer wth..!
 
DOWN WITH THE BOOT, LONG LIVE THE CLIPPY PART!
 
I do Tripp-Lite - Here's an example part # N002-007-BL
 
I honestly don't give a shit, I keep a pair of scissors at the colo and I use it as an extraction tool.
 
no boot, molded, flexible.
 
@PeterGrace Bought from CDW, made by Belkin. Get the snagless molded kind so it's easy to push the tab.
 
2:25 PM
@HopelessN00b yea the my security guy, all the old timer S/F people will have seen it
 
Dan
Right, I'm getting out of here - I'll probably see y;all when I'm on a train!
 
@ewwhite those actually look really nice.
I wonder what colors I can get 'em in
 
I've had enough clips stab me under the thumbnail when trying to remove a booted cable to last me a lifetime.
 
@PeterGrace I know... about six colors.
 
@Dan later
 
2:25 PM
@t1nt1n Well, that's the answer to stupid auditors. Get on board and grow a brain or lose your job. Actually tends to work pretty well.
 
these are the only ones that don't leave me hurting after a day of patching.
my source is CDW (in a pinch) or one of my other suppliers...
 
ooh, they come in all sorts of colors
 
@HopelessN00b so true.
 
but at volume, they should be < $2/cable
 
Alright, fuck you too, SO.
Thank you for reviewing 20 Late Answers today; come back in 9 hours to continue reviewing.
 
In fact, @peter, I was thinking about SE and your hardware sourcing. You guys should leverage my services/volume.
 
$7 per cable erp according to that site tho
 
@ewwhite They're a Dell shoppe.
 
@ewwhite It'd be a tough sell with us already so deeply entrenched with CDW. Our sales rep practically brought his toothbrush over.
 
@PeterGrace - typically CDW although most of the time we end up making our own. We tend to use blue for patch cables, purple for panel to jack, white for voice, green for KVM, and of course orange for fiber.
 
2:29 PM
 
On the workstation switches/panels: Yellow - Clean Access VLAN, Black - non-Clean Access VLAN

On servers/infra: Purple - infrastructure to infrastructure, yellow- servers, green - T1 into our voice gateways and fax servers
 
Yeah, we got a color scheme already but don't actually have the cables yet
 
@PeterGrace @chriss I don't just deal in HP. I have access to all of the major distributors and definitely have a great source in NY to handle the types of things SE needs. And yes, at better-than-CDW pricing.
(except for Cisco shit...)
 
Do you have a pandiut cable labeler?
Because if you don't, you should get one
They are fucking awesome
 
haha, I have a panduit cable comb at the office, that thing's cool
 
2:32 PM
@MDMarra I have this bad-boy from Brother. brother-usa.com/ptouch/…
it scares people
 
@ewwhite hey, if you wanna put a quote together I'm totally willing to put you in the running
@ewwhite you got a source for colored power cables?
 
Yes...
and yes.
@PeterGrace Let me know what you need.
and for power cables, I only do black and green in my installations... but again, they're tripplite
 
We use the Brady IDXpert labeler. Works well, lots of color and types of labels
 
@ewwhite Yeah the Pandiut is similar
 
Yeah, we've got a Brady IDXpert too.
 
2:34 PM
Does it make labels that lay flat on the cable and are protected by a clear piece of label?
 
yes.
Self-Lam.
 
That shit is required
 
That's the codeword for it.
 
haha
self-lam? got it
I didn't know what I was missing until I started using that
 
the IDXpert is $$$ but the quality of the unit is off the charts
 
2:35 PM
Yeah... Just change the type of label. But the nice thing is being able to steal normal Brother P-Touch cartridges from the office staff when you're in a pinch.
 
I'm a big Pandiut fan lately
We got a Panduit rack for our Nexus
That thing has so much space, I could move in.
 
@ewwhite Tripplite only lists 3, 7, 14 foot lengths. Are there any other sizes or is that all they make?
3ft almost seems too small if you think about wires going out to wire management and then going down to a server then entering a dell cable arm
 
cue the cable arms are dumb discussion that is about to happen.
 
I've done 1, 2, 3, 5, 7, 14, 21...
Scrap the Dell cable arms... and use vertical PDUs with 1ft and 2ft power cables to mate to the respective A/B PDU.
 
@JeffFerland Feels good, man.
 
2:39 PM
@Nonapeptide SCREEN, CAT, SCREEN
 
@PeterGrace Just sayin... my guy is in NY. I definitely don't pay what other people seem to pay for gear (except for @Chopper3), and I'm trying to expand to provide services to other organizations.
CDW is here in Chicago... no East Coast warehouse, and it's... bleh. I only go there when I know I can drive 20 minutes and do a will call pickup.
 
Mornin gents.
 
@ewwhite I'm not really in the role I'd like to be in on the team. I can't really choose vendors.
 
@ewwhite Love my big old PTouch labeler. Fantastic kit.
 
@ewwhite it agitates me slightly coming from being the top banana somewhere and joining a "no bosses" team
 
2:45 PM
@MDMarra Schluuuuuurp
 
when you're used to being a boss and tenure is the only indicator of your pecking order it's pretty tough to get things done
 
@PeterGrace No worries... In my new job, I can't choose vendors either...
Supermicro... eww
 
@PeterGrace It's a perk of being a one-man-does-it-all. ;]
 
@PeterGrace Speaking of, is Kyle leaving?
 
Haha, not as far as I know? What made you think that?
 
2:47 PM
Well, he moved to FLA and shortly after you guys posted an ad for a Sr SA, right?
I put 2+2 together haha
 
Naw, just working remotely.
 
He was a remote worker in Boston too
 
Yeah, I know
 
he just moved to be closer to his in-laws so his wife could tend to them
 
It was more the job posting
 
2:48 PM
@MDMarra Kyle does Networking IIRC; and the job ad seems to be more for a Web Admin.
 
Naw, we've just got so much shit to do and not enough time to do it
@ChrisS Kyle does the networking portion of the interviews but it's not his core competency per-se
George, Kyle, and I all three are senior level generalists, either one of us can sit down in the other's chair and keep truckin as if nobody left
 
@PeterGrace Hiss!
 
@ewwhite what, didn't do so hot on the networking interview? :)
 
@PeterGrace OIC. Good to know you guys have personnel redundancy
 
@PeterGrace I think he said that I was unsuitable for that type of work.
 
2:50 PM
@ewwhite that's extremely impolite of him to say...
 
Well, implied... not those words, exactly.
but I don't know jack about databases or the deeeeep internals of networking. But obviously, I've done it.
And in some crazy environments, too.
 
Realize too that we were hiring for a pretty advanced position. Not to make you feel like you suck or anything, it's just we're trying to get someone who has a certain baseline of knowledge that we don't have to train-up
I didn't interview you so I couldn't say for sure, and I wouldn't want to cast doubt on Kyle's ability to interview, but the way things work is that any of the senior admins have veto power on a hire/no-hire. If any one of us has any doubts whatsoever, we are obligated by policy to say no-hire.
 
No, it wasn't a big deal. I was on my way to NY for interviews. It shook my confidence for a minute, though.
 
Joel is extremely selective in his hiring process
 
Oh, it was just a conversation, not an interview.
 
2:53 PM
Yeah, I don't really know how that went down -- it would have been nicer to have you in the office for lunch and actually have done some semblance of an interview
 
heh... I'll roll by the next time I'm in NY.
 
You're always welcome! :P
 
And convert you to HP, etc, etc, etc.
 
Joel actually joked about giving high-rep users on trilogy sites an access card to come up for lunch whenever they're in NYC
Hah, don't need to convert me, I'd love some C7000 chassis
 
were you talking to me?
 
2:57 PM
@pauska Well, you jogged my memory... There's RAID 50 in hardware for that controller.
no, to the OP
Oh, my bad... it doesn't
 
ah ok
