[03:38] <vlad_starkov> Question: Just installed Ubuntu 12.04 LTS 64bit. On boot it freezes and shows "BUG: soft lockup - CPU stuck for 21s". Anyone know what is that?
[03:40] <Patrickdk> standard, kindof
[05:37] <vlad_starkov> Question: Does anyone know what the hell is that http://cl.ly/image/310g2D1K462E ? "BUG soft lockup - CPU#0 stuck..."
[05:41] <sarnold> vlad_starkov: does it eventually progress to fully-booted?
[05:41] <vlad_starkov> sarnold: no
[05:41] <vlad_starkov> sarnold: I've installed Ubuntu 12.04 on Supermicro 6015B-TB with 2xXeons E5345 / 16GB RAM/ RAID 10 (4TB)
[05:42] <vlad_starkov> The same error appears on 64bit and 32bit Ubuntu 12.04
[05:42] <vlad_starkov> is it possible that 4Tb partition is too big for Ubuntu?
[05:42] <vlad_starkov> Or 32Gb SWAP is too big?
[05:45] <sarnold> vlad_starkov: 4TB ought to be fine.. 32 gigs ought to be fine (my laptop has 16 gigs without trouble anyway..)
[05:45] <sarnold> oh drat..
[05:48] <sarnold> vlad_starkov: 4TB ought to be fine.. 32 gigs ought to be fine (my laptop has 16 gigs without trouble anyway..)
[05:48] <sarnold> (and the last limits I heard about on swap were removed back in 2.3.3...
[05:49] <vlad_starkov> sarnold: so what is the cause of the problem?
[05:51] <sarnold> vlad_starkov: I believe what it is reporting is that two CPUs have requested the same data structures, and perhaps #4 locks A and needs B, while #5 has locked B and needs A
[05:51] <sarnold> vlad_starkov: one is executing modprobe, the other is executing upstart-udev-bridge, which -might- also be trying to load modules .. 'modprobe' might have been kicked off by the 'ufw' during boot
[05:52] <vlad_starkov> sarnold: it could be that... at least it looks quite realistic
[05:53] <vlad_starkov> sarnold: I use Ubuntu for a few years on the beginner-class servers, it's my first Ubuntu install on pretty powerful hardware and I got this
[05:53] <sarnold> vlad_starkov: just as a dirty hack you might be able to add 'sleep 1' to the /etc/init/ufw or similar to try to get it to run in a different order...
[05:53] <vlad_starkov> sarnold: how can I access the file system?
[05:54] <vlad_starkov> It's encrypted RAID with LVM
[05:54] <sarnold> vlad_starkov: you can try booting with maxcpus=1
[05:54] <vlad_starkov> sarnold: not baf
[05:54] <sarnold> vlad_starkov: or "nosmp". Though that might trigger other bugs...
[05:54] <vlad_starkov> sarnold: where can I get full list of boot parameters?
[05:55] <vlad_starkov> sarnold: what should I check in BIOS?
[05:56] <sarnold> vlad_starkov: bootparam(7) has many; the linux kernel source file Documentation/kernel-parameters.txt has more
[05:56] <sarnold> vlad_starkov: I wouldn't bother with bios options...
[05:58] <vlad_starkov> sarnold: Am I right that I selected SATA enhanced AHCI in BIOS?
[05:58] <sarnold> vlad_starkov: yes that should be good
[05:58] <vlad_starkov> OK
[05:59] <vlad_starkov> IN BIOS there are parameters like "Adjacent Cache Line Prefetch", "Hardware Prefetcher", "Execute Disable Bit", "Core-Multi-Processing" and so on
[06:00] <sarnold> too many options :)
[06:01] <vlad_starkov> sarnold: so I'll try to play with them
[06:01] <vlad_starkov> sarnold: thank you for you help though
[06:02] <sarnold> vlad_starkov: I doubt those specific options would be involved...
[06:56] <Quest> what is PUT method besides GET and POST and how is it different. Is there a PULL method also?
[06:56] <Quest> in http^
[06:57] <sarnold> hey Quest :) PUT is like a file upload; POST can be used for forms and the like, but PUT is really only good for a single data value. I don't know if anyone uses it...
[06:58] <Quest> sarnold I was in the image the POST is used for file uploads like multipart
[06:59] <Quest> sarnold hi!
[07:04] <Quest>  what are the use cases of PUT?
[07:04] <Quest> is there a PULL too? i heard about it but didnt caught that in any docs.
[07:05] <sarnold> Quest: PUT would probably be used in a file storage system similar to amazon's s3 or backblaze's http file storage thing
[07:06] <sarnold> Quest: all the http 1.1 verbs are briefly described here: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
[07:12] <Quest> hm.
[07:12] <Quest> thanks
[08:18] <rbasak> Quest: also see: REST
[08:29] <rbasak> jamespage: what do you think about bug 1245113? It's in main. SRU for Saucy absolutely needed or shouldn't be permitted?
[08:36] <vlad_starkov> Question: While installing Ubuntu, there is a step for installing additional software. In case I choose "Manual package selection" the aptitude will be launched. Is it possible to add repositories for aptitude to install some additional software?
[08:53] <jamespage> rbasak, it might be permitted; its fairly self contained
[09:13] <Quest> rbasak thx
[09:25] <NaGeL> hello i got this problem: http://askubuntu.com/questions/382592/my-postfix-server-became-a-spam-server-how-can-i-fix-this and answer says nuke it, and start from 0. does that mean to reinstall the whole server?
[09:33] <foo357> Hello, is anyone here familiar with creating disk images / restoring disks?
[09:36] <foo357> When I create a disk image, can I save the resulting file to said disk? (I've got a one-disk machine)
[09:36] <foo357> or would it cause some funny behaviour?
[09:38] <rbasak> foo357: that would cause corruption. Don't do that if you want a good image.
[09:45] <blueking> have problem with ethernet on ubuntu server... tho when I type  http://192.168.1.1 I can logon asus router but  can't enter  net   what to look at     installed shorewall on box, problem are that I can't  use apt-get update/install

[10:06] <foo357> rbasak: the harddrive I want to create a disk image of is encrypted (using the options in the ubuntu installation disc), will encryption be preserved in the disk image?
[10:19] <TazmainianDevil> hi all I am running ubuntu server 12.04. I am running a media wiki on it. When i open the page from the server it renders fine. When I open it from another computer the whole left side of the page is missing?
[10:34] <blueking> think I found  what my problem are   ip route ls  shows  'default via 192.168.2.1  dev p3p1'   but  device that are connected to net are p2p1
[10:45] <blueking> can someone tell me if there should be more than one IP in shorewall masq file ?
[11:11] <blueking> what dhcp server to go for ?
[11:38] <blueking> could someone tell me what makes network interface to be primary secondary  in /etc/network/interface file ?
[12:48] <blueking> lwhat I do when apt-get upgrade  and gets this initctl: unknown job: mysql ?
[13:34] <blueking> bleh   ubuntu server install was fucked up had to perform reinstallation of it \o/
[13:42] <Rory> 3/buffer close
[14:11] <blueking> I have a question about  shorewall /etc/shorewall/interfaces  :     If I am right   device p2p1  connects to net, device p3p1 are local net     I have to  install dhpc  server to give connected units on localnet  their IP's    and then I have to setup dhcp server   but do I need to do something with /etc/network/interfaces ?
[14:16] <zul> jamespage:  i dont even know why backuppc is seeded
[14:16] <zul> jamespage:  well i know why but its a dumb reason
[14:23] <jamespage> zul, that sounds like +1 to me
[14:23] <zul> jamespage:  it is
[14:33] <zul> jamespage:  cinder uses a fork of rtslib
[14:35] <hallyn_> jamespage: is that saying wireless-tools and wpasupplicant are in there now?
[14:35] <hallyn_> i suppose i could see that being an inconvenience (bugged me frequently in lucid), but mainly for developers.
[14:36] <hallyn_> though i have some headless servers that run wireless, and they're becoming more populear - but so far they all still including a wired nic.
[14:46] <jamespage> zul, that should be converged now I think
[14:46] <jamespage> the licensing issue was resolved in the original project
[14:47] <jamespage> hallyn_, yes - wireless tools and wpas are on the ISO right now
[14:50] <zul> jamespage:  ah so it is
[15:05] <Darkstar1> hello all. How do I find out my hard and soft limits for my server (12.04)
[15:06] <jrwren> type ulimit -a
[15:06] <jrwren> and ulimit -aH for hard
[15:07] <Darkstar1> jrwren: thanks
[15:12] <jamespage> zul, subunit seems a little stuffed in trust
[15:12] <jamespage> y
[15:13] <zul> jamespage:  broken?
[15:13] <jamespage>   File "/usr/bin/subunit2pyunit", line 24, in <module>
[15:13] <jamespage>     from testtools import StreamToExtendedDecorator, DecorateTestCaseResult, StreamResultRouter
[15:13] <jamespage> zul, the scripts have python3.3 but the package depends on python2 libraries
[15:13] <zul> erm...ok ill have a look at it
[15:14] <jamespage> zul, noticed when I was patching up neutron
[15:14] <zul> ack
[15:14] <jamespage> (needed a refresh of patches only so pushed as a trivial)
[15:14] <jamespage> zul, (un)fortunately it has a || true
[15:15] <zul> jamespage:  yeah the nova tests in trusty has the same (im not sure whats happening with the database in the tests)
[15:21] <jamespage> zul, let me log the subunit thing as a bug as well
[15:21] <zul> jamespage:  please
[15:26] <jamespage> zul, bug 1255571
[15:28] <jamespage> zul, we can get rid of the quantum-* transitional package now right?
[15:28] <jamespage> that's a grizzly->havana upgrade transition I think
[15:28] <zul> jamespage:  yes i think so
[15:31] <jamespage> zul, https://code.launchpad.net/~james-page/neutron/drop-quantum-packages/+merge/196924
[15:38] <blueking> wonder why my windows box connected to ubuntu-server  gets dhcp-server 255.255.255.255
[15:39] <blueking> oh it was fixed when i restarted dhcpd server
[16:11] <zul> jamespage:  https://code.launchpad.net/~zulcss/cinder/icehouse-ftbfs/+merge/196932
[16:25] <jamespage> zul, query on that MP
[16:25] <zul> jamespage:  yep
[16:27] <zul> jamespage:  yeah i meant to drop it...it has namespace conflicts
[16:28] <jamespage> zul, +1
[16:28] <zul> jamespage:  thanks
[16:28] <jamespage> zul, want me to take swift?
[16:28] <jamespage> nm - thats the sphinx  build bug
[16:28] <zul> jamespage:  if you want it has docs build problems though
[16:50] <blueking> just wonder    doesn't dhcp server send  gateway ip to connected devices/laptop/pc ?
[16:57] <kwoot> Where can I send a bugreport with fix regarding a vmbuilder instance with postgresql-server ?
[17:01] <blueking> hmm
[17:43] <blueking> ok this looks better :)
[17:43] <blueking> now I am connected through ubuntu-server shorewall
[18:29] <zul> jamespage:  subunit fixed
[18:35] <jamespage> zul, excellent
[18:57] <blueking> had to shutdown  shorewall to be able to use apt-get    seems firewall somehow blocks  apt-get  even when ping worked right from box itself
[19:12] <patdk-wk> blueking, configure it correctly
[19:12] <patdk-wk> you probably are missing the policy, accept fw net
[19:16] <pmatulis> looks like slapd 2.4.31 is really dear to somebody's heart in debian-land
[19:19] <blueking> patdk-wk:  ok I'll loook into it
[19:21] <blueking> patdk-wk:    loc net accept,  net all drop, all all  reject    dmesg reports that it ends up at last line  rejected
[19:24] <blueking> patdk-wk:  got it fixed :)
[19:58] <Corey> scrollback end
[21:16] <blueking> hmm  got serious problem after  had raid  array on another linux distro  and mdadm didn't seem to have mdadm --zero-superblock /dev/sdc
[21:16] <blueking> superblock wasn't recognized ?
[21:19] <strixUK> any suggestions about how i might keep packages between two systems synchronised?
[21:21] <blueking> I get bad superblock on hdd  how to clean it ?
[21:24] <blueking> on mdadm tutorial   there was mdadm --zero-superblock    is it still there ?
[21:27] <ikonia> why would you zero a superblock
[21:29] <blueking> because I fail mount hdd
[21:29] <ikonia> but zero'ing the superbblock won't fix that
[21:30] <blueking> it's used after delete of raid array ?
[21:30] <ikonia> oh, you want to destroy the array
[21:30] <ikonia> I thought you where trying to fix a file system
[21:31] <blueking> well I've failed  mount/create raid array  after those two hdd's was used  in raid array in another linux distro
[21:31] <ikonia> mount and create array are two very different things
[21:31] <ikonia> I'd think about and clarify what you want to do
[21:33] <strixUK> is there any way to find out what created an entry in passwd or group?
[21:33] <strixUK> i've just created a fresh ec2 instance and would like to get it looking as close to our main server as i can
[21:33] <ikonia> the username normally gives you a clue
[21:33] <strixUK> "admin" :)
[21:33] <ikonia> why do you need to know what greated it then, creating the user accounts from the old password file is simple
[21:34] <strixUK> (group admin)
[21:34] <ikonia> that's an ubuntu default group - legacy now
[21:34] <strixUK> ah right
[21:35] <strixUK> ditto lpadmin?
[21:36] <ikonia> thats printing
[21:36] <blueking> ikonia: tested some stuff seems I've done something wrong in fstab
[21:36] <ikonia> strixUK: to be honest, what does it matter, just copy the uid/gid and re-create the users
[21:36] <blueking> ikonia:  could manual  mount those hdd's
[21:36] <blueking> gets error when start up linux
[21:36] <ikonia> you should not be maually mount hard disks that are part of a raid array
[21:37] <strixUK> sure.  i didn't install any print services on the current machine, so i'm guessing it was part of the base pkg.  "find / -group lpadmin" reports nothing anyway.
[21:37] <blueking> for moment they are not in array
[21:37] <ikonia> strixUK: cups
[21:37] <blueking> but will be
[21:37] <strixUK> ikonia: this is a backup server we're running in parallel
[21:37] <ikonia> strixUK: so ?
[21:40] <strixUK> what's more important is keeping the installed packages in sync between them.  i could do it manually, but it'd be nice to have it done automatically.  looks like i can do something with dpkg --get-selections.
[21:40] <strixUK> i wonder if that will maintain the same state that aptitude generates
[21:41] <ikonia> surly just getting an install package list and looping through them would just make it the same
[21:41] <ikonia> or actually taking a proper backup of the source machine and restore to new target
[21:43] <strixUK> ikonia: all possibilities worth considering
[21:44] <strixUK> sounds like there's no existing automated way of doing this, and tbh i probably won't install much new stuff on the live machine anyway, so doing it manually wouldn't be that hard.  automating a check to compare what's installed probably isn't difficult either.
[21:45] <strixUK> it's complicated slightly by the fact that the origins of these two machines are not identical.  they're both ubuntu 12.04, but one's the EC2 AMI that's evidently been customised somewhat for EC2.
[22:58] <blueking> hmms
[22:58] <blueking> shorewall not starting by default on startup of ubuntu ?
[23:52] <mvhenten> Hi, I'm having trouble with ufw: ufw enable
[23:52] <mvhenten> ERROR: Could not load logging rules
[23:52] <mvhenten> I'm puling my hair because I just can't get a smtp server open
[23:52] <sarnold> mvhenten: are there any errors in dmesg?
[23:53] <mvhenten> I see things like [UFW BLOCK]
[23:53] <mvhenten> but nothing that hints me to what is wrong with ufw
[23:53] <mvhenten> also ufw status verbose gives me: ERROR: problem running ip6tables
[23:54] <mvhenten> I've been googling but mostly found outdated helpme's and some notes about re-compiling the kernel
[23:54] <mvhenten> but AFAIK this should just work right?
[23:55] <sarnold> mvhenten: it usually does Just Work..
[23:55] <mvhenten> yes, it's not the first server I'm using ufw with
[23:55] <sarnold> mvhenten: since so much of iptables functionality is done via modules, I was wondering if there were errors loading the kernel modules
[23:56] <sarnold> it could be that your current running kernel doesnt have the required modules on disk any more if "old" kernel pcakages have been uninstalled...
[23:56] <mvhenten> might need to install something then?
[23:57] <mvhenten> kernel is 2.6.32-042stab076.8
[23:57] <mvhenten> that's a bit old
[23:57] <mvhenten> right?
[23:58] <bekks> It is an vps kernel built by your hoster.
[23:58] <sarnold> check dpkg -l linux-image-`uname -r`
[23:58] <sarnold> oooooo
[23:58] <bekks> I bet you cant change it without breaking your vps.
[23:58] <sarnold> are you in a container, rather than a VM?
[23:58] <mvhenten> ah I see
[23:58] <mvhenten> No packages found matching linux-image-2.6.32-042stab076.8.
[23:59] <mvhenten> I feel like im in a echo well
[23:59] <mvhenten> not a server
[23:59] <sarnold> owww :(
[23:59] <mvhenten> so it's really a question for my hoster then
[23:59] <mvhenten> I've never had this kind of issue on normal hardware or an aws box
