First of all kudos for the LTSP5 packages. [12:41] Banana: kudos go to ogra & sbalneave mainly :) [12:42] I have managed to get everything working on top of Xen amd64 which was kind of a nightmare [12:42] i have a small issue [12:43] i can't seem to find it in the bugzilla so i figured i asked here. [12:43] when i shutdown a client, the / gets umounted too soon [12:43] and the halt script cannot be executed. [12:44] there are I/O errors on nbd-client which complains about a closed socket [12:44] hence the machine hangs just before calling halt [12:45] (non xen here, on a real diskless client). === PriceChild [n=pricechi@ubuntu/member/pdpc.supporter.student.PriceChild] has joined #edubuntu [12:48] uhhh i thikn i found the cause [12:49] the S60umountroot in runlevel 0 is trying to remount / readonly. === tck [n=tck@213-202-170-34.bas504.dsl.esat.net] has joined #edubuntu [12:49] i'll try to deactivate it. === spacey [n=herman@ubuntu/member/spacey] has joined #edubuntu === juliux [n=juliux@ubuntu/member/juliux] has joined #edubuntu [01:29] Banana, thats feisty ? [01:30] no gutsy [01:30] i found the culprit [01:30] the script sendsigs which sends killall -15/-9 to everyone [01:30] it kills nbd-client early in the shutdown process [01:31] there is a file /var/run/sendsigs.omit [01:31] i'm trying to add pidof nbd-client in it to see [01:31] well, bug 126444 was supposed to be fixed [01:31] Launchpad bug 126444 in ltsp "[gutsy-tribe2] on tty0 fails to shut down ltsp thin clients" [Undecided,Fix released] https://launchpad.net/bugs/126444 === ludoRA [n=Ludovic@mut38-5-82-246-189-159.fbx.proxad.net] has joined #Edubuntu [01:32] i'll go check the bugreport; thanks for the pointer. [01:33] /opt/ltsp/i386/etc/rc6.d/ and /opt/ltsp/i386/etc/rc0.d/ should only have the shutdown/reboot scripts [01:33] at least for all ltsp-build-client runs after version 5.0.25 [01:35] hooo [01:35] (note that wont be the case if you built your client chroot with an older version) [01:35] that might be why. [01:35] i built the image early in gutsy. [01:35] yeah [01:35] and then chroot in it and dist upgraded [01:36] you should rebuild with the recent version :) [01:36] there are somw steps ltsp-biild-client performs that we cant do on upgrades [01:36] yes its understandable. [01:37] thanks for the hint. [01:39] also note, if you dist upgrade the chroot, you need to run ltsp-update-image [01:39] (the image is whats served now, the chroot is only for maintenance) [01:41] yes i saw [01:41] the speed up is amazing [01:41] bravo :) [01:41] (for the boot process) [01:41] :) [01:42] it has its drawbacks [01:42] i.e. you have to rebuild the image after changes [01:42] :) [01:42] yes but it seems to make better use of the bandwidth than nfsroot [01:43] yeah [01:43] its a lot faster and smaller [01:43] which matters to me as I have ~50 - 75 diskless pc with raging student working on it at all time. [01:43] it puts some extra load on the client cpu for unsquashing though... but thats only affecting the boot [01:43] and only 100mb connection [01:44] oh, yeah there it surely matters [01:44] i also tested with a xen domU thin client (living on the same machine as the ltsp server) [01:45] works allmost like a charm.

[03:04] I did some testing on the weekend. Localdevs seems to be working great! Thanks for the upload. [03:06] pulling my hair out over ltsp-update-image [03:07] that inetd/port code is such a bad mess [03:08] yeah, I improved it a little, but it's kind of a sticky problem. [03:08] What can I help with? [03:08] we have two places that need to be identical all the time (PXE and inetd) [03:09] beyond that there are x special cases that need to be taken into account [03:09] Oh, by the way, couple of minor bugs squashed on the weekend, most important one related to X_RAMPERC. ulimit -v isn't there under dash's shell, so changed it to ulimit -m [03:09] we also need to make sure that we always exit 0 ... unless there is no image [03:10] ah, thats good [03:10] Hey, something else I was wondering. [03:10] yeah, i found that mkfifo isnt in the d-i environment :/ [03:10] have to use mknod ... grrr [03:12] I did some testing, and on all the boxes I tested, an X_RAMPERC=80 makes sure nothing bad happens, kills firefox on insane web pages, etc. I was wondering, should we think about setting a default X_RAMPERC in ltsp_config? Might help to elimintate some of those "my workstation locks up for no apparent reason" type bug reports? [03:12] could go into the initramfs code that checks for low ram [03:13] heh ram < 512m then X_RAMPERC=80? [03:13] lol [03:13] I tested that insane website that Jim K posted [03:14] it allocates, like 512 megs of pixmaps! [03:14] well, i was planning to release with an empty lts.conf so it should be set elsewhere [03:14] (read we'll need an override var for that ) [03:14] NO_RAM_LIMIT [03:14] or so [03:15] or X_RAMPERC=0 disables it [03:15] Well, or X_RAMPERC = 100? [03:15] RAMPERC's such a bad name. [03:15] What else can we call it? [03:15] so people not wanting it can switch it off [03:15] sure = 0 [03:15] MAX_USED_RAM ? [03:15] MAX_RAM ? [03:16] RAMLIMIT [03:16] X_MAX_RAM? [03:16] X_RAMLIMIT [03:16] well, you set all ram [03:16] I like that [03:16] not only X's [03:16] No, just X's [03:16] it's done in the ldm [03:16] so it won't affect other things. [03:17] doesnt ulimit set kernel params ? === monteslu [n=monteslu@ip68-109-171-73.ph.ph.cox.net] has joined #edubuntu [03:17] Not as far as I know. Just that process and all subprocesses [03:18] so we set it in the ldm screen script, it should set for that process, and children. [03:18] ah, ok [03:18] well, just because we're root === jsgotangco [n=JSG@smtp01.globe.com.ph] has joined #edubuntu === jsgotangco [n=JSG@ubuntu/member/jsgotangco] has joined #edubuntu [03:22] sbalneav, cant we just read /proc/meminfo and automtically limit to the ramsize ? [03:22] or better ramsize + swapsize [03:22] seems more elegant somehow [03:23] and have a switch tghat only en or disables that fucntion [03:29] That's what we do [03:29] The question is just WHERE you set the limit [03:30] if you set it too close to the max, some things don't like it. If you set it too low, you're not making full use of the ws's resrources. [03:31] we add up free ram and free swap. And though some (long) testing this weekend, I found 80 makes the best sense. [03:31] leave a 10% buffer ? [03:31] 80 doesnt make sense on a client with 256M and 512M nbd swap in a tmpfs :) [03:32] i'd go with a certain percentage below max === mode/#edubuntu [+o ogra] by ChanServ === ..[topic/#edubuntu:ogra] : Order: http://shipit.edubuntu.org || Edubuntu - the education version of Ubuntu || http://www.edubuntu.org | Wiki: http://wiki.edubuntu.org/EdubuntuWiki | MEETING: every Wednesday see http://wiki.edubuntu.org/EdubuntuMeetingAgenda | feisty (7.04) is released, see http://www.edubuntu.org/Download [03:33] not friday anymore :) === mode/#edubuntu [-o ogra] by ogra [03:33] Well, what I was coming across was that, if I set it much above 85, mozilla would crash, and the desktop would return, but the mouse and keyboard would be frozen. If, on the server, I pkilled the user, the desktop would recyle, but the mouse and keyboard would still be latched. At 80, I found everything worked as expected. [03:34] ok, maybe we can do some math, and set some sensible values. I'll put some thought into it today. Should we put the code in ltsp_config? That'd be the simplest. [03:34] at with what physical ram size ? [03:34] s/at/at 80/ [03:34] yeah, physical ram size [03:34] i.e. if you've got 512 ram, probably 95 is fine [03:35] only ? [03:35] why not more ? [03:35] 98 [03:35] I'd have to play around with some values. [03:35] how much phys ram did you have on the machine you tested 80 on ? [03:35] 256 [03:35] urgh [03:35] 32 meg swap [03:35] thats a huge waste [03:36] we probably need 20M for everything !X [03:36] so you would have 150M idling there [03:37] 256 + 32 * .8 = 230 meg [03:37] 80 is percentage ? [03:37] yeah === ogra thought you talk about MB [03:37] yeah, percentage === ogra slaps forehead [03:37] ramperc :) [03:37] ram percentage :) [03:38] sorry, better ignore me today [03:38] lol, NP === jsgotangco [n=JSG@ubuntu/member/jsgotangco] has joined #edubuntu === ogra thought ramperc == ram per client [03:38] :) [03:38] ok, then 80 is perfect indeed := [03:38] :) [03:39] Anyway, merge from me now, so we get the default behavior of it not being set at all, and then I'll fool around and try to set a sane value based on ram in the client, swap size, etc. [03:39] did you make a change the last hour ? [03:39] no [03:39] i just merged this mornoing [03:39] *morning [03:39] Effecient as always :) [03:39] They're not paying you enough :) [03:40] i just want -update-image half way sane before i package it [03:40] else the package would be up already [03:40] ok, I'll quit bending your ear, and let you get to it :) === froud [n=sean@dsl-242-191-75.telkomadsl.co.za] has joined #edubuntu === TelnetManta [n=benwilli@72.159.132.4] has joined #edubuntu === bddebian [n=bdefrees@63.81.56.182] has joined #edubuntu [04:27] Heya === bkerr [n=bkerr@c-69-241-246-187.hsd1.mi.comcast.net] has joined #edubuntu === boyam [n=boyam@208.104.11.156] has joined #edubuntu === cliebow_ [n=cliebow@smoothwallkludge.ellsworth-hs.ellsworth.k12.me.us] has joined #edubuntu === LaserJock [n=mantha@ubuntu/member/laserjock] has joined #edubuntu === Rondom [n=Rondom@p57A94DB1.dip.t-dialin.net] has joined #edubuntu === bryang [i=sgartner@nat/hp/x-f93a923fb6069640] has joined #edubuntu === bryang [i=sgartner@nat/hp/x-1ea7e60ef4976f7e] has joined #edubuntu === juliux [n=juliux@ubuntu/member/juliux] has joined #edubuntu === [1] sebastian [n=sebastia@wrzb-590ce14b.pool.einsundeins.de] has joined #edubuntu === [1] sebastian [n=sebastia@wrzb-590ce14b.pool.einsundeins.de] has left #edubuntu [] === Mez [n=Mez@ubuntu/member/mez] has joined #edubuntu === ogra [n=ogra@ubuntu/member/ogra] has joined #edubuntu [08:19] hi ogra [08:19] hey [08:20] ogra: how was your weekend?
