| sneezewort | Is there a way to see the changes that are made to my system in regards to networking when I run "apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty"? | 16:30 |
| bekks | sneezewort: That will install a new kernel. | 16:31 |
| sneezewort | Right. But can I see the changes in the kernel in regards to networking? | 16:31 |
| teward | sneezewort: you might want to look at the changelogs for the packages those install | 16:32 |
| bekks | sneezewort: You'd have to investigate the kernel changelog then. But whats the actual issue behind your questions? | 16:32 |
| rberg_ | sneezewort: for the high level you could look at kernel newbies changelog digest, for the details look at the changelogs on kernel.org.. | 16:34 |
| sneezewort | I posted in here last week. I am on a University campus. Using VMWare ESXi when I install Ubuntu 12.04 I can download large files no problem. When upgrade with the above command and change nothing else, large files stall and become very slow. | 16:35 |
| sneezewort | On campus network is still fast. | 16:35 |
| sneezewort | I am trying to figure out what is happening so I can ask campus networks to help. | 16:36 |
| pmatulis | sneezewort: what command? | 16:36 |
| sneezewort | "apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty" | 16:36 |
| sneezewort | Or do-release-upgrade. basically anything greater than the initial install of 12.04. | 16:37 |
| pmatulis | sneezewort: what mirror are you using? | 16:48 |
| sneezewort | http://us.archive.ubuntu.com/ubuntu/ | 16:48 |
| pmatulis | sneezewort: see if esx can emulate a different network adapter | 16:49 |
| sneezewort | It can I have tried all 3. No dice. I have tried several different versions of VMWare tools. Thats what make this so hard to track down. It is a combination of VMWare Ubuntu and my campus network that is the problem. I am just trying to get a grasp on what is happening. | 16:53 |

| smoser | arges, http://paste.ubuntu.com/10374983/ | 17:34 |
| smoser | is that related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1329434 | 17:34 |
| smoser | $ uname -r | 17:34 |
| smoser | 3.13.0-43-generic | 17:34 |
| smoser | ie, see it in a guest running that kernel, but no way o fkonwing what the host is running. | 17:34 |
| smoser | this is on digital ocean | 17:34 |
| smoser | does the host have to possibly update their kernel ? | 17:36 |
| === codex__ is now known as codex | ||
| smoser | smb, so above.. woudlthe host kernel have to have been updated also ? | 17:57 |
| smb | smoser, I remember it only vaguely but if its the same issue then it might require an update on the host (if that is 3.13 based) | 17:58 |
| smoser | cool. thanks. | 17:58 |
| sneezewort | Just FYI gang, I tried the newest Debain using 3.2.0-4-amd64 kernel and the problem does not occur. | 18:07 |
| pmatulis | sneezewort: would be good to know if issue was observed with Ubuntu 14.04 | 18:15 |
| === Lcawte|Away is now known as Lcawte | ||
| sneezewort | pmatulis, yep fresh install of 14.04, same behavior. | 18:47 |
| pmatulis | sneezewort: does vmware web site show 12.04 and 14.04 as supported for your version of esx? | 18:48 |
| sarnold | sneezewort: is your campus doing any goofy transparent proxy things to your network traffic? | 18:49 |
| pmatulis | http://www.vmware.com/resources/compatibility/search.php?action=base&deviceCategory=software <= sneezewort | 18:49 |
| sarnold | (Ubuntu is pages 5-... under "Canonical", heh) | 18:51 |
| sneezewort | sarnold, probably. I only have control of the network in our server room. Outside of that I have no idea. | 18:51 |
| sneezewort | pmatulis, It looks like 14.04 is not supported, but 12.04 is. | 18:52 |
| anubhav | Hi, I had some question regarding deployment and if ubuntuserver + openstack fits my needs, is someone familiar with all this? | 19:06 |
| sarnold | anubhav: welcome; irc tends to work best if you can ask specific questions.. | 19:29 |
| SchrodingersScat | !ask | 19:30 |
| ubottu | Please don't ask to ask a question, simply ask the question (all on ONE line and in the channel, so that others can read and follow it easily). If anyone knows the answer they will most likely reply. :-) See also !patience | 19:30 |
| anubhav | okay thanks... here is my question.... I have a few systems(4-5) in my institute and that have 16cpu and 32gb ram each, we are planning to organize the architecture to be used as a super computer and i am looking into the open source solutions. Rocs cluster is one option but i think ubuntu cloud would be better. So how does it work. Will using IaaS allow better queuing technique? By this i mean that in rocks cluster, you submit a job and it schedu | 19:44 |
| anubhav | les it to one of the compute node. Instead can the cloud check on the fly how many resources are available and use them effectively? | 19:44 |
| anubhav | So will it essentially become a single system with (4*16) cores and 4*32 gb ram? | 19:45 |
| anubhav | Also i guess adding new nodes will be easier in such a system | 19:45 |

| sarnold | anubhav: you'll have to figure out how you really want to use your cluster; if you want to use it like AWS, where it's cheap and easy to make virtual machines for individual users, then openstack is a fine approach | 19:52 |
| sarnold | anubhav: if you want to run large, involved simulations that require the combined resources of all the machines to complete, that requires a different kind of option, something more like beowulf or gridengine or torque or similar.. | 19:53 |
| anubhav | sarnold, mostly it is going to be used for academic purpose only, running simulations etc. So will it incur a performance hit if I use openstack | 19:53 |
| sarnold | anubhav: openstack involves virtualization, which tends to introduce some overhead; how much overhead depends upon workload, etc., you'd have to measure it to see if you care.. | 19:54 |
| anubhav | okay, the reason i am considering this is because if i have it virtualized, then I can allocate a smaller instance as well to someone who needs only decent power. There can be one large instance reserved for simulations and other tasks to be run | 19:59 |
| anubhav | is the performance difference between a beowulf cluster and a virtualized cluster with same specs significant, assuming that at a given moment only a few users are online and submitting jobs | 20:01 |
| sarnold | anubhav: you'd probably be writing custom code to use the features of a beowulf cluster; is your team writing MPI-based calculations? that might help.. | 20:06 |
| === martinst is now known as martins-afk | ||
| anubhav | sarnold, not my team. but there is another and they are using libraries that i am pretty sure have good mpi implementation | 20:07 |
| anubhav | sarnold, I am involved in managing the cluster and figuring out which might be the best path | 20:08 |
| === martins-afk is now known as martinst | ||
| sarnold | anubhav: then you might want something more like beowulf rather than openstack. of course, if you've got mixed loads, openstack might still be useful, you could probably build a beowulf out of virtualized systems... but .. I'm scared to suggest it. :) | 20:09 |
| anubhav | sarnold, I understand. I was also sceptical is virtualizing would be a good thing | 20:09 |
| sarnold | anubhav :) | 20:10 |
| anubhav | sarnold, thanks for the suggestions. I will look deeper into beowulf | 20:10 |
| sarnold | anubhav: have fun :) | 20:12 |
| nch | hello can someone help me with, grub, mdadm (raid 5 with 8x2tb) and a boot error: "device with uuid not found"? | 20:24 |
| Prezident | did you try boot grub without uid ? | 20:25 |
| nch | how can I do that? | 20:25 |
| Prezident | In your grub file | 20:26 |
| Prezident | GRUB_DISABLE_LINUX_UUID=true | 20:26 |
| Prezident | Have you installed/loaded kernel to /boot? | 20:26 |
| Prezident | This is three errors i see, this is for the boot error. | 20:27 |
| nch | yep all worked well put I reconneted some harddrives to other sata ports and then I got this error | 20:28 |
| nch | you sure that I can disable the uuids, because all drives in the grub config file are defined by uuids | 20:28 |
| Prezident | Aha, so this happend after you installed some drives? | 20:29 |
| nch | no the drives are all the same as before I only changed some cables and I think I reconnected some drives to other sata ports | 20:30 |
| Prezident | Aha, bios can see them all? | 20:30 |
| nch | I read that the uuids wont affect the raid because the raid information is stored directly on the drives, am I right? | 20:30 |
| nch | yes all drives are available in bios | 20:30 |
| nch | http://sourceforge.net/projects/boot-repair-cd/ | 20:32 |
| nch | is this compatible with raid and gpt? | 20:33 |
| nch | well boot repair tells me to create a partition with the bios_grub flag, but one of my drives have it -.- | 20:48 |
