[06:17] <chesedo> morning all
[06:19] <paddatrapper> Morning chesedo, everyone 
[06:22] <chesedo> hi paddatrapper
[06:22] <andrewlsd_> Morning chesedo, paddatrapper
[06:23] <andrewlsd_> Morning theblazehen Kilos Squirm squish102 plustwo nuvolari_ Mzolisto ludo
[06:23] <andrewlsd_> Mzolisto: Quassel for the win :-)
[06:39] <chesedo> hi andrewlsd
[06:44] <theblazehen> hey andrewlsd, all
[06:45] <Kilos> hi chesedo andrewlsd paddatrapper theblazehen inetpro and the lurking types
[06:45] <theblazehen> hey Kilos
[06:45] <Kilos> hi roabish 
[06:46] <Kilos> even you belgium peeps have been brainwashed by the yanks theblazehen 
[06:46] <Kilos> with this hey instead of hi
[06:46] <theblazehen> hehe
[06:46] <Kilos> too many movies
[06:46] <chesedo> hi theblazehen Kilos
[06:47] <theblazehen> hi chesedo
[06:47] <theblazehen> Kilos heh, not enough movies... Haven't seen in like 10 months
[06:56] <nsnzero> morning all 
[06:57] <theblazehen> hey nsnzero
[06:59] <Squirm_> Morning
[06:59] <theblazehen> Hi Squirm_
[07:02] <nsnzero> hi theblazehen and Squirm_ 
[07:16] <Kilos> hi nsnzero 
[07:17] <nsnzero> hi Kilos 
[07:43] <chesedo> ho nsnzero Squirm_
[07:43] <chesedo> s/ho/hi/
[07:43] <Kilos> lol
[07:43] <Kilos> hi ho hi ho its off to work we go
[08:42] <chesedo> that sounds like someone who has just come from the pub
[08:51] <Kilos> lol
[09:23] <magespawn> good morning
[09:35] <chesedo> morning magespawn
[10:05] <antonmay> Good day all
[10:06] <Kilos> hi antonmay 
[10:06] <Kilos> antonmay what
[10:06] <Kilos> antonmay or may not, all depends
[10:07]  * Kilos hides
[10:07] <antonmay> lol
[10:07] <antonmay> ja
[10:07] <Kilos> all good?
[10:08] <antonmay> No not really, I need help, well somebody that can get me a DAS server that can take 10TB SATA drives
[10:09] <theblazehen> antonmay I assume you can't build it yourself?
[10:10] <antonmay> I need one with 12 bays I need 60TB
[10:11] <antonmay> I have a md3200 but can only go 8TB drives and SAS only
[10:11] <theblazehen> Is something like ceph not an option? Or glusterfs?
[10:11] <theblazehen> Then you can use say 2 nodes
[10:11] <theblazehen> SAS can take sata drives IIRC, but sata can't take sas
[10:11] <antonmay> I have glusterfs running, but this is to connect to one of our mysql servers
[10:45] <ludo> afternoon andrewlsd
[10:46] <Kilos> hi ludo 
[10:46] <andrewlsd> \o ludo
[10:46] <ludo> Hi Kilos
[10:46] <Kilos> hi thatgraemeguy 
[10:46] <Kilos> and inetpro 
[10:46] <ludo> Hi All!
[10:47] <andrewlsd> antonmay: 45Drives.com (basically supermicro devices) as designed/used by BackBlaze.com
[10:48] <andrewlsd> antonmay: I might have missed something, am I correct that this is not for glusterfs, but _is_ for storage for mysql servers. in which case, iops really matters.
[10:53] <antonmay> yes andrew
[10:54] <antonmay> i got the seagate 10TB ironwolf disks, but sata not sas
[11:03] <andrewlsd> ie, you'll need lots of SATA backplanes.
[11:04] <andrewlsd> antonmay: but watch out. Several of the multi-SATA-port backplanes share a single SATA throughput channel, so if a 2-port, it effectively becomes 0.5 speed.
[11:05] <andrewlsd> something like these might be useful. I am not recommending them, just googled and this was first result https://www.startech.com/Cards-Adapters/HDD-Controllers/SATA-Cards/4-Port-PCI-Express-SATA-6Gbps-RAID-Controller-Card~PEXSAT34RH
[11:05] <theblazehen> If it's a shared 6 gbit sata, then I'm guessing most HDDs can't even push 3 gbit
[11:05] <theblazehen> (Even my raid + ssd can't push more than 3.5 gbit total)
[11:06] <andrewlsd> so, PCIE SATA cards are probably fine, just be careful of "port multiplier" cards
[11:08] <andrewlsd> multipliers also do speed negotiation apparently, port will function at speed of lowest SATA-version/speed drive attached  (much like USB hub)
[11:10] <andrewlsd> antonmay: remember if building raid arrays on these, to spread the raid members across multiple hardware controllers, otherwise a single hardware controller card failure would take out your whole drive array.  
[11:10] <andrewlsd> although, tbh, that's a bit like saying losing a single motherboard would take out your whole server.
[11:11] <andrewlsd> so suggest you disregard my previous "spread" comment.
[11:12] <nsnzero> andrewlsd: hi 
[11:12] <nsnzero> doesnt raid have a protocol for single hdd failure ?
[11:14] <theblazehen> nsnzero RAID 5, yeah. RAID 6 is 2 disk
[11:16] <nsnzero> good to know theblazehen 
[11:17] <theblazehen> nsnzero and an arbitary number if you use erasure coding
[11:23] <andrewlsd> \o nsnzero
[11:24] <andrewlsd> nsnzero: single hdd failure. but not hdd controller (of several drives) failure. 
[11:24] <andrewlsd> my point was to convey that using a RAID level that can tolerate drive failure might _not_ be enough if an add-on card fails.
[11:25] <nsnzero> 100% correct andrewlsd 
[11:25] <andrewlsd> if creating multiple raid arrays, then the drives could be selected one from each controller. to minimize that risk.
[11:26] <andrewlsd> but not if a single array is being created.
[11:26] <nsnzero> card failures are much rarer than hdd failures though 
[11:26]  * andrewlsd drinks yoghurt 
[11:26] <andrewlsd> ^ random
[11:27]  * andrewlsd woke up at 2am trying to figure out how to test hyper-converged oVirt configuration.
[11:27] <andrewlsd> theblazehen: I need hardware too :-/
[11:28] <andrewlsd> something like 3 hosts with internal drives providing glusterfs shares.
[11:28]  * andrewlsd does not want to do nested KVM to make that lab.
[11:28] <nsnzero> orvirt is a vm - hyper-converged - no idea about that 
[11:29] <theblazehen> Yeah. How does it handle a node going down (planned)? @andrewlsd 
[11:29] <andrewlsd> theblazehen: glusterfs heals.
[11:29] <andrewlsd> (and/or re-balances)
[11:29] <theblazehen> andrewlsd But what if I don't want it to heal. I want it to wait for me to bring the node back up
[11:29] <andrewlsd> but those are some of the questions I'm trying to get answers for.
[11:29] <theblazehen> Is that possible?
[11:30] <andrewlsd> I doesn't _node_ the answer ;-D
[11:30] <theblazehen> ha ha
[11:30]  * nsnzero knows what hyper-converged is now 
[11:31] <andrewlsd> hmm. virtual Datacentre should come with Oculus Rift interface.
[11:31] <andrewlsd> B: "I have a single-node hyperconverged platform"
[11:31] <andrewlsd> C: "Oh, you mean you have a server, with disks, memory and network cards"
[11:32] <andrewlsd> B:  ;-(
[11:32]  * andrewlsd imagines that as an XKCD cartoon.
[11:33] <theblazehen> Javascript sucks. Well, nodejs. Spent around 3 hours so far trying to get gulp / babel to build things. Or whatever. 
[11:40] <nsnzero> andrewlsd: lol
[11:40] <nsnzero> its much more costly as you have to upgrade the hardware at once 
[11:48] <nsnzero> my further venture in filesystems and disk hardware involves formating a hdd with luks and btrfs 
[11:53] <theblazehen> You've got local backups then right? I use btrfs, but I don't trust it after last time
[11:57] <nsnzero> theblazehen: just testing it out - first time i got luks to work properly
[12:23]  * andrewlsd sings: You're up all night to get luk-key
[12:30] <nsnzero> andrewlsd: thats funny -lol
[12:35] <nsnzero> have a good afternoon everyone
[12:38] <antonmay> What is so difficult to understand the concept of sftp???? AAARRRGGGGG
[12:39] <antonmay> PS welcome back Kilos. All good?
[12:49] <andrewlsd> antonmay: because people think it is ftps.
[13:01] <thatgraemeguy> good morning
[13:02] <thatgraemeguy> better late than never :)
[13:06]  * andrewlsd disconnects
[13:24] <Kilos> yeah all ok but massive storm starting here. could be gone a while
[17:27] <Kilos-> storm has hit and power went. night all, sleep tight
[17:27] <inetpro> same here... good night kil... 
[17:34] <nsnzero> good evening all
[19:19] <magespawn> chat later all
[19:53] <SilverCode> andrewlsd: Virtual Datacenter + Occulas Rift = Hackers (movie)
[23:02] <superfly> SilverCode: Brilliant!
