[00:05] ;] [00:58] this mdadm array is kicking my ass still [00:59] fastest speed i've seen is 5MB/sec [00:59] i'm doing random writes [00:59] :( [00:59] how'd mounting it from a live session of 7 work out? [00:59] it's now on ubuntu 16.04 [01:00] no difference in speed between centos or ubuntu [01:01] what block size? [01:04] 512 [01:05] 2000398934016 bytes / 1953383488 blocks (md0) / 2 = 512 [01:05] hmm bit large [01:05] thats bytes, not K [01:06] ah [01:06] if they were advanced format disks, that'd be screwing you up [01:06] both my hw_sector_size and physical_block_size is 512 [01:06] some can mask that though [01:15] re-formated the filesystem, forcing 4K, i've seen a slight increase in writes, from 4MB/sec to 6MB/sec [01:15] Any way to force 4K sectors in mdadm? [01:16] i forget, is it a host or a KVM guest? [01:16] KVM host [01:16] hmm well without any running the virt tech should be irrelevant [01:17] doing a simple DD [01:17] Hitting 20MB/sec [01:17] KVM tops out around 6 [01:18] 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 52.3285 s, 20.5 MB/s [01:22] How'd I force it to build using 4K? [01:22] you are using a blocksize though right? on the dd command [01:24] no idea there, when i've done RAID it's been for large files so i've done 64KB or larger [01:50] i've destroyed the array and testing with a single disk [01:50] see how kvm performs on writes with that [01:51] interesting [01:51] with a single disk, it's slow [01:52] testing the second disk [01:55] o0 [01:55] wow, even with the second disk, it's super slow writes [01:56] maybe it's my controller :) [01:56] what is it? [01:56] maybe there's a bad driver, mmm [01:58] whats the command to see that again? [01:58] lspci ? [01:58] 00:11.0 SATA controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [AHCI mode] (rev 40) [01:59] hmm so it is just chipset based most likely [01:59] i thought this was like, a workplace server [01:59] heh, no [01:59] just some home crap box [01:59] ah [02:00] Ubuntu doesn't do ZFS as a root filesystem, right? [02:00] can you ID the motherboard? maybe that'd give some search results [02:00] mmm, pass [02:00] Base Board Information [02:00] Manufacturer: MSI [02:00] Product Name: 870A-G54 (MS-7599) [02:00] sounds right for how it used to be, but no idea on current [02:00] it's an old AMD board [02:01] AMD® 870+SB850 chipset [02:01] mmk [02:01] Yeah, wasn't a brilliant board to begin with :) [02:02] can you check out what SATA configuration modes you have in BIOS? [02:02] From memory, ACHI, IDE and RAID [02:03] mmm, apparently AHCI is really bad on that chipset [02:03] oh [02:03] okay [02:03] i see talk of folk moaning about AMD's AHCI support [02:03] I'll try that soon [02:03] Got to put my two girls to bed [02:03] brb [02:03] it's a total longshot but yeah, maybe in IDE mode it'll do something different :D [02:03] roger that [02:18] ok they're in bed [02:20] and i'm in IDE mode [02:20] dun-dun-duuuuun [02:20] kicking off a vm install [02:21] ok, write speeds are up [02:21] avg 10MB/sec [02:21] :/ [02:21] that's a slight improvement [02:21] better than 4MB/sec [02:22] is that install just the quivalent of a debootstrap kinda process on this RAID 1, then? [02:22] *equiv [02:22] yes, i guess so [02:22] i'm booting the debian install iso [02:22] and when it starts the install it slows to a crawl [02:24] 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] probably be moot due to not having the same chipset though [02:25] it's probably because of crappy chipset and drives [02:25] when I do a ZFS rootfs, I can add a SSD as a write cache, so it's fast that way. [02:26] i saw something about using a cache drive with mdadm too whilst trawling around [02:27] i've not used mdadm before so it could be fun anyways :) [02:27] ok gotta sleep for now, ttfn \o [05:40] urgh time of yr its hard to sleep..hot and sticky ;[ [05:50] whats the temp there? [05:54] 24c [05:54] 66% humidity [05:55] that it? :) [06:00] heh [06:00] I was expecting 32C+ :) [06:00] feels sticky and cant have my window open as building new flats nex door [06:00] so its hot ;[ [06:04] it's 19C, feels like 24C here this evening. 83% humidity. [06:04] It's actually been a cool day [06:04] Most of the week it reached 31C [09:22] morning boys and girls. [10:55] wow. I missed the whole dallas thing on thursday [10:55] apparently the police used a robot to end the violence in a "show of lethal force" (as someone wrote) [10:57] 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] because they didn't have the area secure? [11:06] in next hostage situation, a drone, police, media or private will escalate things after this [11:11] even worse, you'll probably start hearing of more paranoid individuals shooting down drones as they think the police are out to get them === brmbrmca1 is now known as brmbrmcar === brmbrmca1 is now known as brmbrmcar === pavlushka_ is now known as pavlushka [19:22] wtf? this is twisted: https://youtu.be/sg0D1PpgCXs [19:23] transformers go "politically correct” with optimus turning female [19:23] bit of swearing and shooting each other [19:38] that's... weird [19:39] also, double clicking desktop icons kills kittens [19:39] thats default in winme [19:41] hmm actually i had a massive mental fail there, that IS default :D [19:42] it's the active desktop shenanigans... i spent a large amount of time turning that off in every pc i encountered [19:42] I always knew you were a nutjob [19:43] just me and my collection of singing potatoes [19:43] zmoylan-pi: because who wouldn’t want html everywhere?! [19:43] yeah, i couldn't stand that rubbish [19:43] seems i'm as confused as megatron today [19:43] do you have boobies? [19:44] not yet, as far as i can tell [19:44] you need estrogen then [19:46] * daftykins spies Freenode lag [19:46] Laggard! [19:46] * diddledan lags ‘ard [19:46] i've had to kick irssi twice already. ddos probably underway, my other irc server is grand [19:46] 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] that sounds... fun [19:47] scary [19:47] 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] my new board has 16MB of bios/efi thingy chip [19:47] two chips of 128Mbit [19:47] oh is this one of those it runs out of space for updates whoopsies? [19:47] 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] :D [19:48] my new board has an SPI programming header... so it's impossible to brick it [19:48] ali1234: nice [19:48] like the titanic was unsinkable... :-P [19:48] have you got the raw image and a spi programmer? [19:48] i have an spi programmer [19:49] asus ones tend to be so as well, because it can read in from a USB drive too afaiui [19:49] I resurrected a board a while back through one of those headers [19:49] was an MSI jobby [19:50] maybe i should contact asus about that glaring ommission [19:50] 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] 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] :D [19:51] diddledan: is your current win10 build ~43xx ? [19:51] those wise words have been a great comfort while fixing things that couldn't /break/ [19:51] 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] lower than button press types? [19:52] normally they have a failsafe in mask rom [19:52] daftykins: Yes [19:52] 14383 I think [19:52] for even after you screw the fastboot up [19:52] there's a big qualcomm encryption patchload coming for Nexus phones this month [19:53] diddledan: ah yeah, i heard that's practically final [19:53] gone gold so my news tells me :O [19:53] Yup. the watermark is gone [19:53] BAM and the watermark is GONE! [19:56] What's the current feeling on TeamViewer? [20:06] do crickets recommend teamviewer? :-P [20:14] tasbot time http://twitchls.com/gamesdonequick [20:18] 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] at least that's a thing on the Windows version [20:23] haha tool assisted speedrun (TAS) of a mario game that's literally walking through memory right now; [20:23] www.twitch.tv/gamesdonequick [20:24] I need an always on remote control thing [20:25] OS? [20:25] how'd the RAID experiments go btw? [20:28] Windows [20:28] Gave up [20:29] which edition of Windows? because RDP is there if it's Pro or up [20:29] Eventually installed Proxmox, which does ZFS root.. allowing me to put a SSD cache, so it's fast. [20:29] ah har [20:36] so i'd just run regedit and modify the default RDP port listened on and forward it, then job done [20:42] <-- home edition, there is no rdp server [20:44] which version? you can hack it on i always heard [20:53] 10 [20:54] hrmm. [20:55] https://github.com/stascorp/rdpwrap/releases [20:55] apparently this adds it :D [21:17] tried it, doesn't work.. the listener service fails to start [21:50] hmm [21:51] well you can teamviewer it if you enable 2FA and use a good pass i suspect [22:01] thats new [22:02] TV has introduced trusted devices [22:02] didn't they have a slight security problem recently? [22:04] Hmm, also Chrome Remote Desktop.. that could work [22:09] Yeah, that works well :-) [22:49] err [22:49] remote tech in a browser? seems legit (not) [22:50] zmoylan-pi: teamviewer breach seems to be down to the linked-in hack [22:50] no evidence that they were directly compromised (would have been much bigger news if they were) [22:50] yeah just poor passwords [22:50] and pass reuse [22:51] i still wouldn't use it though [22:51] ssh is enough [22:51] we were talking about windows remote access, so no [22:52] put windows in a VM on a linux host [23:00] that's ridiculous [23:07] 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] 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] 1 2 3 [23:12] a b c ? [23:12] d e f g [23:13] h i j k l m n o p q r s t u v w x y z [23:15] eh [23:15] i've a feeling it's a demonstration of how irritating someone can be :) [23:18] daftykins, no it was a response to penguin42 [23:20] you fooled me :D [23:34] daftykins, oh and irritating would have been flooding the channel with the alaphbet a few or more liens [23:35] oh you wouldn't have lasted long :)
