karamazovCan anyone point me towards a resource to put a lamp stack on a unbuntu server on ec201:46
jrwrenkaramazov: ubuntu server guide?02:12
karamazovjrwren: I've tried using it but I can't get apache to run...02:12
jrwrenkaramazov: do you get an error? did you open port 80 in ec2 security group?02:13
karamazovNo error - does 80 need to be open for inbound or outbound?02:15
karamazovjrwren: thank you02:19
hazmathallyn_, one oddness with btrfs and lxc (using clone) that i havent figured out.. btrfs-progs won't report the subvolume or snapshot usage, looking over btrfs-progs src, the main delta seems to be quota group related wrt to subvol creation.. just curious if you've run into this before.03:30
hazmati'm trying to use send/receive against the vols, but without btrfs-progs being aware, thats problematic03:31
hazmatstgraber, ^03:39
hallyn_hazmat: nto sure what you mean by 'run into before'.  i've not tried send/receive of vols.  I use 'lxc-clone -B btrfs' a ton every day seems robust so far03:44
hallyn_(only caveat, in precise, is tha ti must use eatmydata to run dpkg and apt-get else it is dog-slow)03:45
hazmathallyn_, sure. but btrfs subvolume list /var/lib/lxc shows nothing.. with lxc-clone -s03:45
hazmathallyn_, i've got /var/lib/lxc setup as a btrfs mount, lxc-clone -s  seems to implicitly pickup btrfs.. as the resulting container takes roughly 7m03:48
hazmatexplictly specifying -B btrfs actually results in rather odd behavior compared to the implicit, either full copy or error (http://pastebin.ubuntu.com/6435693/)03:50
hazmatlikely cause its not a subvolume03:50
* hazmat tries with explicit btrfs on create03:51
hazmathallyn_, nevermind i think its user error. with dedup on the vol accounting for the minimal usage03:53
hallyn_hazmat: ok - sorry i went quiet, my laptop went berzerk03:55
hallyn_but why was precise-base not btrfs, if /var/lib/lxc is btrfs?03:56
hallyn_that sounds like an lxc-create but03:56
hazmathallyn_, it was btrfs, just not a subvolume from lxc-create without the -B, what's also interesting is the implicit behavior with lxc-clone -s, its not the dedup, it is must be taking some form of snapshot i think as it completes in roughly the same time as a subvolume snapshot (0.09s)03:58
hazmatbut whatever form that is, doesn't get reported by btrfs-progs in saucy (currently building git head of those just to compare)04:05

basil_Hi guys would anyone be able to help me troubleshoot using x11vnc to get access to a GUI on Unbuntu 12.04 from XenServer 6.2?08:49
jamespageyolanda, well everytime you need to display that info you have todo an exec which is quite expensive on Java virtual machines09:04
yolandajamespage, a better alternative should be to parse the /etc/os-release file?09:05
jamespageyolanda, I was trying to think of a way todo it in the init script and pass it in as a system property09:06
jamespagethat way its set dynamically on startup - but is then an in-memory read from that point onwards09:06
yolandaso pass this var in the makefile?09:07
jamespageyolanda, no - I'd look for a named system property in the Java code, and pass that in the tomcat7 init script09:21
jamespageif it does not exist, then revert to current behaviour09:22
yolandawell, we have the os.name but it should populate "Linux", setting that to Ubuntu could affect behaviour, right?09:24
jamespageno - use a new property09:27
jamespageyolanda - its trivial to set them on startup in the init script09:28
jamespageother things might rely on os.name09:28
jamespageand os is really owned by the JVM so you won't be able to change it anyway09:28
yolandaok, reading about that because i didn't know this about java, i see09:28
jamespageyolanda, I'd probably add it to JAVA_OPTS in the catalina_sh function in the init script09:31
yolandajamespage, cool, i'll work on it09:34
jamespageyolanda, great -thanks!09:34
yolandathx for the advice09:34
yolandajamespage, trying same build of couchdb for saucy10:07
yolandajamespage, it's problem with trusty, with saucy builds fine10:09

yolandajamespage, trying the tomcat patch. I pass to it properly: /usr/lib/jvm/default-java/bin/java -Djava.util.logging.config.file=/var/lib/tomcat7/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.awt.headless=true -Xmx128m -XX:+UseConcMarkSweepGC -Dos.distribution_name=Ubuntu -Djava.endorsed.dirs=/usr/share/tomcat7/endorsed -classpath /usr/share/tomcat7/bin/bootstrap.jar:/usr/share/tomcat7/bin/tomcat-jul12:27
yolandai.jar -Dcatalina.base=/var/lib/tomcat7 -Dcatalina.home=/usr/share/tomcat7 -Djava.io.tmpdir=/tmp/tomcat7-tomcat7-tmp org.apache.catalina.startup.Bootstrap start12:27
yolandabut then using System.getProperty("os.distribution_name") in code returns null12:27
yolandaam I doing something wrong there?12:27
jamespageyolanda, you can't use os prefix12:27
jamespageits reserved I think12:27
yolandacatalina should be ok?12:27
yolandaor just use something not prefixed?12:27
jamespageI'd do that - not prefixed12:28
yolandaok, let me try this12:28
jamespagethat's java-ish12:28
yolandaannoying thing of tomcat is that it takes ages to rebuild12:29
yolandajamespage, also dealing with couchdb that's written on erlang. Do you know if os::getenv("DISTRIBUTION") should work, if passing that as env var in makefile?12:31
jamespageyolanda, it depends when that call is made12:31
jamespageyolanda, if its runtime then that won't work12:31
jamespageif its build time that should be OK12:31
psivaayolanda: jamespage: is ^ your discussion any chance related to tomcat daemon not running in the trusty server images? and making the smoke failures?12:38
jamespagepsivaa, its not - but that sounds important as well!12:39
psivaajamespage: ok, then i'll report a bug for that12:39

yolandaso jamespage, something is wrong with our approach for Tomcat:-Ddistribution.name=Ubuntu - but then System.getProperty("distribution.name") returns null14:07
yolandai think that this var needs to be defined in catalina.sh script14:10
hallyn_hazmat: ok, looking at the code, I have a vague recollection this was by design.  If you say 'lxc-create -B best' then it will use btrfs if detected, but if you don't specify -B at all, it uses dir.14:11
hallyn_hazmat: note we *used* to always autodetect.  I'd have to check mail archives to remember why it was changed14:12
hallyn_(Of course -B btrfs works too, but -B best lets you fall back to dir if you're not sure whether you'll be on btrfs)14:12
psivaajamespage: the reason for tomcat server issues in the smoke is http://bazaar.launchpad.net/~ubuntu-core-dev/ubuntu-seeds/ubuntu.trusty/revision/2183 according to cjwatson14:30

roaksoaxok, so merging kombu and by default is using librabbitmq for amqp instead of python-amqp15:09
roaksoaxso is this something we want to carry/make default15:09
jamespageroaksoax, unless there is a good reason not to we should upstream align15:10
roaksoaxjamespage: yeah, just making sure we are not gonna affect openstack for some reason15:11
roaksoaxjamespage: i do think however, its use with kombu doesn't have ssl support15:11

jamespagezul, I like to go on about stuff I like16:29
zuljamespage:  hehe16:29
roaksoaxjamespage: doc pointer? :)16:29
jamespagezul, re the MP above - trying to understand the impact of it16:29

jamespagerbasak, save the manual 1000's of line of autoreconf patch that is sometimes required (I used this for openvswitch)16:31
roaksoaxjamespage: yeah i meant more in the way of howto's or transition docs :)16:31
rbasakjamespage: I use dh-autoreconf for that16:31

jamespagejacalvo, hey - zul is working on poking samba @ 4.x into trusty, but its making zentyal uninstallable right now which is blocking migration to the release pocket16:38
jamespagejacalvo, are you guys still actively maintaining package in distro? if so could you take a look and see16:42
jacalvojamespage, mmm, the problem is that the zentyal packages in universe are still using samba 316:43
jacalvoand the newer versions of zentyal that use samba4, are using a custom build of samba4 with bundled libraries...16:44
jacalvoso I'm not sure which is the proper solution here16:44
jamespagejacalvo, so the samba4 package will be disappearing - samba is/has been bumped to 4.0.something already16:45
jamespagejacalvo, we need to unblock the migration - is this something you can work out in the short term? or should we remove zentyal from archive until you come up with a fix16:46
jacalvojamespage, let me discuss this with the zentyal devs, I'll get back to you with news as soon as possible ;)16:46
jamespagejacalvo, thanks - much appreciated!16:47
jacalvojamespage, so, the removal would be only from the trusty archive, right?17:11
jamespagejacalvo, yes - thats correct17:11
jamespageand we can re-introduce later once you have stuff sorted17:11
jacalvoI think it's the safest option, we can guarantee a fix in the short term, because currently we depend not only on a custom samba4 package, we also have patched versions of bind9 and openldap :(17:11
jacalvos/we can/we can't/17:12
jacalvofirst thing to do would be to try to introduce those patches upstream and make it work with the non-bundled version of samba17:13
jamespagejacalvo, agreed - OK - I'll request removal17:13
jacalvothanks!, and sorry for the inconvenience17:13
jacalvojamespage, anyway, maybe removing zentyal-samba is enough17:14
jamespagejacalvo, np - its all just part of the dev cycle :-)17:14

jamespagezul, re the xcp removal stuff17:26
jamespageI think running XCP on Ubuntu is not worth holding onto17:26
jamespagebut running against remote XenServer probably is17:26
jamespagebut thats the same model as VMware - for which we need a no-op hypervisor package for if that makes sense?17:27

sarnoldzerick: compiling the biggest packages you can get your hands on is a decent way to stress a machine. it'll involve disk IO, memory IO, CPU churning..

sarnoldharsh: depending upon what you're trying to accomplish, that might be progamming a web application in ruby on rails or django or tomcat (eww java) -- or it might be programming "native" desktop clients using Qt or GTK with e.g. QML or Python or C++ or C or whatever you like. There's plenty of choices, maybe too many. :)18:04

patdk-wkwell, they have no data turnover18:09
sarnoldmmm, hexacore :)18:09
patdk-wkeverything will go a max of 200MB/sec for them18:09
sarnoldright. most of their systems are going to be idle most of the time, as far as I can guess.18:09
patdk-wkwell, not idle, but processing like 10mbit/sec :)18:09
sarnoldand 8 gigs of ram feels like penny pinching :)18:09

patdk-wkI have installed 32gigs of ram, cause I couldn't actually but the system with less18:10
sarnoldgranted on their scale, pennies need to be pinched. but it doesn't feel like much left over after the buffer cache eats most of it18:10
patdk-wkthe buffer cache is pointless for them18:10
patdk-wkthey won't be rereading data18:11
sarnoldpatdk-wk: well, sure, but that's windows land, where 3.5 gigs is the limit. hehe.18:11
