[13:24] <megagigawatt> Hi there, I was wondering if anyone could help me with a samba/acl issue i am having please, I have made a post on the forums here http://ubuntuforums.org/showthread.php?t=2294351 which is probably easier to understand than me trying to type it out here, thanks in advance
[13:45] <funkenstrahlen> Hey, I need some help setting up unattended upgrades on my ubuntu server. I installed and configured it, but it does not get run automatically somehow...
[13:45] <funkenstrahlen> I used this infopage to set it up https://help.ubuntu.com/community/AutomaticSecurityUpdates
[13:45] <teward> funkenstrahlen: what makes you say it's not run?
[13:48] <funkenstrahlen> teward: I checked back after 14 days. could not find any logs in /var/log/unattended-upgrades. Then I ran apt-get upgrade manually. some updates where found. so I ran unattended upgrades manually and a log was created.
[13:48] <funkenstrahlen> teward: So this is evidence for me it did not run at all
[13:49] <funkenstrahlen> my apt.conf.d looks like this: https://gist.github.com/funkenstrahlen/2153d78dc2a786bb9c4d
[13:49] <funkenstrahlen> so periodica intervald of each day is set
[13:50] <funkenstrahlen> I *think* I might now the problem, but do not know enough about how unattended upgrades work
[13:50] <funkenstrahlen> I found a script in /etc/cron.daily/apt.disabled
[13:51] <teward> funkenstrahlen: OS?
[13:51] <funkenstrahlen> I assume that by default this apt script runs the unattended upgrades?
[13:51] <teward> or rather the version
[13:51] <funkenstrahlen> teward: ubuntu server 14.04 lts
[13:52] <funkenstrahlen> I thought maybe the *.disabled blocks it from getting run?
[13:52] <funkenstrahlen> but why is it .disabled? there is no word of that in any tutorials
[13:53] <funkenstrahlen> and because it works fine when I run unattended upgrades manually, I do not think there is a config file error. Its just not getting called at all
[13:53] <prudentmav> any thoughts on the use of serverpilot? If any of you use it
[13:59] <funkenstrahlen> teward: still there? any idea?
[14:00] <dft> prudentmav: never used it but it looks interesting.
[14:01] <thebwt> funkenstrahlen: unattended upgrades doesn't just run apt-get upgrade on a cron
[14:02] <prudentmav> dft I used it on a development environment and it did save a lot of time but just hesitant to use in a production environment
[14:02] <thebwt> it picks specific package types
[14:04] <funkenstrahlen> thebwt: yes I know. still I would like to know why my unattednded upgrades does not get run daily
[14:05] <dft> prudentmav: I hear you.  If serverpilot goes away, what will take to unplug your VPS's from it and take manual control of your wp sites
[14:05] <prudentmav> yeah that is the big unanswered question for me
[14:06] <dft> I think I would rather
[14:06] <dft> ack
[14:07] <dft> typing spasm
[14:07] <dft> rather use aws and bootstrapping if I was in the business of building wp sites for all sorts of clients.
[14:10] <dft> I think I would rather roll my own wp/vps builder using AWS's api.
[14:14] <prudentmav> I use digitalocean and just tired of sysadmin tasks... I'd rather stick to app and front end dev work
[14:39] <siebjee-> Hi Guys, I'm running ubuntu server 15.10 with 4.1.0.3-generic kernel. And updated to 4.2.0-7generic. But it has not been live updated. I thought this was new in 4.0 kernel ? Any info on this ?
[14:39] <jpds> siebjee-: I imagine the tooling with apt isn't yet in place
[14:39] <siebjee-> jpds: is there a way to force this anyway ?
[14:40] <siebjee-> I'd realy like to see this happening! *_*
[14:40] <jpds> (Also, I don't think it's a good idea to run a non-LTS release on a server)
[14:40] <siebjee-> Its my private server, so don't really care about LTS on there or not :)
[14:40] <siebjee-> On production servers i would care about LTS
[14:40] <Seveas> siebjee-: there is no such thing as live kernel updates.
[14:41] <siebjee-> On arch it is possible to update the kernel without down-time
[14:53] <revolve> is there any way of getting dlm-pcmk on 12.04?
[14:55] <rbasak> frediz: from #ubuntu-devel:
[14:55] <rbasak> 15:54 <stgraber> rbasak: I'm happy with ginger, for kimchi, you're missing a debian/copyright entry for  ui/pages/help/gen-index.py which is LGPLv2.1+ and not Apache2 as debian/copyright declares
[14:56] <jpds> rbasak: https://launchpad.net/ubuntu/precise/amd64/dlm-pcmk
[14:57] <rbasak> jpds: ?
[14:57] <jpds> rbasak: Err, that was for revolve.
[14:57] <rbasak> np
[14:58] <revolve> jpds: right, I'm on trusty though
[14:58] <revolve> can I get those sources?
[14:59] <jpds> revolve: You said 12.04
[14:59] <revolve> right
[14:59] <revolve> ah 14.04 sorry
[18:32] <RevertToType> so... it's definitely something related to the dhcp lease...
[18:32] <RevertToType> seems client side not server side
[18:32] <RevertToType> after about 30 minutes it drops.... running dhclient in terminal kicks it back in (don't even need to release the old lease...)
[18:33] <RevertToType> using dhcpcd as the daemon didn't resolve it... dhclient is back on but no clue why it keeps dropping
[18:37] <Slugs_> would you recommend hardware or software RAID?
[18:43] <RoyK> Slugs_: I'd recommend sw raid
[18:43] <RoyK> Slugs_: but it all depends the use of it
[18:43] <Slugs_> yeah alot of people are recommending sw
[18:44] <RoyK> Slugs_: hwraid can be fine on the boot medium, since it outrules problems with boot sectors
[18:44] <tonyyarusso> I usually go for SW too, so I don't have to worry about finding a matching controller if it dies.
[18:44] <RoyK> Slugs_: sw raid (or zfs if you're doing the planning well) is what I'd recommend for data
[18:45] <Slugs_> RoyK: zfs not ext4?
[18:45] <RoyK> !zfs
[18:45] <RoyK> Slugs_: zfs is something like mdadm+lvm+checksumming
[18:45] <Slugs_> wow
[18:45] <RoyK> Slugs_: it's very secure, checksumming all over, but it's not very flexible
[18:46] <RoyK> Slugs_: I'm using zfs in production, also on my home server, but I'm planning to go back to mdadm, for various reasons
[18:47] <Slugs_> i see
[18:47] <RoyK> Slugs_: if you have a machine with ECC RAM and you don't want to add new disks to the raidset, use ZFS - otherwise, I'd suggest mdadm raid
[18:47] <Slugs_> well I’m trying to simplly setup 4, 4TB drives in a RAID0 config for performance
[18:48] <jelly> how do you even put "4TB drives" and "performance" into the same sentence
[18:48] <RoyK> Slugs_: just don't do that
[18:49] <jelly> are there 15krpm 4TB drives now?
[18:49] <RoyK> Slugs_: what sort of performance? iops or sequencial?
[18:49] <RoyK> jelly: no
[18:49] <jrwren> no btrfs love?
[18:50] <Slugs_> oh i see, the drives are too big for ‘performance’ im assuming your all saying
[18:50] <RoyK> Slugs_: a single 4TB drive can do something like 200MB/s sequencially, far less with seeks, very far less
[18:50] <RoyK> Slugs_: it all depends on how you look at performance
[18:50] <Slugs_> im trying to write about 80 mbps
[18:50] <Slugs_> constantly
[18:50] <RoyK> Slugs_: 4TB drives spin at 7200rpm, meaning they may do 120iops
[18:51] <patdk-wk> heh, that is a lot of iops for 7.2k rpm
[18:51] <RoyK> Slugs_: a single drive can do that - a raid5 with four drives can certainly do that unless the CPU is something 10+ years old
[18:51] <RoyK> patdk-wk: 'may' do - usually around 80
[18:52] <Slugs_> i thoguht raid0 was better then raid5 since its only stipped
[18:52] <RoyK> Slugs_: striped, not stripped
[18:52] <Slugs_> sorry yes
[18:52] <RoyK> Slugs_: raid5 on 3 drives has about the same speed as raid0 on 4 drives
[18:52] <RoyK> Slugs_: for reads
[18:53] <RoyK> Slugs_: a wee bit less for writes
[18:53] <Slugs_> i need writes more then reads in this setup
[18:53] <Kalimer0> my server hangs during the restart via cron . it fails to shutdown syslog-ng . any ideas?
[18:53] <RoyK> Slugs_: and you'll be a sorry bastard if using raid0 with your data and a drive fucks up, and it will, beleive me on that
[18:53] <RoyK> Slugs_: is the data important?
[18:53] <ikonia> RoyK: come on with the language !
[18:53] <Slugs_> RoyK: understood
[18:54] <RoyK> Slugs_: if the data isn't important, use raid0
[18:54] <RoyK> Slugs_: if you need massive writes and the data is important, use raid1+0
[18:54] <patdk-wk> you mean, if uptime isn't important
[18:54] <RoyK> patdk-wk: or data
[18:54] <patdk-wk> why? backups cover important data, not raid
[18:55] <patdk-wk> raid covers uptime
[18:55] <ikonia> design to your requirements
[18:55] <RoyK> patdk-wk: well, if you have a truckload of writing, backups won't be enough to get the important data if a drive is lost 23 hours after last backup in a raid0 setup
[18:55] <Slugs_> so just to be clear raid 1+0 is good of data *is* important as well
[18:56] <Slugs_> *if*
[18:56] <Slugs_> s/of/if
[18:56] <patdk-wk> that is a backup failure then, backup every 5min, I do
[18:56] <RoyK> Slugs_: with 1+0 you'll get the best of both worlds, good iops and good sequencial i/o, but you'll have to get a lot of drives
[18:57] <Slugs_> 4 not enough/
[18:57] <Slugs_> ?
[18:57] <patdk-wk> some servers I even have on continuous backup, once it's done, it starts again.
[18:58] <RoyK> Slugs_: what are your requirements? what sort of backup do you use? etc?
[18:58] <patdk-wk> raid6 is generally better than raid10 with limited disks
[18:58] <patdk-wk> but it does have iop issues
[18:58] <RoyK> Slugs_: are you on 10Gbps or just gigabit?
[18:58] <patdk-wk> but better for protection
[18:58] <RoyK> patdk-wk: obviously true
[18:58] <Slugs_> RoyK: I don’t care about backing it up, im using 1 gb (network)
[18:58] <patdk-wk> raid10 has the issue if one disk breaks, you depending on the other disk to be fine, normally this is the case, and not an issue
[18:59] <RoyK> Slugs_: what sort of i/o is this? are you just dumping data to this?
[18:59] <Slugs_> yes im wriring multicast video to disk
[19:00] <Slugs_> 80 mpbs
[19:00] <RoyK> then use raid[56]
[19:00] <RoyK> it's good for sequencial stuff
[19:00] <RoyK> 80Mbps is rather a lot
[19:00] <RoyK> use mdraid with a large chunk size and use raid-5 or better raid-6
[19:00] <Slugs_> the bottleneck would be my drives?
[19:01] <Slugs_> 7200 rpm
[19:01] <RoyK> with a large chunk size, the drives should do 100MB/s each
[19:01] <RoyK> or more
[19:01] <Slugs_> and i can configure this with mdraid?
[19:01] <RoyK> man mdadm ;)
[19:01] <Slugs_> ok
[19:02] <Slugs_> RoyK: Thank you for the advice
[19:02] <RoyK> Slugs_: what is this - cctv stuff?
[19:02] <Slugs_> and guidance
[19:02] <Slugs_> no, NPVR
[19:02] <Slugs_> network PVR
[19:02] <Slugs_> for off-air channels
[19:03] <Slugs_> recording live tv
[19:03] <RoyK> same thing, really
[19:03] <Slugs_> sure, just thought you wanted to know ;)
[19:03] <RoyK> Slugs_: just use a large chunk size on that raid
[19:03] <Slugs_> ok
[19:03] <RoyK> Slugs_: and use at least raid-5
[19:03] <Slugs_> ok
[19:03] <Slugs_> Thank you again
[19:04] <RoyK> Slugs_: your boss will hate you if the raid goes down and the data is lost
[19:04] <Slugs_> well i already hate him, so we will be even
[19:04] <RoyK> Slugs_: also, better use a lot of spindles rather than a few large ones
[19:04] <Slugs_> yeah, more drives the better
[19:04] <RoyK> Slugs_: the most important is the chunk size - 1MB minimum
[19:04] <Slugs_> it might even make sense to add more smaller capacity drives
[19:05] <Slugs_> ok
[19:05] <jrwren> how many video streams are you going to record at once?
[19:05] <RoyK> 4MB or 8MB may be practical
[19:06] <Slugs_> im recording 40, 3.5 Mbps streams at once
[19:06] <jrwren> wow! cool. good luck :)
[19:06] <RoyK> Slugs_: and monitor CPU use - it will be used for parity calculation - it should be pretty fast, but at the rate you're mentioning you may need a good CPU (or four)
[19:07] <sarnold> 160 Mbps? not 160MBps?
[19:07] <RoyK> Slugs_: sar/sysstat may be a good friend for long time monitoring, so may munin be
[19:07] <Slugs_> 4 core, Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz
[19:07] <RoyK> sarnold: 160MBps won't work too well over gigabit ;)
[19:08] <sarnold> RoyK: true :)
[19:09] <RoyK> Slugs_: should do well
[19:09] <RoyK> Slugs_: what is the current cpu usage over the last hour?
[19:09] <Slugs_> im not recording anything...
[19:10] <mtl11> Hi. I'm trying to figure out an issue with unmodified cloud images. If I download and launch a 14.04 cloud image on openstack, when I try to update the kernel or otherwise run update-grub it hangs trying to "modprobe btrfs".  Anyone have any idea why it might be doing that?
[19:10] <RoyK> Slugs_: then install sysstat, enable it, install munin-node and perhaps munin if you don't have a munin installation somewhere and make nice graphs to see how it's behaving
[19:10] <Slugs_> awesome thank you
[19:11] <RoyK> Slugs_: there are several other monitoring systems available, but munin is easy to install, so I'd recommend it if you don't have any experience in monitoring
[19:11] <Slugs_> i don’t so thank you
[19:12] <Slugs_> the more i learn the more i realize i don’t know
[19:12] <RoyK> Slugs_: touché
[19:12] <RoyK> Slugs_: that's philosophy ;)
[19:12] <Slugs_> RoyK: Yes ;)
[19:16] <RevertToType> so still thirty minutes even after changing dhclient.conf to send dhcp-lease-time 600;
[19:20] <RoyK> rbanffy_: did you restart dhclient?
[19:21] <RevertToType> restarting it works but i need it to do that automatically
[19:21] <RevertToType> like i shouldn't even have to do that
[19:22] <sarnold> RevertToType: copy aside your dhclient systemd thingy, apt-get purge dhclient, and try out dhcpcd instead. This has just been too much hassle...
[19:26] <boshhead> Hello, I'm trying to install ubuntu 15.04 server, I have also tried 15.10 server and the system gets stuck after "boot-efi.mount". I've typed up the messages I get on bootup: http://paste.ubuntu.com/12428947/
[19:26] <boshhead> Both 15.04 and 15.10 hang on the same message.
[19:28] <RevertToType> sarnold: i basically did that yesterday and dhcpcd didn't seem that good but i'll do a full reboot and try again :(
[19:28] <sarnold> RevertToType: oh. :(
[19:28] <RevertToType> "virtual packages like 'dhcp-client" can't be removed
[19:29] <RevertToType> oi dpkg
[19:29] <RevertToType> dpkg is saying it's not installed
[19:29] <RevertToType> WUHT
[19:30] <RevertToType> update/upgrade time
[19:31] <sarnold> RevertToType: dpkg -l '*dhc*' may show what's really going on..
[19:32]  * RevertToType nods
[19:32] <sarnold> boshhead: dang that's the worst thing to google for, ever.
[19:32] <boshhead> sarnold: yeah there's no relevant results on google
[19:32] <boshhead> so im in despair :P
[19:34] <boshhead> oh wait.. maybe this is it "It sounds like your initramfs doesn't have the needed module for vfat." - im gonna try adding vfat to /etc/modules if it doesn't exist
[19:35] <boshhead> after that ill try replacing grub with elilo or refit
[19:36] <RevertToType> sarnold: it lists it as unknown for desired action and not-installed
[19:37] <sarnold> boshhead: mkinitramfs(8) suggests /etc/initramfs-tools/modules is the place to put modules
[19:38] <boshhead> sarnold: oh right the other file is generated. thank you.
[19:40] <robertj> so is debootstrap for vivid just...broken?
[19:41] <boshhead> rebooting, which me luck :)
[19:55] <netameta> well, i have jenkins set up, Not insde a container. now i am trying to run a job, the job should clone a repo from github, and then run a bash script. , i am not sure how to tell jenkis where to clone the repo to.
[20:01] <ikonia> try #jenkins ?
[20:01] <netameta> Thanks
[20:30] <RevertToType> this is gonna be the death of me... grabbing a second laptop- out of our bin--- starting from scratch... maybe i just left too much of a mess
[20:32] <dmsimard> jamespage: Sorry to poke you, did you guys notice any issues around python-cryptography/python-cffi on liberty packages with services like nova or keystone ?
[21:13] <jelly> Slugs_: you'll eaither need to mux that back to some 1-4 streams to disk, cheap 4TB sata disks are not very likely to be able to work with 40 parallel writers
[21:14] <jelly> either ^^ or get a drive array that can actually survive more random io
[21:16] <jelly> if they're only writing for archival purposes and never reading, it might be doable
[21:19] <jelly> (and if you want users to also watch those saved streams, you're looking at SSDs or ramdrives, two orders of magnitude more expensive solutions)
[21:20] <ratrace> is Ubuntu (15.04) capable of booting from root on multi-disc btrfs? It requires special btrfs device scan support.
[21:21] <ratrace> I'm talking about mounting root, not actually booting, I know /boot can't be btrfs
[21:28] <netameta> How can i create a new user and assign it ssh key ?
[21:29] <netameta> new user is adduser, but how can i assign it neww ssh keys
[21:30] <OerHeks> netameta, login as that user, and follow the guide ? https://help.ubuntu.com/community/SSH/OpenSSH/Keys
[21:31] <netameta> OerHeks, i dont think i can log in with this user
[21:31] <netameta> not before i have ssh keys for it
[21:31] <netameta> ec2 restrict access to only ssh keys
[21:32] <netameta> unless, its possible to create a user from the main user, and then use the new user and follow that guide
[21:32] <OerHeks> netameta, oh, not sure how ec2 works, they should auto make ssh keys when adding an user, logically
[21:33] <netameta> yea i have 1 pair for the main user
[21:33] <netameta> so i can log on their instan
[21:33] <netameta> but i need another user
[21:33] <netameta> Is it possible to create a user and then "mount" it ?
