[00:05] <daftykins> ;]
[00:58] <m0nkey_> this mdadm array is kicking my ass still
[00:59] <m0nkey_> fastest speed i've seen is 5MB/sec
[00:59] <m0nkey_> i'm doing random writes
[00:59] <daftykins> :(
[00:59] <daftykins> how'd mounting it from a live session of 7 work out?
[00:59] <m0nkey_> it's now on ubuntu 16.04
[01:00] <m0nkey_> no difference in speed between centos or ubuntu
[01:01] <daftykins> what block size?
[01:04] <m0nkey_> 512
[01:05] <m0nkey_> 2000398934016 bytes / 1953383488 blocks (md0) / 2 = 512
[01:05] <daftykins> hmm bit large
[01:05] <m0nkey_> thats bytes, not K
[01:06] <daftykins> ah
[01:06] <daftykins> if they were advanced format disks, that'd be screwing you up
[01:06] <m0nkey_> both my hw_sector_size and physical_block_size is 512
[01:06] <daftykins> some can mask that though
[01:15] <m0nkey_> re-formated the filesystem, forcing 4K, i've seen a slight increase in writes, from 4MB/sec to 6MB/sec
[01:15] <m0nkey_> Any way to force 4K sectors in mdadm?
[01:16] <daftykins> i forget, is it a host or a KVM guest?
[01:16] <m0nkey_> KVM host
[01:16] <daftykins> hmm well without any running the virt tech should be irrelevant
[01:17] <m0nkey_> doing a simple DD
[01:17] <m0nkey_> Hitting 20MB/sec
[01:17] <m0nkey_> KVM tops out around 6
[01:18] <m0nkey_> 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 52.3285 s, 20.5 MB/s
[01:22] <m0nkey_> How'd I force it to build using 4K?
[01:22] <daftykins> you are using a blocksize though right? on the dd command
[01:24] <daftykins> no idea there, when i've done RAID it's been for large files so i've done 64KB or larger
[01:50] <m0nkey_> i've destroyed the array and testing with a single disk
[01:50] <m0nkey_> see how kvm performs on writes with that
[01:51] <m0nkey_> interesting
[01:51] <m0nkey_> with a single disk, it's slow
[01:52] <m0nkey_> testing the second disk
[01:55] <daftykins> o0
[01:55] <m0nkey_> wow, even with the second disk, it's super slow writes
[01:56] <m0nkey_> maybe it's my controller :)
[01:56] <daftykins> what is it?
[01:56] <daftykins> maybe there's a bad driver, mmm
[01:58] <m0nkey_> whats the command to see that again?
[01:58] <daftykins> lspci ?
[01:58] <m0nkey_> 00:11.0 SATA controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode] (rev 40)
[01:59] <daftykins> hmm so it is just chipset based most likely
[01:59] <daftykins> i thought this was like, a workplace server
[01:59] <m0nkey_> heh, no
[01:59] <m0nkey_> just some home crap box
[01:59] <daftykins> ah
[02:00] <m0nkey_> Ubuntu doesn't do ZFS as a root filesystem, right?
[02:00] <daftykins> can you ID the motherboard? maybe that'd give some search results
[02:00] <daftykins> mmm, pass
[02:00] <m0nkey_> Base Board Information
[02:00] <m0nkey_>         Manufacturer: MSI
[02:00] <m0nkey_>         Product Name: 870A-G54 (MS-7599)
[02:00] <daftykins> sounds right for how it used to be, but no idea on current
[02:00] <m0nkey_> it's an old AMD board
[02:01] <daftykins> AMD® 870+SB850 chipset
[02:01] <daftykins> mmk
[02:01] <m0nkey_> Yeah, wasn't a brilliant board to begin with :)
[02:02] <daftykins> can you check out what SATA configuration modes you have in BIOS?
[02:02] <m0nkey_> From memory, ACHI, IDE and RAID
[02:03] <daftykins> mmm, apparently AHCI is really bad on that chipset
[02:03] <m0nkey_> oh
[02:03] <m0nkey_> okay
[02:03] <daftykins> i see talk of folk moaning about AMD's AHCI support
[02:03] <m0nkey_> I'll try that soon
[02:03] <m0nkey_> Got to put my two girls to bed
[02:03] <m0nkey_> brb
[02:03] <daftykins> it's a total longshot but yeah, maybe in IDE mode it'll do something different :D
[02:03] <daftykins> roger that
[02:18] <m0nkey_>  ok they're in bed
[02:20] <m0nkey_> and i'm in IDE mode
[02:20] <daftykins> dun-dun-duuuuun
[02:20] <m0nkey_> kicking off a vm install
[02:21] <m0nkey_> ok, write speeds are up
[02:21] <m0nkey_> avg 10MB/sec
[02:21] <daftykins> :/
[02:21] <m0nkey_> that's a slight improvement
[02:21] <m0nkey_> better than 4MB/sec
[02:22] <daftykins> is that install just the quivalent of a debootstrap kinda process on this RAID 1, then?
[02:22] <daftykins> *equiv
[02:22] <m0nkey_> yes, i guess so
[02:22] <m0nkey_> i'm booting the debian install iso
[02:22] <m0nkey_> and when it starts the install it slows to a crawl
[02:24] <daftykins> i've actually got a setup here that i could try the same on and see if it's bad at the same stripe sizes etc, over the weekend
[02:24] <daftykins> probably be moot due to not having the same chipset though
[02:25] <m0nkey_> it's probably because of crappy chipset and drives
[02:25] <m0nkey_> when I do a ZFS rootfs, I can add a SSD as a write cache, so it's fast that way.
[02:26] <daftykins> i saw something about using a cache drive with mdadm too whilst trawling around
[02:27] <daftykins> i've not used mdadm before so it could be fun anyways :)
[02:27] <daftykins> ok gotta sleep for now, ttfn \o
[05:40] <mappps> urgh time of yr its hard to sleep..hot and sticky ;[
[05:50] <m0nkey_> whats the temp there?
[05:54] <mappps> 24c
[05:54] <mappps> 66% humidity
[05:55] <m0nkey_> that it? :)
[06:00] <mappps> heh
[06:00] <m0nkey_> I was expecting 32C+ :)
[06:00] <mappps> feels sticky and cant have my window open as building new flats nex door
[06:00] <mappps> so its hot ;[
[06:04] <m0nkey_> it's 19C, feels like 24C here this evening. 83% humidity.
[06:04] <m0nkey_> It's actually been a cool day
[06:04] <m0nkey_> Most of the week it reached 31C
[09:22] <brobostigon> morning boys and girls.
[10:55] <diddledan> wow. I missed the whole dallas thing on thursday
[10:55] <diddledan> apparently the police used a robot to end the violence in a "show of lethal force" (as someone wrote)
[10:57] <diddledan> while I appreciate that it was the least dangerous way to end the conflict with fewer casualties I can't help but think about skynet
[11:03] <zmoylan-pi> because they didn't have the area secure?
[11:06] <zmoylan-pi> in next hostage situation, a drone, police, media or private will escalate things after this
[11:11] <zmoylan-pi> even worse, you'll probably start hearing of more paranoid individuals shooting down drones as they think the police are out to get them
[19:22] <diddledan> wtf? this is twisted: https://youtu.be/sg0D1PpgCXs
[19:23] <diddledan> transformers go "politically correct” with optimus turning female
[19:23] <diddledan> bit of swearing and shooting each other
[19:38] <daftykins> that's... weird
[19:39] <daftykins> also, double clicking desktop icons kills kittens
[19:39] <zmoylan-pi> thats default in winme
[19:41] <daftykins> hmm actually i had a massive mental fail there, that IS default :D
[19:42] <zmoylan-pi> it's the active desktop shenanigans... i spent a large amount of time turning that off in every pc i encountered
[19:42] <diddledan> I always knew you were a nutjob
[19:43] <zmoylan-pi> just me and my collection of singing potatoes
[19:43] <diddledan> zmoylan-pi: because who wouldn’t want html everywhere?!
[19:43] <daftykins> yeah, i couldn't stand that rubbish
[19:43] <daftykins> seems i'm as confused as megatron today
[19:43] <diddledan> do you have boobies?
[19:44] <daftykins> not yet, as far as i can tell
[19:44] <diddledan> you need estrogen then
[19:46]  * daftykins spies Freenode lag
[19:46] <diddledan> Laggard!
[19:46]  * diddledan lags ‘ard
[19:46] <zmoylan-pi> i've had to kick irssi twice already.  ddos probably underway, my other irc server is grand
[19:46] <daftykins> so here's an amusing tale of modern technology, i decided to let my lovely new system update its' BIOS today - which it can do over the internet from inside the EFI!
[19:47] <zmoylan-pi> that sounds... fun
[19:47] <diddledan> scary
[19:47] <daftykins> however once it was done, it wanted the same image file again to do another portion, apparently - but if i told it to check online again it simply told me that it was already current!
[19:47] <diddledan> my new board has 16MB of bios/efi thingy chip
[19:47] <diddledan> two chips of 128Mbit
[19:47] <zmoylan-pi> oh is this one of those it runs out of space for updates whoopsies?
[19:47] <daftykins> it also refused to read flash drives for whatever reason, so i had to whip the side panel off, throw the image on a SATA HDD and plug it in so it could see it again
[19:48] <daftykins> :D
[19:48] <ali1234> my new board has an SPI programming header... so it's impossible to brick it
[19:48] <diddledan> ali1234: nice
[19:48] <zmoylan-pi> like the titanic was unsinkable... :-P
[19:48] <penguin42> have you got the raw image and a spi programmer?
[19:48] <ali1234> i have an spi programmer
[19:49] <daftykins> asus ones tend to be so as well, because it can read in from a USB drive too afaiui
[19:49] <diddledan> I resurrected a board a while back through one of those headers
[19:49] <diddledan> was an MSI jobby
[19:50] <daftykins> maybe i should contact asus about that glaring ommission
[19:50] <daftykins> when it updates online i think it just holds the image in RAM, so you don't have it anymore for the second boot
[19:50] <zmoylan-pi> The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair. - douglas adams
[19:51] <daftykins> :D
[19:51] <daftykins> diddledan: is your current win10 build ~43xx ?
[19:51] <zmoylan-pi> those wise words have been a great comfort while fixing things that couldn't /break/
[19:51] <penguin42> I had 'fun' recovering a phone I bricked over new year; turns out qualcomm based phones have a very very low level fallback boot loader you can reimage from
[19:51] <daftykins> lower than button press types?
[19:52] <ali1234> normally they have a failsafe in mask rom
[19:52] <penguin42> daftykins: Yes
[19:52] <diddledan> 14383 I think
[19:52] <penguin42> for even after you screw the fastboot up
[19:52] <daftykins> there's a big qualcomm encryption patchload coming for Nexus phones this month
[19:53] <daftykins> diddledan: ah yeah, i heard that's practically final
[19:53] <daftykins> gone gold so my news tells me :O
[19:53] <diddledan> Yup. the watermark is gone
[19:53] <daftykins> BAM and the watermark is GONE!
[19:56] <m0nkey_> What's the current feeling on TeamViewer?
[20:06] <zmoylan-pi> do crickets recommend teamviewer? :-P
[20:14] <ali1234> tasbot time http://twitchls.com/gamesdonequick
[20:18] <daftykins> m0nkey_: strikes me as harmless to use, but i don't think i'd install it anywhere - just have people use the 'run only' functionality
[20:19] <daftykins> at least that's a thing on the Windows version
[20:23] <daftykins> haha tool assisted speedrun (TAS) of a mario game that's literally walking through memory right now;
[20:23] <daftykins> www.twitch.tv/gamesdonequick
[20:24] <m0nkey_> I need an always on remote control thing
[20:25] <daftykins> OS?
[20:25] <daftykins> how'd the RAID experiments go btw?
[20:28] <m0nkey_> Windows
[20:28] <m0nkey_> Gave up
[20:29] <daftykins> which edition of Windows? because RDP is there if it's Pro or up
[20:29] <m0nkey_> Eventually installed Proxmox, which does ZFS root.. allowing me to put a SSD cache, so it's fast.
[20:29] <daftykins> ah har
[20:36] <daftykins> so i'd just run regedit and modify the default RDP port listened on and forward it, then job done
[20:42] <m0nkey_> <-- home edition, there is no rdp server
[20:44] <daftykins> which version? you can hack it on i always heard
[20:53] <m0nkey_> 10
[20:54] <daftykins> hrmm.
[20:55] <daftykins> https://github.com/stascorp/rdpwrap/releases
[20:55] <daftykins> apparently this adds it :D
[21:17] <m0nkey_> tried it, doesn't work.. the listener service fails to start
[21:50] <daftykins> hmm
[21:51] <daftykins> well you can teamviewer it if you enable 2FA and use a good pass i suspect
[22:01] <m0nkey_> thats new
[22:02] <m0nkey_> TV has introduced trusted devices
[22:02] <zmoylan-pi> didn't they have a slight security problem recently?
[22:04] <m0nkey_> Hmm, also Chrome Remote Desktop.. that could work
[22:09] <m0nkey_> Yeah, that works well :-)
[22:49] <daftykins> err
[22:49] <daftykins> remote tech in a browser? seems legit (not)
[22:50] <ali1234> zmoylan-pi: teamviewer breach seems to be down to the linked-in hack
[22:50] <ali1234> no evidence that they were directly compromised (would have been much bigger news if they were)
[22:50] <daftykins> yeah just poor passwords
[22:50] <daftykins> and pass reuse
[22:51] <ali1234> i still wouldn't use it though
[22:51] <ali1234> ssh is enough
[22:51] <daftykins> we were talking about windows remote access, so no
[22:52] <ali1234> put windows in a VM on a linux host
[23:00] <daftykins> that's ridiculous
[23:07] <zmoylan-pi> can you run windows in a vm under os/2? :-P
[23:08]  * penguin42 isn't aware of a VM system for os/2
[23:11] <zmoylan-pi> there was news of a new release of os/2 and i have seen notes about installing it in a vm... just seems odd that no crazy sod has made windows run under os/2... :-)
[23:12] <SebthreeBQM10HD> 1 2 3
[23:12] <penguin42> a b c ?
[23:12] <SebthreeBQM10HD> d e f g
[23:13] <SebthreeBQM10HD> h i j k l m n o p q r s t u v w x y z
[23:15] <Myrtti> eh
[23:15] <daftykins> i've a feeling it's a demonstration of how irritating someone can be :)
[23:18] <SebthreeBQM10HD> daftykins, no it was a response to penguin42
[23:20] <daftykins> you fooled me :D
[23:34] <SebthreeBQM10HD> daftykins, oh and irritating would have been flooding the channel with the alaphbet a few or more liens
[23:35] <daftykins> oh you wouldn't have lasted long :)
