WhoWhatWhen
up_the_ironsI like using Twitter because it's completely separate from us, so even if our LA data center was nuked, I could tweet that fact and everyone would know ;) [00:06]
erraticassuming you werent vaporized along with LA
oh dude that reminds me

[00:19]
BryceBotDead Hand (nuclear war) :: Dead Hand (Russian: Система «Периметр», Systema "Perimetr", 15Э601), also known as Perimeter, was a Cold-War-era nuclear-control system used by the Soviet Union. General speculation from insiders alleges that the system remains in use in post-Soviet Russia. An example of fail-deadly deterrence, it can automatically trigger the launch of the Russian intercontinental ballistic missiles (ICBMs) if a nucle [00:19]

up_the_ironsbrycec: no [00:22]
brycecWell maybe he should, in case Los Angeles is wiped off the map :P [00:22]
mercutioi think of los angeles was wiped off the map it would be in the news
and people would know about it :)
[00:23]
up_the_ironsLOL [00:23]
erraticheh [00:23]
brycecBut they might still assume their VPS and colo'd machines are okay, safe inside a datacenter... [00:23]
up_the_ironsbut the point is well taken; we should have human RAID1 [00:23]
erraticbrycec: hahahahahah [00:23]
mercutiobrycec: they might be :) [00:23]
erraticdespite however peppered in radioactive fallout [00:24]
mercutiothey'll probably still keep going for a little while at least
i don't know for sure
[00:24]
erraticmay cause a few bit flips but no big deal [00:24]
mercutioaren't things moving from radioactive to chemical weapons? [00:24]
brycecNever know until we try it! #NotAdvocatingGlobalThermonuclearWar [00:25]
erraticyes zombies
world war z inspired them to do things right because they saw the mountain of zombies and were like oh shit thats a really good idea, we should do that
I hear the book was like a completely different story
I haven't read it before though
[00:25]
up_the_ironslol [00:26]

brycecbrycec lost connectivity with his ARP Metal box :/
[and is now figuring out if it's a box issue or ARP]
[01:39]
up_the_ironsbrycec: what's the box label? [01:40]
brycecstl21
last I "heard" from it was ~15 minutes ago
(And I don't want to fight the IPMI battle, but looks like I'll have to)
[01:41]
up_the_ironsI'm in our cage right now. Took a look at it. Seems alright.
But I can judge only from it's lights
[01:42]
brycecheh, thanks for looking.
Was running md5's on some big files, so could've choked on IO I suppose
[01:43]
up_the_ironsif you'd like a hard reboot at some point, just lmk [01:44]
brycecThanks - IPMI works so I can reboot if needed [01:44]
up_the_ironssaves you having to push the IPMI power button
ok cool
[01:44]
brycec(SOL doesn't, but I don't remember if I set that up) [01:45]
up_the_ironsSOL won't work unless you set it up, yeah
or rather, it'll work, but if you don't have anything talking to the serial port, then...
[01:45]
bryceclol I know
brycec is now hating on javaws and its propensity to randomly pick up Firefox's proxy settings
[01:46]
up_the_ironsouch [01:47]
brycecbut only *some* of the Proxy settings, totally ignores the "No proxy for" settings

up_the_irons: Is the IPMI NIC separate from the dual-GBE ports?
[01:51]
up_the_ironsbrycec: yes [01:54]
brycecHm. I was thinking unplugging the Internet from it would allow it a chance to catch up, but probably not. I'm probably better off pushing the reset button :( [01:55]
up_the_ironswell i can unplug the nics if you like ;) [01:57]
brycecI just sent reset ;)
But thanks for the offer/willingness
[01:58]

***gizmoguy has joined #arpnetworks [02:05]
up_the_ironswhat do you have running on top of it, if you don't mind me asking [02:05]
brycecProxmox
(I don't mind)
[02:05]
up_the_ironshappen to have a lot of VMs, or?
mercutio and I are actually building a Linux / ZFS box for VMs...
so your experience scares me ;)
but we'll have 96GB RAM
[02:05]
brycecAnd in Proxmox, a variety of things: servers with databases, web stuff, mail and dns backups, Splunk, etc. But yeah the flexibility/control/cost is important.
I love ZFS absolutely, but I wouldn't really recommend running mission-critical applications on Linux-ZFS. It's not perfect, it has its periodic quirks.
[02:06]
mercutiobrycec: anything in logs? [02:07]
brycecOh and without question, SSD at least for a cache and logging vdev. [02:07]
mercutiobrycec: over allocating memory is the biggest concern with zfs atm
if you have a reasonable amount of headroom you're fine
[02:08]
brycec(Not that I have an SSD in my Metal box, but I wish I did :p it makes a huge IO boost) [02:08]
mercutioon older versions of zfs it's advised to raise /proc/sys/vm/min_free_kbytes [02:08]
***jelleke has joined #arpnetworks [02:08]
mercutiossd caching doesn't help much except for metadata ime
with zfs at least
you use up ram with the tables as well
[02:09]
brycecI'll check into exact memory usage in the morning [02:09]
mercutioare you doing l2arc bryce? [02:09]
brycecMost recently I setup a box with a pair of 1TB drives in zfs-mirro. Performance was abysmal once the RAM buffers filled up. Slap in a cheap SSD and the thing soars now.
Yeah
(Also RAM usage dropped once the cache vdev was added, for obvious reasons)
[02:10]
mercutiobrycec: how big is your l2arc? [02:11]
***ant has joined #arpnetworks [02:11]
brycecOn that system, 50GB, <1GB usage last I checked. [02:11]
mercutio<1GB usage heh
you may as well use zfs set secondarycache=metadata
but i'd go for smaller l2arc than that on 16gb of ram
[02:11]
brycecThe machine in question (with the SSD) only has 8GB RAM actually
[Not to be confused with my ARP machine tonight)
[02:12]
mercutioahh
yeah i've seen l2arc be a problem with memory
[02:13]
brycec[ARP machine has no l2arc, so things can get sticky) [02:14]
mercutioahh
brycec: i hit some serious performance deficits when i was trying to test low memory usage to eradicate caching :)
problem is with a 48gb server using hard-disks it takes ages to benchmark when you have to go above capacity
so i tried something silly low
2gb i think it was
[02:14]
***Seji has joined #arpnetworks [02:17]
mercutiobrycec: my home linux box has 16gb with zfs
doesn't seem to be a problem
and that's with chrome etc running on it
and with more ram around that i had earmarked to upgrade with
mercutio doesn't like rebooting :)
i don't think 16gb should be in the generally difficult carea
area
[02:19]
brycecLike I said earlier, was doing heavy IO so apparently the ARC and everything else were in contention and before I knew up 6GB of RAM went out the window. [02:21]

it was connecting and authing but nothing was coming up.

so close and yet so far
I dont really have a choice but to give it up at this point because I cant afford that
not to mention what good would it really do having been a ketamine/mxe user in the past, its temporary.
[22:36]
and I'm pretty sure the last thing anybody wants or needs is a scathing suicidal nutcase like me so I'm done and I need to find what really makes me happy which is not this shit [22:43]

erraticI dont think anybody here can relate but thats okay you don't want to and I don't want you to either but yeah I'm I think I'm giving up everything
my feelings are pretty uncompromising about this
[22:57]
I just want to live my life and be happy and be a woman and my interests are not aligned with what the "average" customers interests (eg: create-saml-provider) are
fuck an mfa device
``aws iam help'' what do you they need me for
heh, saml
AbstractSingletonProxyFactoryBean
rolls eyes, http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/working-with-templates-cfn-designer.html meh!
I'm way more interested in algorithms https://gist.github.com/cloudkitsch/a214ca4e0467ff2a2db968ecca6cbe3a
but at the same time I dont care about money either because it doesn't make me happy
so fuck being a quant
I'm happy to do it for somebody else who would appreciate it but my interests are skin deep in the thing
