| infinity | IRCsloth: Still around? | 05:28 |
|---|---|---|
| infinity | IRCsloth: Can you try a dapper liveCD on that machine to see if it creates the device correctly? | 05:29 |
| IRCsloth | yeah, I'm here, just not looking at the screen | 05:39 |
| IRCsloth | I'll try a dapper live cd to see. Fedora core4 wasn't creating the devices for me either so I have a feeling it's a generic udev problem | 05:40 |
| IRCsloth | RedHat 9 however works like a charm, heh. | 05:40 |
| infinity | IRCsloth: I just talked to our udev guy who showed me the code in question. We dfinitelty SHOULD be creating tape devices. | 06:05 |
| neuralis | infinity: did you ever find anything out about the certification exams? | 06:10 |
| infinity | Nothing meaninful or interesting, no. | 06:18 |
| nictuku | considering your experience, what would be an acceptable maximum usage for a network wide updates server, written in python, in mb? | 06:18 |
| nictuku | nwu, in this case | 06:18 |
| nictuku | maximum memory usage, I mean | 06:19 |
| nictuku | like, 10M, 15, 30, 100? | 06:19 |
| neuralis | what memory-intensive operation(s) are you performing? | 06:19 |
| neuralis | are you caching something? package lists? | 06:20 |
| nictuku | neuralis, getting relatively big list of packages and storing in a database. only temporary sqlobjects cache (should end after the thread is closed) | 06:20 |
| neuralis | so how would you eat up a hundred megs of memory? | 06:20 |
| nictuku | I mean, not in a developers POV, but in a sysadmin pov. | 06:21 |
| neuralis | i understand what you're asking, but i'm not sure why you're asking it. why do you think something like nwu will end up chewing up a lot of ram? | 06:21 |
| nictuku | what would a an admin expect for that? I'm an admin and I don't like how much memory it's using currently, like 24mb | 06:21 |
| nictuku | neuralis, because it's currently buggy | 06:21 |
| neuralis | 24mb isn't problematic at all, but it would be nice to cut it down eventually if there's no need for it. | 06:22 |
| nictuku | I'm fixing that, but although it won't ever use less than 10mb (python VM and all classes loaded), I wonder what would a sane target value for that. | 06:22 |
| neuralis | remove obvious leaks and memory holes, and then simply don't worry about it. | 06:23 |
| nictuku | neuralis, last week the memory usage was growing with no limit, until linux oom killer kills the process hehe | 06:23 |
| neuralis | yeah, leaks are bad, m'kay. | 06:23 |
| nictuku | ok, I think I'm getting paranoic about that | 06:23 |
| neuralis | no need. | 06:24 |
| infinity | As neuralis said, just make sure it doesn't leak. | 06:24 |
| infinity | Maybe try to make certain bits more efficient, if they're obviously not. | 06:24 |
| infinity | No one expects a python application to be "slim", however. | 06:24 |
| ajmitch | I'd never call apt-proxy lightweight, for example | 06:26 |
| nictuku | that could be a good base of comparision, btw | 06:27 |
| nictuku | it's using 50mb of memory in a server at work, and it's just sitting there. | 06:28 |
| nictuku | nwu is fine then :-) | 06:28 |
| neuralis | nictuku: hoare had something to say about premature optimization... kill leaks and focus on more worthwhile things like security and stability; memory use can be optimized later. | 06:28 |
| === fabbione [i=fabbione@gordian.fabbione.net] has joined #ubuntu-server | ||
| nictuku | it took me a month to spot and stop the leak. i'm hoping that won't happen often after this painful learning | 06:32 |
| nictuku | but it was fun :-) | 06:32 |
| ajmitch | hi fabbione | 06:32 |
| fabbione | morning | 06:32 |
| nictuku | nwu big inserts: mysql=0m12.316s, sqlite=0m49.179s. some of these in a row (although really unlikely to happen) would kill a small server IO sub-system | 06:46 |
| neuralis | er. what are these inserts doing? | 06:46 |
| nictuku | iostat shows a big write queue and usage | 06:47 |
| nictuku | neuralis, initial machine setup. basically packages versions and repository data | 06:48 |
| nictuku | oh. transactions off | 06:49 |
| neuralis | ok, well, it's more than likely that you're using a suboptimal schema. | 06:49 |
| === nandemonai [n=nandemon@ppp140-154.lns2.adl2.internode.on.net] has joined #ubuntu-server | ||
| nictuku | I wouldn't expect a good result now that I remember it's not using transactions. | 06:50 |

| \sh | fabbione: actual ubunt--server amd64 daily is broken, right? | 10:36 |
| fabbione | \sh: dunno.. i am not on server for this release | 10:37 |
| \sh | well...looks like it...no di kernel modules nothing...trying flight 6 now...debian amd64 port is far from being usable...so I need a running amd64 debian distro... | 10:39 |
| === rouven [n=rouven@p54BF3FB4.dip0.t-ipconnect.de] has joined #ubuntu-server | ||
| fabbione | \sh: check the new daily. there was a kernel abi bump | 10:40 |
| \sh | fabbione: well...using flight6 with updates...should work | 10:43 |
| fabbione | yes it should | 10:43 |
| infinity | \sh: The seeds were out of sync, so kernels on all dailies are messed up. | 10:44 |
| infinity | \sh: We just fixed that, so the next round of dailies will be fine. | 10:44 |
| \sh | infinity: ok :) but anyhow I need to deliver some ubuntu servers for amd64 just now...so working around is better right now then to wait for the next cd build run :) | 10:46 |
| infinity | Yeah, just take the daily that built at the same time as Ubuntu Flight 7. | 10:46 |
| infinity | That one's fine. | 10:46 |
| infinity | Or start at Flight-6 and upgrade, if you prefer. Whatever. | 10:46 |
| \sh | hmm..nice issue right now...trying to install it via ILO and after the graphic boot selection...black screen | 10:47 |
| \sh | infinity: just for your info: setting vga mode to 640x480x16 and then booting works...the standard setting does't work when you try to install via ILO remote console | 10:51 |
| \sh | will file a bug after the installation :) | 10:52 |
| infinity | I'd need access to an ILO-enabled machine to debug it, unless you have more info for me than "doesn't work". | 10:53 |
| \sh | infinity: no display but running the installer...looks like the switch from graphics mode to text mode works only in 640x480x16 mode... | 10:55 |
| infinity | Yeah, that's still not enough info to be useful without a machine to look at. | 11:00 |
| infinity | I don't suppose you know anyone who could give me access to an ILOable box for a bit? | 11:01 |

| \sh | infinity: sorry no...all the ILOs here are in mgmt networks which are not accessible from the outside:( | 11:22 |
| infinity | \sh: If you can get me access to just one at any point, I can diagnose and fix the bug, but otherwise, there's probably little point in even filing it. | 11:26 |
| \sh | infinity: let me try something... | 11:54 |

| dyn | problem: at install time I had no network available. later on I edited /etc/network/interfaces but still '/etc/init.d/networking restart' does not pull up eth0. how can I fix this? (the box was installed in server mode so no X11/gui clients are available) | 03:47 |
