| 16:59.31 | eightyeight | ok. strange case here: |
| 16:59.51 | eightyeight | my irc vm is on hypervisor #1. i live migrate it to hypervisor #2, so i can reboot #1 to do some maintenance |
| 17:00.02 | eightyeight | the reboot causes the vm to lose its connectivity to the internet |
| 17:00.19 | eightyeight | if the vm is on #2, why should the reboot of #1 affect the vm's network? |
| 17:00.55 | fugue88 | Perhaps vm #1 was just forward the connection to vm #2, as you can't change an existing connection's endpoints? |
| 17:01.14 | eightyeight | not vm #1 and vm #2. there is only one vm. |
| 17:01.36 | eightyeight | the vm was on hyper #1, but now resides on hyper #2 |
| 17:01.42 | fugue88 | Oops, but I think the basic idea is the same. |
| 17:02.18 | Nemus | is hypervisor #1 and #2 on the same lan segment ? |
| 17:02.22 | eightyeight | so you're saying that even though the vm resides on hyper #2, it is still routing over hyper #1? |
| 17:02.29 | eightyeight | Nemus: yes |
| 17:02.40 | fugue88 | eightyeight: My guess would be yes. |
| 17:02.54 | Nemus | maybe the arp tables never updated? |
| 17:02.55 | eightyeight | that goes against all of my intuition, and some docs that i've read |
| 17:03.23 | Nemus | what is the hypervisor? |
| 17:03.24 | fugue88 | And what do the docs say about this? |
| 17:03.26 | eightyeight | is the point of live migration, so you can do maintenance on your hardware without downtime? |
| 17:03.37 | eightyeight | kvm |
| 17:03.57 | fugue88 | eightyeight: I thought it was to balance load between servers and load patterns change. |
| 17:04.02 | fugue88 | Maybe some of both. |
| 17:04.13 | fugue88 | *as load patterns change. |
| 17:04.54 | Nemus | my guess would be you had a networking issue not a hypervisor issue |
| 17:04.56 | fugue88 | Anyway, I don't know, just saying what my guess is. You can check that against either you intuition or some investigation, your choice. :) |
| 17:05.08 | eightyeight | yeah. curious if anyone has faced this |
| 17:05.19 | Nemus | I would have to see your hypervisor #2 setup |
| 17:05.42 | eightyeight | Nemus: each hypervisor has 2 nics in a bond, using 802.3ad. off that bond is a bridge device for the vms |
| 17:05.44 | Nemus | see if the nic came up |
| 17:05.46 | eightyeight | no vlans |
| 17:06.29 | eightyeight | i want to live migrate everything back, and do maintenance on box #2, but fear of going through the same problem |
| 17:09.43 | Nemus | I would create a test vm and migrate it see if the arp tables update and try and follow the network traffic at layer two. |
| 17:09.50 | Nemus | anyway just an idea |
| 17:11.02 | eightyeight | yeah. agreed. i had thought the same. |
| 17:11.11 | eightyeight | i would not expect this behavior though |

| 17:42.19 | Tene | eightyeight: did it recover before or after hypervisor 1 was back up? |

| 21:06.11 | harleypig | Is there a way to dump the top level packages using rpm? I need to generate a list of installed packages to be used to install a similar system, but I don't want to list 450+ packages in a script if I don't have to. |
| 21:07.41 | goozbach | I've always used rpm -qa and plopped that into %packages |
| 21:09.32 | harleypig | <PROTECTED> |
| 21:09.52 | Jayce^ | install less crap |
| 21:10.43 | harleypig | For example, somepackage is required by some other package, but it's never actually installed using a direct yum install. I want to avoid putting that in %packages |

| 21:12.02 | ezakimak | anyone know how to make xset changes persist? (specifically key repeat delay?) |
| 21:12.31 | fugue88 | .xinit ? |
| 21:12.57 | jlp_work | ezakimak: you mean persist from login to login? I put that stuff in .xsession. depends on your desktop environment, I suppose. |
| 21:12.58 | fugue88 | I think that's what that script is called. |
| 21:13.49 | ezakimak | hrm. i don't have either atm |
| 21:13.58 | jlp_work | what desktop environment do you use? |
| 21:14.06 | fugue88 | Oh, .xinitrc, but that may not be the one you want, it's kind of low-level. |
| 21:14.08 | ezakimak | it used to work, something changed and now it comes up different |
| 21:14.14 | ezakimak | kde |
| 21:14.30 | ezakimak | i recall setting it somewhere ages ago (years) |
| 21:14.30 | jlp_work | gah. I haven't used kde in fifteen years. |
| 21:14.59 | ezakimak | i hate it when updates make little usability changes like this. |
| 21:15.16 | jlp_work | I think kde has something like .kde/Autostart |
| 21:15.27 | jlp_work | you might be able to just drop a shell scriptlet in there |
| 21:16.17 | fugue88 | There may also be a GUI to set programs to start on login or similar. |
| 21:16.25 | goozbach | harleypig: you might be able to get somethign out of rpmquery |
| 21:16.26 | fugue88 | I set my keyboard map in xfce that way. |
| 21:16.28 | ezakimak | oh, found it in one of my old xorg.conf files |
| 21:16.31 | goozbach | about only nodes |
| 21:16.33 | goozbach | no tree |
| 21:17.41 | ezakimak | hrm. but i use evdev now. |
| 21:17.42 | jlp_work | ezakimak: that would set it system wide (for all users). I'd avoid putting user specific customizations in there, personally. |
| 21:17.51 | ezakimak | i am the user |
| 21:18.11 | jlp_work | try the .kde/Autostart/ folder... drop a shell script in there, log out and back in and see what happens. |
| 21:18.32 | ezakimak | yeah, i'll test it next time. (i logout/in very rarely--it's a painful process) |
| 21:18.52 | jlp_work | good luck. let us know how it goes. |
| 21:19.03 | ezakimak | if i remember. (hopefully it'll be months) |
| 21:26.49 | programmerq | so I had a fun conversation today, it was more or less: "so your apache server is just closing the connection when this exact request happens". "no that's the wrong IP you're using". "no it really isn't. it's the same IP that we're using for all the requests that work". "oh okay, I looked in logs and it's segfaulting" "yeah, that sounds bad. it's probably a bug in mod_php". "I just checked disk space, and it's |
| 21:26.51 | programmerq | fine". "no, segfaults are about memory management problems". "that's why I checked the disk!" |
| 21:28.29 | goozbach | yum utils may have something as well |
| 21:31.47 | ezakimak | programmerq, huh? |
| 21:31.58 | harleypig | goozbach: thanks for the rpmquery hint ... this might do it: for i in $(rpm -qa --qf '%{NAME} ') ; do rpmquery --whatrequires $i ; done | grep 'no package requires' |
| 21:32.33 | programmerq | ezakimak: basically they had mod_php segfaulting apache and the first thing they wanted to do was check that the disk wasn't full |
| 21:33.02 | ezakimak | i got that. my huh was in disbelief of their ineptness |
| 21:33.06 | programmerq | oh, okay |
| 21:33.16 | programmerq | but yup |
| 21:33.24 | programmerq | "huh?" sums it up. |
| 21:34.25 | ezakimak | one could cause the other (in either direction), but that is far from most likely. |
| 21:35.11 | programmerq | I challenged him on it and when I explained that disk!=ram he said that virtual ram is on disk |
| 21:35.11 | ezakimak | LOL |
| 21:35.22 | programmerq | so he thought that it was segfaulting because the server was swapping |
| 21:35.35 | programmerq | every time on the same request |
| 21:35.41 | programmerq | but not on other types of requests |
| 21:35.44 | programmerq | sighs |
| 21:35.54 | ezakimak | face palm. |
| 21:36.14 | ezakimak | he clearly lacks key knowledge in his chosen field. |
| 21:36.17 | programmerq | I'm going to come home with a permanent imprint of a hand in my face |
| 21:36.31 | programmerq | ezakimak: yes, this particular group has that in common |
| 21:36.34 | programmerq | all of them |
| 21:36.44 | ezakimak | sell him a $900 mouspad upgrade. |
| 21:37.10 | ezakimak | or a bucket to catch tokens when they unplug their network cable. |
| 21:38.39 | Tene | programmerq: ;_; |
| 21:39.00 | programmerq | I might possibly write this up and file it away for a few years and then submit it to the daily wtf |
| 21:39.09 | ezakimak | why wait? |
| 21:39.24 | programmerq | don't know if anyone in their group reads the dailywtf |
| 21:39.31 | programmerq | and I don't want management freaking out about it |
| 21:39.42 | programmerq | I'd have to do a better job of writing it up to submit it there |
| 21:39.56 | ezakimak | i highly doubt they even know about that site |
| 21:39.59 | programmerq | which means I could possibly give out some identifying info about the group |
| 21:40.03 | programmerq | or the individual |
| 21:40.09 | ezakimak | just anonymize it |
| 21:40.19 | programmerq | of course I'd do that |
| 21:40.28 | programmerq | but if someone in their group saw it |
| 21:40.34 | programmerq | they'd know it was them I was talking about |
| 21:40.42 | programmerq | but in a couple years, it wouldn't be so obvious. |
| 21:41.33 | ezakimak | so, if they see it, let them learn their lesson. |
| 21:41.42 | programmerq | I could get dinged by HR though |
| 21:41.46 | programmerq | which I'd rather avoid |
| 21:41.48 | programmerq | shrugs |
| 21:41.58 | ezakimak | well, we got a laugh at least. |
| 21:42.03 | programmerq | indeed |
