[03:31] <neonixcoder> Hi team,
[03:32] <neonixcoder> I am upgrading from 10.04 to 12.04.. but middle of installation after kernel upgrade, my system is rebooting with out any warning.. And once its boots I am getting kernel panic..
[03:34] <neonixcoder> This is happening on already existing system. I tried on a new machine with same set of hardware and configs. At this time, the upgrade went smoothly.
[03:34] <neonixcoder> Any suggestion where should I check so that it will not reboot after kernel upgrade?
[04:42] <sarnold> neonixcoder: were you able to capture any kernel messages?
[04:44] <neonixcoder> yes sarnold..
[04:44] <neonixcoder> one min, let me write it down here..
[04:44] <sarnold> neonixcoder: can you pastebin them somehwere?
[04:44] <neonixcoder> sure..
[04:44] <neonixcoder> my bad..
[04:44] <neonixcoder> will do that
[04:45] <neonixcoder> Its a single line "kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)"
[04:46] <neonixcoder> sarnold: I want to avoid it instead of correct it. Right now I am testing it in  lab.
[04:47] <neonixcoder> so in production, upgrade should go smooth
[04:47] <sarnold> neonixcoder: hmm, do you need any 'funny' modules to mount your root filesystem on your hardware?
[04:48] <neonixcoder> sarnold: I did not get you..
[04:48] <patdk-lap> do you have some kind of raid card, flash thing
[04:49] <patdk-lap> using something other than onboard sata ports
[04:57] <neonixcoder> pdtdk-lap:No such cards, but I install it on a small cf card
[04:57] <neonixcoder> which is 2gb
[04:58] <sarnold> hmm, reminds me of my pandaboard es; after roughly a year it started crashing under heavy io load and then eventually started crashing rouhgly once a day..
[04:59] <sarnold> replacing the sd card was sufficient to fix it
[04:59] <sarnold> neonixcoder: can you try something like badblocks on the card on a different system?
[05:07] <neonixcoder> sarnold:the funny part is.. I am able to upgrade on the same machine with same CF card which is a fresh install from 10.04 to 12.04
[05:07] <neonixcoder> sarnold:So I thought some where there could be a setting my old image where it reboots once kernel is update(I guess)
[05:09] <sarnold> neonixcoder: none that I can recall :/
[05:10] <neonixcoder> sarnold:hmm yes.. bit strange.. I will try to check if old image and fresh install have same settings in /etc/apt folder
[05:19] <thomedy> okay.. sudo apt-get install php5-fpm is not processing the triggeres
[05:20] <thomedy> i can man it but i cant finish the apt-get
[05:38] <neonixcoder> sarnold: I just wondering how frequent linux write data to disk?
[05:39] <sarnold> neonixcoder: that's quite complicated :) it'll write immediately when programs issue fsync or fdatasync calls; apt/dpkg do this extensively
[05:40] <neonixcoder> immediately means less then a second?
[05:40] <neonixcoder> bcz I just want to check logs which are written when upgrading my OS which is resulting me in kernel panic..
[05:40] <sarnold> yeah; it'l suspend the program execution until the writes have finished
[05:41] <sarnold> neonixcoder: the fatrace program can do that
[05:41] <sarnold> for an upgrade it'll be an amazing amount of output..
[05:42] <neonixcoder> let me check that..
[07:36] <murcha> when i run cron to mv files to mounted backup partition i get error: sudo: no tty present and no askpass program specified
[07:37] <sarnold> why are you tryiung to use sudo in cron? that won't go..
[07:41] <murcha> sarnold: thanks, i  tried to mv files to backup partition but it required authentication.
[08:23] <fcefan> murcha: See first fix here https://www.shell-tips.com/2014/09/08/sudo-sorry-you-must-have-a-tty-to-run-sudo/
[08:24] <murcha> fcefan: thanks
[09:10] <DenBeiren> hi all,.. i'm trying to set up an rsync, but the transferspeed is way too slow
[09:10] <DenBeiren> i'm getting 10MB between 2 dualGB nic machines
[09:10] <DenBeiren> configged with LAG on the GB switch
[09:11] <DenBeiren> the copy is local, so encryption is not really needed
[09:11] <DenBeiren> any ideas?
[09:16] <lordievader> Good morning.
[09:19] <DenBeiren> hey lordie
[09:19] <lordievader> Hey DenBeiren, how are you?
[09:19] <DenBeiren> gd gd
[09:19] <DenBeiren> maybe you can help out with my "issue" here above?
[09:21] <lordievader> Is that ram -> ram?
[09:27] <DenBeiren> ?
[09:29] <lordievader> !pm | DenBeiren
[09:29] <DenBeiren> i don't know if everybody is going to benefit from dutch ;-)
[09:30] <lordievader> Ask the question in english.
[09:31] <DenBeiren> i did :-)
[09:31] <DenBeiren> just before you entered ;-)
[09:31] <lordievader> DenBeiren: Yes, and I asked: Is that ram -> ram?
[09:37] <DenBeiren> it's a synonogy share => a temp ubuntu share (to reconfig the syno)
[09:38] <lordievader> What I am trying to rule out is external factors like disks.
[09:38] <DenBeiren> when copying from a windows client to the temp samba i get 66 - 80 MB
[09:39] <DenBeiren> the disks in the syno are brandnew
[09:41] <murcha> is there any service to restart to effect changes in visudo
[09:43] <lordievader> DenBeiren: Do you have root access or ssh access on the synology?
[09:43] <DenBeiren> yes, the rsync is running,.. only it's capping @ 10/11 MB
[09:44] <DenBeiren> evy now and again i see it peaking to 24 - 66 - 30
[09:44] <DenBeiren> but stabilizing @ 10
[09:45] <DenBeiren> command used is the following:
[09:45] <lordievader> I'll take that as a yes I have ssh access. Run a dd over ssh towards the synology's /dev/null
[09:45] <DenBeiren> sudo rsync -avhzP admin@192.168.6.9:/volume1/Data /samba/allaccess/
[09:47] <lordievader> murcha: The sudoers file is read everytime when sudo is run, for as far as I know.
[09:48] <DenBeiren> lordievader: just got a call,.. need to go,.. get back to this later,.. TIA
[09:49] <murcha> lordievader: when i change settings in visudo to allow a user and a script to run w/o sudo from cron, i get the same permission denied error
[09:50] <lordievader> Without sudo?
[09:50] <lordievader> You mean you allow it without a password? You still need sudo though.
[09:52] <murcha> yes when i run a script from cron automatically i get this error: sudo: no tty present and no askpass program specified
[09:52] <lordievader> Could you pastebin your sudoers file?
[09:52] <murcha> sure
[09:54] <murcha> lordievader: here is the configuration: http://pastebin.com/0BPJ0xrC
[09:56] <lordievader> It's about the classi-backup script?
[09:58] <murcha> lordievader: yes
[09:58] <jerto> Murcha, are you trying to invoke sudo in a cron ?
[09:59] <lordievader> murcha: As what user are you invoking the script?
[09:59] <murcha> jerto: i want to run automatically the script through cron....but i get permission denied error
[10:00] <murcha> lordievader: office
[10:00] <lordievader> Why not as root?
[10:00] <lordievader> I suppose that the user office is in the group office?
[10:00] <murcha> yes
[10:04] <murcha> lordievader: i tried root user, again i get permisison denied error
[10:05] <lordievader> Now that is interesting. Do you get the same when you run the script as root?
[10:06] <murcha> lordievader: no not at all, only i get when i try the script from cron. from terminal it is all ok.
[10:07] <lordievader> Hmm, would it be environment variables. Could you pastebin the script?
[10:12] <murcha> lordievader: here is the script a simple mv: http://pastebin.com/ShAdLwhi
[10:15] <lordievader> You are not specifiying an interpreter?
[10:17] <murcha> lordievader: oh it is here at the top #!/bin/bash
[10:18] <lordievader> Ah, ok. Does it have execute permissions?
[10:18] <murcha> lordievader: yes 777
[10:22] <lordievader> Hmm, odd.
[10:22] <lordievader> Do you have another user in the group office?
[10:24] <murcha> lordievader: i should check
[10:25] <murcha> lordievader: yea there is www-data
[10:25] <lordievader> Can that user run the script correctly?
[10:30] <murcha> no it does not run the script
[10:31] <murcha> lordievader: ^
[10:35] <lordievader> Does not run the script, how?
[10:37] <murcha> i tried to run the script after login www-data user, but i get not found error
[10:39] <lordievader> The path to the script is correct? Or is mv saying that.
[10:40] <murcha> lordievader: the path is correct
[10:43] <murcha> lordievader: i tried to run the script like sudo bash path/to/script it is running fine
[10:43] <murcha> ^ from www-data user
[10:44] <lordievader> Okay, so that works...
[10:56] <murcha> lordievader: thanks! finally worked after creating the script under root user.
[10:56] <lordievader> Still odd...
[10:57] <lordievader> But okay, glad it works :)
[10:57] <murcha> :)
[12:13] <_ruben> is there a way to have grub operational through both console and serial?
[13:30] <jamespage> mfisch, hey - so https://bugs.launchpad.net/ubuntu/+source/openvswitch/+bug/1470120 covers the 2.3.2 update for ovs
[13:30] <jamespage> took me a while to get it into wily due to some changes in behaviour in our testing; just working the SRU cogs now
[13:31] <jamespage> med_, ^^
[13:35] <med_> mornign
[13:35] <med_> thanks jamespage
[13:37] <jamespage> med_, np - sorry for the lag
[14:36] <Kully3xf> how much ram does tar use
[14:36] <Kully3xf> is it more cpu or ram
[14:36] <Kully3xf> can I throttle it's ram usage?
[14:38] <patdk-wk> can't imagine it uses either
[14:38] <patdk-wk> unless you enable some kind of compression option
[14:40] <Kully3xf> tar -zxcf so gunzip
[14:42] <Kully3xf> -zcvf
[14:42] <Kully3xf> friday
[14:44] <Kully3xf> in case anyone was wondering it is very low memory and cpu intesive.
[14:50] <pmatulis> use a monitoring utility to answer your question
[14:51] <pmatulis> Kully3xf: ↑
[14:51] <Kully3xf> I figured it out - am not looking to figure it out on the fly, wanted to know before I ran the command
[14:52] <Kully3xf> in case anyone wants to know it's cpu instensive and no ram
[15:08] <dannf> rbasak, mdeslaur : fyi, arges is approving the msyql updates now
[15:11] <teward> with regards to Apache server, when I configure SSL, does the certificate file need to contain the entire chain or just the site's certificate?  And is there a way to serve the CA chain (intermediate cert, root CA cert) without putting it in the main certificate file?
[15:21] <teward> probably a better question: whatever I put in SSLCertificateFile, does that need the entire CA trust chain if I also provide SSLCertificateChainFile in the configuration for a vhost?
[15:28] <rbasak> IIRC it is the entire trust chain.
[15:29] <rbasak> I don't know if there's an alternate way to configure it.
[15:29] <rbasak> No idea about SSLCertificateChainFile
[15:29] <rbasak> Use "openssl s_client" with -verify and experiment ;)
[15:32] <teward> well i think http://serverfault.com/questions/382633/difference-between-sslcertificatefile-and-sslcertificatechainfile answered it
[15:32] <teward> that'll be the first test
[16:05] <TJ-> teward: This is how I configure domains, using symlinks to virtual-host home directories in order to make switching keys+certs not require any changes to the apache config.  https://iam.tj/projects/misc/apache-ssl-config.txt
[16:40] <teward> TJ-: erm... that's not what i was after, but OK
[16:40] <teward> i needed to know what specifically was in the CertificateFile file
[16:40] <teward> I.E.
[16:40] <teward> does it need just the site cert or the entire chain
[16:40] <teward> and i got that answer
[16:41] <teward> in that server there's only one site anyways, so changing the config wouldn't affect others.
[16:47] <TJ-> teward: I thought the example specifies that. The SSLCertificateFile contains *just* the site's certificate, any intermediate Certificates are in the SSLCertificateChainFile, and the root CA can be in that file, or in the usual /etc/ssl/certs/
[16:48] <teward> i couldn't glean that from your example, sorry.
[16:48] <teward> (I'm tired :/)
[16:49] <TJ-> teward:  Hmmm, maybe I'm too familiar with it.  "ssl/certs/iam.tj.pem -> iam.tj.Wosign.solo.2018-06-29.pem"  "solo" is a bare cert with no supporting intermediates
[16:49] <teward> ahh, OK.
[16:49] <teward> TJ-: i come from nginx, not apache, and workplace uses apache on some things :/
[16:49] <teward> kinda inherited things on some of these services >.<
[16:50] <TJ-> teward: I used to have the 'chain' in the domain's /home/ but that was silly since many domains may use the same CA, so the intermediates are now always in  "/etc/ssl/certs/<CA-name>-chain.pem" which is referenced from the SSLCertificateChainFile
[16:51] <TJ-> teward: The remainder of the layout is so I can easily replace certs/keys without making changes to the server config, so it's a non-root operation
[21:55] <IamEld3st> im installing ubuntu 14.04.2 server distribution but i cant get past the iscsi part i dont understand it i have unallocated disk in system and cant select it?
[21:55] <IamEld3st> i found out that i shoud disable raid setting in bios
[21:58] <patdk-lap> what does raid setting have to do with iscsi?
[22:00] <IamEld3st> i dont know i just cant get thour the installation i have one sata drive and while instaling configure iscsi voluems and i cant get past it
[22:00] <IamEld3st> i never seen it before
[22:00] <patdk-lap> well, a sata disk isn't iscsi
[22:00] <patdk-lap> so going into iscsi isn't going to help
[22:00] <IamEld3st> i know
[22:00] <patdk-lap> what options are on your bios?
[22:00] <patdk-lap> first one you should pick is AHCI
[22:00] <patdk-lap> if there is no option, then select RAID
[22:00] <IamEld3st> ok it was set to ide
[22:01] <IamEld3st> should i save it and try it?
[22:01] <patdk-lap> you can attempt ide also
[22:01] <patdk-lap> but I wouldn't want to use it, unless you have to
[22:01] <IamEld3st> ide went to that iscsi thing
[22:01] <IamEld3st> ok i will try to install it
[22:02] <patdk-lap> how?
[22:02] <patdk-lap> it can't see your disk
[22:02] <IamEld3st> yeah but in bios it shows up
[22:02] <patdk-lap> so?
[22:02] <patdk-lap> set it back to AHCI or RAID
[22:02] <IamEld3st> ok
[22:02] <patdk-lap> and figure out why ubuntu can't see it
[22:02] <patdk-lap> something is wrong
[22:03] <IamEld3st> i booted ubuntu desktop and it sees it...
[22:03] <IamEld3st> in live distro
[22:24] <IamEld3st> ok it went good thanks alot man
