[06:09] <moneylotion> howdy, hey, anyone have an idea, how i can rsync "from" a read only file system (dvd)
[06:10] <andol> moneylotion: The same way you would rsync from any other file system/path?
[06:11] <moneylotion> "operation not permitted"
[06:12] <moneylotion> a bunch of files have weird used, which cannot be changed
[06:12] <moneylotion> weird users
[06:13] <andol> Any chance that the problem is rather the destination, you are rsync:ing to?
[06:14] <moneylotion> hmmm.... i was copying to a network volume... seems to work when i go to my desktop
[06:40] <lordievader> Good morning.
[07:01] <andol> moneylotion: Well, if it was to a nework volume things makes a lot more sense, given that the mounting user might not have suffecient access to changer ownerships, or that the network filesystem handles users in a different manner.
[07:01] <moneylotion> i guess rsync can ignore permission :)
[07:04] <andol> moneylotion: Yepp, just don't add flags telling rsync to care about permissions, ownerships, etc
[08:19] <moneylotion> any ways I can significantly compress backups?
[08:20] <bearface> depends if the data is significantly compressible
[09:16] <purefan> hello. I found a server who just rebooted and Im trying to find the cause, any advice?
[09:16] <lordievader> purefan: Look in the logs?
[09:17] <purefan> lordievader: I have looked at syslog, auth.log, lastlog, boot.log, apache error.log, apache access.log and wtmp, nothing seems unusual
[09:17] <purefan> lordievader: apache reports getting a sigterm but I cant find what triggered it
[09:18] <lordievader> Does the kernel log show anything?
[09:18] <lordievader> Or does it just stop -> bios.
[09:24] <purefan> its actually missing the entries from around the server reboot
[09:24] <purefan> server reboot happened around 2am, and the earliest entry is from 12:40
[09:25] <purefan> oh hold on
[09:25] <lordievader> purefan: That might indicate a failing disk. Bit difficult to write to a disk if it ain't there anymore.
[09:25] <lordievader> Check smart, I'd say.
[09:26] <purefan> lordievader: the earliest record in the previous kernel log is just for terminating ttys due to Sigterm
[09:27] <lordievader> Hmm, that sounds a bit like an actual reboot.
[09:28] <purefan> and thats weird because afaik no one was even awake at the time
[09:38] <purefan> lordievader: Do you think a faulty HD is a risk in a cloud environment? this server runs on AWS
[09:40] <arcsky_> Im going to install ubuntu on a server with RAID5. should i use the ubuntu installation on the entire drive or just a part of it?
[09:43] <Walex> arcsky_: depends on how you do it and what you want to achieve. Is that hw or sw RAID5? Do you want the system filetrees to be RAID'ed underneath? etc.
[09:45] <Walex> arcsky_: a typical installation profile is to have on each disk a '/' partition, a swap partition and an "other" partition, and if using sw RAID the "other" partitions are those that are RAID5-ed
[09:45] <Walex> arcsky_: traditionally the '/' partitions are RAID1-ed to make it easy to boot from them, and 'swap' does not need to be RAID'ed
[09:46] <Walex> usually at least, some people RAID1 the 'swap' too
[09:52] <lordievader> purefan: No, for a vm it is unlikely.
[09:52] <purefan> lordievader: Thanks
[09:52] <lordievader> I guess Amazon has pretty good monitoring on that.
[09:53] <purefan> lordievader: I think so too, I would expect at least an alert
[09:53] <lordievader> Walex: Raiding swap is usually a good idea. Prevents inconsistent swap when a disk fails.
[09:53] <lordievader> purefan: You won't receive it, their sys-admin team would get that alert.
[09:54] <purefan> lordievader: Ok, but they would let us know if the service was interrupted because of that, right?
[09:56] <lordievader> I don'
[09:56] <lordievader> don't think their service will be interupted by a disk failure.
[09:58] <purefan> lordievader: Yeah I dont think it would either... I need to report this and Im looking at all possible angles, its not a good thing that a server reboots itself without an explanation
[10:01] <Siilwyn> Hi people, if I want to restrict a group of users to only have access to one directory through sftp (Match Group www-data), does it match all users in that group or only if it's their primary group?
[10:19] <arcsky_> Walex: its hw raid
[10:20] <Walex> arcsky_: then hw RAID is transparent to the OS and you need not worry.
[10:21] <linocisco> hi all
[10:21] <linocisco> no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory
[10:39] <mnms_> Guys it is reasonable to give 10GB for swap partition ?
[10:39] <mnms_> I have 5GB of memory
[10:39] <mnms_> it will be a mail server
[10:40] <mnms_> Somewhere I read it shoubd twice of RAM, but it is not too much ?
[10:43] <mybalzitch> its not much space
[10:45] <mnms_> mybalzitch: you mean 10GB for swap its not much space yes ?
[10:45] <mybalzitch> yes
[10:46] <mnms_> mybalzitch: I assigned 8GB finally, can I have problems ?
[10:46] <mybalzitch> if you do, add mroe ram
[10:46] <ogra_> well, mailservers are pretty I/O bound ... if you start swapping you should ASAP get more ram
[10:47] <ogra_> on a busy mail server, swap is rather a safety net than anything else
[10:47] <mnms_> I have 2xSSD disks and I want to put them in software RAID1
[10:47] <mybalzitch> mdadm
[10:54] <mnms_> what initial values you would use for this configuration ?
[10:54] <mnms_> Yes, I dont want to use swap, I think 5GB of memory will be enough for my server and I dont want to hibernate my machine
[10:55] <mnms_> mybalzitch: You are not saying to not use swap at all ?
[10:55] <mnms_> I mean to not create swap partition
[10:56] <mybalzitch> no
[10:56] <mybalzitch> 5-10 gb of swap is plenty, especially if it lives on an SSD
[10:56] <lordievader> Create some swap, as has been said before, as a safety net.
[10:56] <ogra_> create it, but turn down the value for swappiness
[10:57] <mybalzitch> how much mail are you handling anyway
[10:57] <ogra_> so it doesnt get used by default, only for overflowing if required
[10:59] <mnms_> I assigned 8GB
[10:59] <mnms_> lordievader: 1000 mails per day
[11:02]  * ogra_ doubts you will even use any ram with that, unless all 1000 hit the machine at the same time or some such :)
[11:02] <mnms_> swappiness to 0 ?
[11:03] <ogra_> not 0 ... take 1 or 5 ... just less than the default
[11:03] <mnms_> or 10 like it is on help.ubuntu
[11:03] <mnms_> ogra_: ok
[11:05] <mnms_> so 2GB would be ok for SWAP cause I dont expect to use it all, correct ?
[11:07] <mnms_> this would be enough for my "safety net"
[11:09] <ogra_> right, and worst case you can immediately create a swap file and add it to the swap space in case you really hit an emergency
[11:10] <mnms_> ogra_: btw 2GB of swap is not small, yes ?
[11:10] <ogra_> 2G should really be fine
[11:23] <mnms_> guys could you tell me how I can remove raid device which I created before, is says it is in use
[11:24] <mnms_> when I try to stop I get "Cannot get exclusive access"
[11:24] <mnms_> by mdadm --stop /dev/md0
[11:32] <mnms_> Ok..solved it.
[11:46] <Siilwyn> Just a quick question, can I chroot a sftp user to a non-home directory?
[11:46] <Siilwyn> I got it working with a home directory but for some reason it doesn't work if I change it to /srv/userWebsite
[11:46] <Siilwyn> (and yes root does own srv and 'userWebsite'
[12:19] <mnms_> how do you backup your servers, with dd ?:)
[12:19] <lordievader> Dirvish here.
[12:25] <mnms_> lordievader: thanks
[14:13] <jiku> hey guys..
[14:13] <jiku> having a weird issue here..
[14:14] <jiku> i just did an installation of php5-fpm with apache.
[14:15] <jiku> was all fine until when i need to restart the service php5-fpm with /etc/init.d/php5-fpm or reload php5-fpm i get the error..
[14:15] <jiku> http://pastebin.com/D7QqMAV6
[14:15] <jiku> many such lines like these.
[14:16] <jiku> i have to kill the process with PID 2wice 3rice..
[14:16] <jiku> and then start php5-fpm
[14:16] <jiku> is it a bug or something which is per the design ?
[14:18] <genii> I'm pretty sure it uses Upstart and not sysvinit
[14:22] <jiku> yep it does.. but reload php5-fpm is giving the same erro..
[14:22] <jiku> i believe start, reload, stop --> all are upstart related.
[14:27] <patdk-wk> service php5-fpm restart :)
[14:38] <F1skr> Is it possible to get a ubuntu server root file system like what is available here for the cloudimages: https://cloud-images.ubuntu.com/vivid/current/ I'm looking for something without the cloud-init stuff because it doesn't work if I spawn it in a systemd-nspawn container
[14:38] <catphish> F1skr: personally i just do a quick install from dvd in kvm, then extract the filesystem with guestfish
[14:39] <F1skr> that seems very complicated
[14:40] <F1skr> then I could just get the cloud image and remove the stuff I don't need
[14:40] <catphish> normally reasons for wanting a raw image *are* complicated :)
[14:43] <F1skr> I donøt know, I simply want to spawn a systemd-nspawn container with an ubuntu server instance
[14:44] <ogra_> F1skr, http://cdimage.ubuntu.com/ubuntu-core/trusty/daily/current/ (its a bit more cut down than an actual ubuntu-server though)
[14:45] <catphish> i've never seen those before, awesome
[14:46] <ogra_> dont mix them up with the daily-preinstalled images though ... that is ubuntu snappy core ... nothing you can use OOTB
[14:47] <ogra_> (and i guess the better place would actuallly be http://cdimage.ubuntu.com/ubuntu-core/releases/)
[14:47] <F1skr> what does OOTB stand for? :)
[14:47] <ogra_> out of the box
[14:50] <F1skr> that seems perfect for what I'm doing! do you happen to know the default root password in those images?
[14:50] <ogra_> there is none
[14:50] <ogra_> it isnt set up at all
[14:50] <ogra_> it is pretty much mostly for using chroots
[14:51] <ogra_> the definition for the non..snappy ubuntu core images is: just enough OS to run apt
[14:51] <ogra_> (in a chroot that is)
[14:52] <F1skr> or a container as I'm doing now :)
[14:52] <ogra_> :)
[14:52] <ogra_> note, you might need to copy resolv.conf in place
[14:53] <F1skr> systemd handles that for me :)
[14:57] <F1skr> I also needed something where the network service was disabled (in order to let systemd handle it) this is perfect
[14:57] <F1skr> thanks ogra_ !
[14:59] <ogra_> good luck
[15:26] <oste> i am seeing something strange using nginx, when i change the server root symlink, i get “No input file specified” for a few minutes then the new changes are properly displayed
[15:26] <oste> i am using php fpm with fastcgi - and tried setting SCRIPT_FILENAME to a few different things with no luck
[15:31] <teward> oste: there's a document for that somewhere...
[15:31] <teward> oste: what version of nginx?
[15:31] <teward> and what Ubuntu
[15:31] <oste> nginx/1.4.6
[15:31] <oste> Ubuntu 14.4
[15:32] <oste> wonder if i should upgrade nginx
[15:32] <oste> update*
[15:33] <oste> PHP 5.5.9-1ubuntu4.11
[16:40] <jwitko> Hey guys I have a server where my iscsi connections to my SAN stopped working.  I have identical setups in the same network where the iscsi connection is still just fine to the SAN.  Multipath -ll gives me the error "Error: : Inappropriate ioctl for device"   can anyone help ?
[16:47] <teward> rbasak: i plan to bash my head against nginx today/tomorrow, but FeatureFreeze is in, and nginx merging will have new features, do you just want me to wait to X series?
[16:49] <rbasak> teward: I can't approve a feature freeze exception if that's what you're asking?
[16:49] <teward> rbasak: no, i'm asking if it's worth it - there's 3 new features in ntinx 1.9.4
[16:49] <teward> i know you can't approve ;P
[16:49] <rbasak> Hmm
[16:49] <teward> substantial bugfixes though
[16:49] <teward> http://nginx.org/en/CHANGES
[16:50] <teward> it'll be available in Debian tomorrow (uploaded only today, not sure if it's built there yet :P)
[16:50] <rbasak> I'm not sure if I had considered Wily feature freeze when we talked about plans for 1.9
[16:50] <teward> i don't think we had, but given FeatureFreeze has passed I'm OK leaving it alone
[16:50] <teward> and saying "Wily people: use the ppa not the repos, we aren't updating because freeze"
[16:50] <rbasak> Yeah I think you'll have to leave it alone, unless you want to do the work backporting bugfixes from upstream hg
[16:51] <teward> (the ppa gets a resync with debian tomorrow xD)
[16:51] <teward> heheh, yeah, no thanks
[16:51] <rbasak> OK.
[16:51] <rbasak> I'm happy for you to leave Wily nginx alone then and focus on the PPA.
[16:51] <teward> wheee rmadison lag
[16:52] <teward> that's the general idea now
[16:52] <teward> since college started back up and all :)
[16:54] <teward> rbasak: PPAs get updated either way, so long as Debian's version builds, I just 'borrow' the package from there :P
[16:54] <rbasak> Sounds good
[16:55] <catphish> is there something i can append to the installer kernel / initrd to give me a root shell?
[16:55] <catphish> init=/bin/bash doesn't work because there doesn't seem to be a /bin/bash in the initrd
[17:02] <rmc3> Haven't been able to find an answer in the documentation about this: I see that the Ubuntu installer supports using Anaconda-style kickstarts. Is the kssendmac kernel parameter supported for sending the MAC of the interface that's in use to the server providing the kickstart as a parameter?
[17:06] <sarnold> catphish: /bin/sh ought to be a symlink to /bin/dash
[17:06] <catphish> sarnold: thanks, i just actually just this second tried that and it worked :)
[17:06] <sarnold> \o/
[17:07] <catphish> is there a way to run the disk detection procedure from there?
[17:07] <sarnold> "disk detection procedure"?
[17:07] <sarnold> do you mean udevadm trigger or whatever that is?
[17:08] <catphish> the installer does something that loads modules for detected hardware
[17:08] <catphish> i just want to load the modules for my raid array so i can mount something
[17:10] <catphish> i can't run the normal recovery, because its network detection routine breaks my IPMI connection :)
[17:10] <catphish> i suppose a simpler question is: where are the .ko files in the installer?
[17:15] <jwitko> Hey guys I have a server where my iscsi connections to my SAN stopped working.  I have identical setups in the same network where the iscsi connection is still just fine to the SAN.  Multipath -ll gives me the error "Error: : Inappropriate ioctl for device"   can anyone help me trouble-shoot iscsi issues?
[17:15] <jwitko> doing a scan results in the error "no session found"
[17:57] <md50> Does anyone know if there is an ubuntu server installer that includes the sfc (Solarflare) nic drivers?  I tried 15.10 and 14.04.3, but no luck.
[18:01] <md50> only mention of sfc I saw was this bug, but I'm not sure if this was iso or pxe specific.  I tried the isos https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1481490
[18:57] <sarnold> md50: how are you determining if the driver is supported?
[18:57] <sarnold> md50: 'apt-file search sfc.ko' on my 14.04 LTS system shows kernel modules for it for both the 3.13 and the 3.16 based kernel lines
[19:02] <md50> The daily iso builds of the installer don't recognize the cards, and sfc.ko doesn't appear to be on the media.  However, after installing without a network, the kernel that boots contains the sfc module.  So it's a crappy installer, but things eventually work
[19:03] <md50> I won't be able to mass install anything automatically without the driver (e.g. pxe install) but I can hack around it for now
[19:13] <TJ-> if you're doing PXE based installs you can slipstream the driver into the initrd that is served to the host via TFTP
[19:19] <md50> yeah, I guess I'll have to add it as part of my PXE boot, but I was hoping it would just work.
[19:36] <TJ-> md50: I usually have 2 PXE entries per ISO... 1 standard and one unpacked on the server file-system so it can be customised easily
[22:05] <eatingthenight> im on ubuntu server 14.04. When i type hostname i get the hostname as expected. When i type hostname --help it shows all the flags. One of them being -i to get the IP address. when i type hostname -i it says name or service unknown.
[22:06] <eatingthenight> anyone ever ran into this? it's driving me crazy. It seems to work on ubuntu 14.04 02 but not on the original 14.04 release/
[22:06] <eatingthenight> I can't find any bugs about it as well.
[22:06] <eatingthenight> But i have tested it on multiple servers all with the same results.
[22:06] <capricorn_one> your RR in DNS is missing
[22:07] <eatingthenight> sorry what is RR? capricorn_one
[22:07] <capricorn_one> Reverse Record
[22:07] <capricorn_one> man apge says
[22:07] <capricorn_one>        -i, --ip-address
[22:07] <capricorn_one>               Display the network address(es) of the host name. Note that this works only if the host name can be resolved. Avoid  using
[22:07] <capricorn_one>               this option; use hostname --all-ip-addresses instead.
[22:08] <eatingthenight> o i see. I was using -i because -I adds an extra space at the end of the output
[22:08] <eatingthenight> i guess i'll just strip it out since that is more reliable
[22:08] <eatingthenight> capricorn_one: Thank you very much
[22:09] <capricorn_one> when in doubt use man pages
[22:10] <eatingthenight> capricorn_one: Yeah i need to get better about that one.
[22:43] <sarnold> eatingthenight: why are you looking for the local IP? perhaps there's a better way to do what you're doing
