| chesedo | hi andrewlsd | 06:39 |
| theblazehen | hey andrewlsd, all | 06:44 |
| Kilos | hi chesedo andrewlsd paddatrapper theblazehen inetpro and the lurking types | 06:45 |
| theblazehen | hey Kilos | 06:45 |
| Kilos | hi roabish | 06:45 |
| 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 | 06:46 |
| theblazehen | hi chesedo | 06:47 |
| theblazehen | Kilos heh, not enough movies... Haven't seen in like 10 months | 06:47 |

| antonmay | Good day all | 10:05 |
| Kilos | hi antonmay | 10:06 |
| Kilos | antonmay what | 10:06 |
| Kilos | antonmay or may not, all depends | 10:06 |
| * Kilos hides | 10:07 | |
| antonmay | lol | 10:07 |
| antonmay | ja | 10:07 |
| Kilos | all good? | 10:07 |
| antonmay | No not really, I need help, well somebody that can get me a DAS server that can take 10TB SATA drives | 10:08 |
| theblazehen | antonmay I assume you can't build it yourself? | 10:09 |
| antonmay | I need one with 12 bays I need 60TB | 10:10 |
| 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 | 10:11 |
| ludo | afternoon andrewlsd | 10:45 |
| 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! | 10:46 |
| andrewlsd | antonmay: 45Drives.com (basically supermicro devices) as designed/used by BackBlaze.com | 10:47 |
| 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. | 10:48 |
| antonmay | yes andrew | 10:53 |
| antonmay | i got the seagate 10TB ironwolf disks, but sata not sas | 10:54 |
| andrewlsd | ie, you'll need lots of SATA backplanes. | 11:03 |
| 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. | 11:04 |
| 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) | 11:05 |
| andrewlsd | so, PCIE SATA cards are probably fine, just be careful of "port multiplier" cards | 11:06 |
| andrewlsd | multipliers also do speed negotiation apparently, port will function at speed of lowest SATA-version/speed drive attached (much like USB hub) | 11:08 |
| 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. | 11:10 |
| andrewlsd | so suggest you disregard my previous "spread" comment. | 11:11 |
| nsnzero | andrewlsd: hi | 11:12 |
| nsnzero | doesnt raid have a protocol for single hdd failure ? | 11:12 |
| theblazehen | nsnzero RAID 5, yeah. RAID 6 is 2 disk | 11:14 |
| nsnzero | good to know theblazehen | 11:16 |
| theblazehen | nsnzero and an arbitary number if you use erasure coding | 11:17 |
| andrewlsd | \o nsnzero | 11:23 |
| 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. | 11:24 |
| 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. | 11:25 |
| 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 | 11:26 |
| * andrewlsd woke up at 2am trying to figure out how to test hyper-converged oVirt configuration. | 11:27 | |
| andrewlsd | theblazehen: I need hardware too :-/ | 11:27 |
| 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 | 11:28 |
| 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? | 11:29 |
| andrewlsd | I doesn't _node_ the answer ;-D | 11:30 |
| theblazehen | ha ha | 11:30 |
| * nsnzero knows what hyper-converged is now | 11:30 | |
| 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" | 11:31 |
| andrewlsd | B: ;-( | 11:32 |
| * andrewlsd imagines that as an XKCD cartoon. | 11:32 | |
| theblazehen | Javascript sucks. Well, nodejs. Spent around 3 hours so far trying to get gulp / babel to build things. Or whatever. | 11:33 |
| nsnzero | andrewlsd: lol | 11:40 |
| nsnzero | its much more costly as you have to upgrade the hardware at once | 11:40 |
| nsnzero | my further venture in filesystems and disk hardware involves formating a hdd with luks and btrfs | 11:48 |
| theblazehen | You've got local backups then right? I use btrfs, but I don't trust it after last time | 11:53 |
| nsnzero | theblazehen: just testing it out - first time i got luks to work properly | 11:57 |
| * andrewlsd sings: You're up all night to get luk-key | 12:23 | |
| nsnzero | andrewlsd: thats funny -lol | 12:30 |
| nsnzero | have a good afternoon everyone | 12:35 |
| antonmay | What is so difficult to understand the concept of sftp???? AAARRRGGGGG | 12:38 |
| antonmay | PS welcome back Kilos. All good? | 12:39 |
| andrewlsd | antonmay: because people think it is ftps. | 12:49 |
| thatgraemeguy | good morning | 13:01 |
| thatgraemeguy | better late than never :) | 13:02 |
| * andrewlsd disconnects | 13:06 | |
| Kilos | yeah all ok but massive storm starting here. could be gone a while | 13:24 |
| Kilos- | storm has hit and power went. night all, sleep tight | 17:27 |
| inetpro | same here... good night kil... | 17:27 |
| nsnzero | good evening all | 17:34 |
| magespawn | chat later all | 19:19 |
