| 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 | 13:24 |
| 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? | 13:45 |
| 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 | 13:48 |
| 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 | 13:49 |
| 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 | 13:50 |
| 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 | 13:51 |
| 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 | 13:52 |
| 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 | 13:53 |
| funkenstrahlen | teward: still there? any idea? | 13:59 |
| dft | prudentmav: never used it but it looks interesting. | 14:00 |
| thebwt | funkenstrahlen: unattended upgrades doesn't just run apt-get upgrade on a cron | 14:01 |
| 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 | 14:02 |
| funkenstrahlen | thebwt: yes I know. still I would like to know why my unattednded upgrades does not get run daily | 14:04 |
| 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 | 14:05 |
| dft | I think I would rather | 14:06 |
| dft | ack | 14:06 |
| 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. | 14:07 |
| dft | I think I would rather roll my own wp/vps builder using AWS's api. | 14:10 |
| prudentmav | I use digitalocean and just tired of sysadmin tasks... I'd rather stick to app and front end dev work | 14:14 |
| 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 ? | 14:39 |
| 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. | 14:40 |
| siebjee- | On arch it is possible to update the kernel without down-time | 14:41 |

| 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...) | 18:32 |
| RevertToType | using dhcpcd as the daemon didn't resolve it... dhclient is back on but no clue why it keeps dropping | 18:33 |
| Slugs_ | would you recommend hardware or software RAID? | 18:37 |
| === moonligh- is now known as moonlight | ||
| 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 | 18:43 |
| 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 | 18:44 |
| Slugs_ | RoyK: zfs not ext4? | 18:45 |
| RoyK | !zfs | 18:45 |
| ubottu | For information concerning ZFS and Ubuntu, see: https://wiki.ubuntu.com/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 | 18:45 |
| 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 | 18:46 |
| 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 | 18:47 |
| jelly | how do you even put "4TB drives" and "performance" into the same sentence | 18:48 |
| RoyK | Slugs_: just don't do that | 18:48 |
| 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? | 18:49 |
| 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 | 18:50 |
| 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 | 18:51 |
| 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 | 18:52 |
| 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 | 18:53 |
| 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 | 18:54 |
| 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 | 18:55 |
| 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 | 18:56 |
| 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. | 18:57 |
| 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 | 18:58 |
| 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 | 18:59 |
| 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? | 19:00 |
| 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 | 19:01 |
| 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 | 19:02 |
| 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 | 19:03 |
| 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 | 19:04 |
| 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 | 19:05 |
| 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) | 19:06 |
| 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 ;) | 19:07 |
| sarnold | RoyK: true :) | 19:08 |
| 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... | 19:09 |
| 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 | 19:10 |
| 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 | 19:11 |
| 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 ;) | 19:12 |

| boshhead | sarnold: yeah there's no relevant results on google | 19:32 |
| boshhead | so im in despair :P | 19:32 |

| boshhead | after that ill try replacing grub with elilo or refit | 19:35 |
| RevertToType | sarnold: it lists it as unknown for desired action and not-installed | 19:36 |
| sarnold | boshhead: mkinitramfs(8) suggests /etc/initramfs-tools/modules is the place to put modules | 19:37 |
| boshhead | sarnold: oh right the other file is generated. thank you. | 19:38 |

| 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 | 21:13 |
| jelly | either ^^ or get a drive array that can actually survive more random io | 21:14 |
| jelly | if they're only writing for archival purposes and never reading, it might be doable | 21:16 |
