MACscr | why does it seem like sometimes after kernel/grub updates that the default kernel selection no longer works and i have to press enter? sucks for remote systems | 00:09 |
---|---|---|
TJ- | That happens if the GRUB 'recordfail' flag is set due to an unclean OS shutdown | 00:25 |
MACscr | TJ-: thanks, i will check | 00:25 |
qman__ | You can disable that functionality in he grub configuration | 00:26 |
qman__ | It's a relatively new feature that's a pain in the rear | 00:27 |
TJ- | recordfail has been around many years :) | 00:28 |
MACscr | odd, all the suggestions im finding are old and seem like hacks | 00:35 |

roseysdad | i need help | 01:49 |
adun153 | roseysdad: Just ask, people will answer if they are active and have a helpful answer. | 01:51 |
ksx4system | does it make sense to run mail server on VPS with just 256M of ram? 14.04 LTS 32-bit, postfix+dovecot+something to filter spam | 02:40 |
sarnold | maybe if it's ssd backed or osmethinng... | 02:46 |
sarnold | otherwise feels a bit itght | 02:46 |
roseysdad | how can i see what services are running in systemd? | 02:54 |
ksx4system | sarnold, pure SSD | 03:02 |
ksx4system | and super low volume (never over 50 mails a day, 99% of them under 10 kilobytes) | 03:03 |
adun153 | ksx4system: It might work, but I'm still pretty nervous about that, especially if it is to be used for something in production/mission-critical. | 03:05 |
ksx4system | adun153, what exactly is that *insanely* resource hungry? the spam filtering part? | 03:07 |
ksx4system | (of course I'm going to run postfix/dovecot combo operating without SQL database) | 03:08 |
adun153 | Ubuntu has never exactly been a "lean" distro, if you know what I mean. | 03:09 |
adun153 | You can probably run it, but it might have to swap quite a bit, I thin. | 03:09 |
adun153 | *think. | 03:09 |
ksx4system | adun153, if you take some time it can be as light as properly tuned Debian :) | 03:09 |
ksx4system | but Ubuntu has longer support cycles (5 years for LTS) | 03:10 |
ksx4system | what about 512M? would it help? | 03:11 |
adun153 | ksx4system: I'd be a lot more comfortable with 512. | 03:11 |
ksx4system | this is insane | 03:12 |
adun153 | ksx4system: But it seems like you have the time, you can set up the 256 instance, try it out, see if your hypothesis is correct. | 03:12 |
adun153 | You asked us for our opinions, you got it from sarnold and myself. Eventually, it's entirely up to you. :) | 03:13 |
ksx4system | adun153, well I have around 3 months until date I have to move | 03:13 |
ksx4system | so I can do some proper testing :) | 03:13 |
adun153 | Sounds good. | 03:13 |
ksx4system | webmail is not an issue (hardcore tuned lighttpd + minimal php5 + squirrelmail) I think | 03:14 |
ksx4system | this should eat at most 20M | 03:14 |
ksx4system | if not less... | 03:15 |
ksx4system | what about backup MX? do I need a big (256-512M) VPS too? | 03:15 |
adun153 | If just running Postfix, I think 256 should be fine. | 03:18 |
ksx4system | will 128 do? | 03:19 |
ksx4system | (yes, I always try to squeeze stuff as much as possible) | 03:19 |
adun153 | 128? I don't know. Leaning towards "no". | 03:22 |
ksx4system | challenge accepted lol | 03:25 |
adun153 | lol | 03:25 |
adun153 | good luck | 03:25 |
ksx4system | thanks :) | 03:29 |
ksx4system | (I was actually surprised that mail server needs anything over 64M) | 03:29 |

lordievader | Good morning. | 08:16 |
mripguru | hey guys - anyone here successfully install Ubuntu 12.04 or 14.04 (either LTS) successfully on a Dell C6100 blade server? It will just not install - and the installer is quite slow when it does try and work. | 08:51 |
lordievader | mripguru: "It will just not install", do you get errors or something? | 08:52 |
mripguru | lordievader: nope - but, most of the operations, etc. take on average a year and a day -- and when it did install earlier on (another blade in the same cluster) - it would boot to a black screen | 08:53 |
mripguru | so no - it doesn't technically error | 08:54 |
lordievader | mripguru: Hmm, the installer does run? | 08:54 |
mripguru | but it doesn't work - either. | 08:54 |
mripguru | lordievader: it looks like it's going to install successfully - but, usually just hangs up for awhile | 08:55 |
mripguru | like the partitioning stage | 08:55 |
lordievader | From the limited shell the installer gives you I'd test the disks and the overall performance of the machine. | 08:55 |
mripguru | can take 20-30 min | 08:55 |
lordievader | Since what you describe make me think that there is some trouble accessing the disks. | 08:56 |
mripguru | bad disks? | 08:58 |
lordievader | mripguru: Could be, like I said, test them ;) | 08:58 |
mripguru | yup - let's see what another node does | 09:05 |
lordievader | ? Why? | 09:06 |
lordievader | Test where the problem lies not somewhere else. | 09:06 |
kichko | Hey does anybody here tried the openstack-installer on ubuntu server...I'm behind a proxy and the creating of the container works but the initialization of the container fails...I'm 100% sure that there has to be some additional proxy-setting that I might have missed | 09:09 |
mripguru | lordievader: I want to see if another node has the same behavior | 09:10 |
mripguru | for comparison. | 09:10 |
kichko | the command.log says error.py:35] showing error view for: Top-level container OS did not initialize correctly. | 09:11 |
kichko | while initializing it seems like that the deb repositories are not available but I check them manually they are up. | 09:13 |
mripguru | lordievader: I think you may be onto something - but, I don't think it's the actual disks. | 09:44 |
lordievader | mripguru: What did you find? | 09:44 |
mripguru | lordievader: just for the hell of it - I'm installing XenServer - which does not support FakeRAID | 09:45 |
mripguru | and it seems to be installing just fine. | 09:45 |
lordievader | mripguru: Why not start with some basic dd tests to check the disk speeds? | 09:45 |
mripguru | so looks like the issue may actually be in the FakeRAID | 09:45 |
mripguru | lordievader: can do that - but, I know the disks are fine (more or less) | 09:46 |
lordievader | Oh that can be, but perhaps there is something blocking Ubuntu from achieving the full disk speed (then you know why it is so slow ;) ) | 09:46 |
mripguru | lordievader: sounds like I should try turning off the FakeRAID and just building a true software RAID setup? | 09:48 |
mripguru | (after running some disk tests) | 09:49 |
lordievader | That is not what I am saying, I am saying you need to form a hypothesis then gather some data to see if it is correct. | 09:49 |
lordievader | Only then you can think of a solution. | 09:49 |
lordievader | Just doing things without reason is rather futile. | 09:50 |
mripguru | lordievader: agreed | 09:51 |
mripguru | lordievader: at this point - all roads lead either to the FakeRAID or the disks themselves - need to isolate each | 09:55 |
lordievader | mripguru: Exactly ;) | 09:55 |

mripguru | lordievader: I suspect part of the slowness may actually be the fact that I'm trying to install over IPMI/DRAC | 10:42 |
lordievader | SOL IPMI? | 10:43 |
mripguru | lordievader: no - some bastardized version of Supermicro IPMI | 10:43 |

dannysmc95 | Hello, I am having some trouble with mysql? I can't seem to connect to it from my client on my computer, I use the IP and the 3306 port and it just errors, it says communication link failure (I am using DBBeaver), any help would be awesome, it says in the /var/log/mysql/error.log that it is ready to be connected to... but nothing? its enabled in my firewall so what can I do? | 10:47 |
bekks | dannysmc95: Is your mysql server listening on a port or a socket? | 10:48 |
dannysmc95 | bekks how would I find out? | 10:48 |
bekks | By looking at your config file. | 10:49 |
dannysmc95 | [mysqld] ? | 10:49 |
dannysmc95 | bekks: it says socket = /var.run.mysqld.sock and port = 3306 under that | 10:50 |
bekks | dannysmc95: But there is no IP address configured to listen on? | 10:50 |
dannysmc95 | It uses bind-address = 127.0.0.1 | 10:51 |
bekks | So it is listening on localhost Port 3306 | 10:52 |
bekks | Is 127.0.0.1 the IP you are trying to connect to? | 10:52 |
dannysmc95 | No I am external so using the servers IP | 10:52 |
bekks | Your mysql server isnt listening on that IP. | 10:52 |
dannysmc95 | Okay but if I remove that IP would it not stop localhost access? | 10:53 |
dannysmc95 | ? | 10:54 |
bekks | 0.0.0.0 will make it listen on all address, a.b.c.d (your external IP) will make it listen on that IP only, 127.0.0.1 makes it listen on localhost only. | 10:55 |
dannysmc95 | Okay so I should set bind-address to 0.0.0.0 | 10:56 |
bekks | Only if you need to access it from localhost, too. | 10:56 |
dannysmc95 | Yeah I would do, so I can use php? | 10:57 |
bekks | you can use php using the socket, too. | 10:57 |
bekks | But 0.0.0.0 should be fine. | 10:58 |
dannysmc95 | bekks: access denied? | 10:58 |
bekks | dannysmc95: Is that a question? | 10:58 |
dannysmc95 | bekks: yeah its the correct user and password...? | 10:59 |
bekks | Did you restart the mysql server after changing the config? | 10:59 |
dannysmc95 | yeah | 10:59 |
bekks | Then your credentials arent correct. | 10:59 |
dannysmc95 | It works via CLI | 10:59 |
dannysmc95 | same password and same user, works my doing mysql -u <user> -p and then typing password? | 11:00 |
bekks | Nope. | 11:00 |
bekks | mysql -u user -p password -h host | 11:00 |
dannysmc95 | Eh? I am saying when connected to SSH to my server it works by doing the command above and works fine? but when I am trying to connect from a client on my pc here it doesn;t? do I need to allow the host? | 11:01 |
lordievader | Sounds like a firewall is doing its job. You don't want you sql server exposed to the internet. | 11:03 |
bekks | So if it works on your host, thats fine. Now you need to configure your server to allow connections from your client. | 11:03 |
dannysmc95 | bekks: how exactly do I do that? I am very new to having a server? | 11:04 |
bekks | dannysmc95: I dont know how/what you did on your server to inhibit connections from your client. | 11:05 |
dannysmc95 | bekks: neither do I... | 11:05 |
dannysmc95 | I did the grant all on command in mysql via ssh but it says 0 rows affected? | 11:07 |
dannysmc95 | GOT IT | 11:08 |
dannysmc95 | Thanks for the walkthrough, I needed to permit my host name | 11:09 |
dannysmc95 | allow* | 11:09 |
Mooslapke | Anyone can help me with git? I am trying to let other people connect to my server securely | 11:16 |
Mooslapke | I think best with keys? | 11:16 |

thresh | hi. anyone using packer to provision ubuntu 15.10 machines? | 13:38 |
RoyK | are you using 15.10 on servers? | 13:39 |
thresh | I'm trying to provision a server machine, yes. | 13:39 |
RoyK | I hope this is not for production - it was released yesterday... | 13:40 |
thresh | indeed :-) | 13:40 |
RoyK | and isn't LTS | 13:40 |
RoyK | and ... | 13:40 |
RoyK | oh well | 13:40 |
thresh | This is for a buildbot / build farm. We're providing nginx.org packages built for different OSes. | 13:40 |

teward|live | thresh: let me guess - the nginx.org repo? ;) | 13:41 |
thresh | :P | 13:41 |
thresh | yes | 13:41 |
* teward|live whistles nonchalantly then throws the idea of sbuild out there | 13:41 | |
thresh | teward|live: last time I checked it could not build stuff on centos and sles :-) | 13:42 |
teward|live | thresh: no, it can't, i meant specifically for your Ubuntu/Debian builds | 13:42 |
teward|live | thresh: granted, though, if you're doing builds on individual 'machines', even virtual, i | 13:42 |
teward|live | i'm left scratching my head as to why | 13:42 |
teward|live | but that's my opinion :) | 13:43 |
thresh | the idea is to have prebuilt images for all OSes we support and do builds in a clean env every time | 13:43 |
teward|live | (that's what sbuild does *cough cough* | 13:43 |
teward|live | ) | 13:43 |

thresh | uh, looks like whenever I launch ubuntu 15.10 server cd install, providing options in the console UI (clicking escape, escape, enter from main grub UI) with "boot: " gets me back to grub... | 14:39 |
thresh | nice, and 15.04 does exactly the right thing when I type in "/install/vmlinuz auto initrd=/install/initrd.gz" -- it tries to boot up the installer.. | 14:45 |
thresh | can anyone confirm that? | 14:45 |
thresh | that's using http://releases.ubuntu.com/15.10/ubuntu-15.10-server-amd64.iso | 14:45 |
RoyK | thresh: sounds like grub wasn't installed correctly | 15:09 |
thresh | RoyK: "installed" on a CD you mean? | 15:10 |
thresh | this is when I boot the CD up. | 15:10 |
RoyK | oh | 15:10 |
RoyK | no, haven't seen that | 15:10 |
RoyK | thresh: actually, I don't think I've _ever_ seen that from a cd boot, but then, I've only used linux for 20 years or so ;) | 15:12 |
thresh | well me neither and that's what's happening with 15.10 server isos (both i386 and amd64) | 15:13 |
RoyK | thresh: I'm install 15.10 in a VM as we speak | 15:13 |

jonah_ | hi can anyone please help. I'm trying to setup ubuntu 14.04 with a raid 10 using the ubuntu installer - so far i've just made a right mess of it each attempt! I followed the UrbanPenguin youtube video but he only does raid one and he uses an older version of ubuntu too so the guide just hasn't worked for me | 18:22 |
jonah_ | any help really appreciated. | 18:22 |
jonah_ | got a bootable usb with ubuntu server 14.04.3 on | 18:22 |
jonah_ | and also got a bootable gparted usb | 18:22 |
jonah_ | I'd hoped between the two it would work | 18:22 |
lownin | I'm running ubuntu server 15.04 on my home server. After doing apt-get dist-upgrade, this happens when I try to boot - http://imgur.com/a/20zFG | 18:23 |
lownin | It seems to be failing to boot with Ubuntu Kernel 3.19.0-31 and if I interupt grub during boot and select 3.19.0.15, my system boots just fine without the above errors. Anyone have any ideas where I should even start with this? Thanks! | 18:23 |
sarnold | jonah_: there's some information on the installer's raid stuff here https://help.ubuntu.com/14.04/serverguide/advanced-installation.html | 18:23 |
jonah_ | sarnold: thanks this looks very similar to the youtube I followed. both mention the option of Primary drives being selectable but I had no option for Primary in 14.04... | 18:25 |
jonah_ | sarnold: i'll try follow the guide you've linked and just see if it is any different or works better than the youtube one. I get all the system installed etc but it just fails at the end and can't install grub, also I don't know what path i'm supposed to enter for grub... | 18:26 |
jonah_ | sarnold: the other problem I had when partitioning with the installer live usb is it wouldn't let me set the partitions as 'bootable' when I pressed enter to change it to bootable nothing happens. very weird | 18:27 |
sarnold | lownin: you might try #ubuntu-kernel, or file a bug against the 'linux' package | 18:28 |
sarnold | lownin: that second photo showing failing to bring the cpus online is really something else.. | 18:29 |
lownin | sarnold: thanks, I'll repost in #ubuntu-kernel | 18:29 |
lownin | sarnold: I agree. | 18:29 |
sarnold | jonah_: iirc you're only allowed four primary partitions with old-style formatting, not sure about the new GPT format.. | 18:29 |
jonah_ | sarnold: i only have four drives, so i'd just made 4 swaps partitions (1 on each drive) and 4 root partitions. then just installed at that but it didn't like it! | 18:32 |
patdk-wk | the question is, how should you use those 4 :) | 18:35 |
patdk-wk | raid0? raid1? | 18:35 |
patdk-wk | jonah_, did you use mbr or gpt? | 18:36 |
patdk-wk | gpt requires you make additional boot areas for grub | 18:37 |
lownin | sarnold: #ubuntu-kernel isn't very active, is it? | 18:39 |
sarnold | lownin: it may not be, I have to admit I've never used it.. but the topic looks kept up to date... | 18:40 |
lownin | sarnold: I was reading through their channel logs, and there are entire days where no one says anything. | 18:41 |
sarnold | must be nice :) haha | 18:42 |
lownin | =p | 18:42 |
jonah_ | patdk-wk: sorry trying to do raid10 | 18:55 |
jonah_ | just trying now with a 3rd raid volume which I've got a efi boot area set for each sda3 sdb3 sdc3 sdd3 etc... | 19:01 |
jonah_ | no idea if that will work! | 19:01 |
jonah_ | but at least it gives that a B for bootable label... | 19:01 |

bernierunns | What can I do about missing partition tables? I get an error when I boot the server that I have missing partition tables and it then asks to skip the mount or fix manually. | 21:20 |
bernierunns | I just skip it because i have no idea how to fix this issue. | 21:20 |

rattking | if the partition table is suppose to be missing then you should remove that entry from /etc/fstab.. this will remove that prompt | 21:21 |
bernierunns | OK, how do i display drive info so I can see whats going on with my drives? I'm fairly new to command line stuff. | 21:24 |
rattking | 'blkid' 'cat /proc/partitions' and 'df' will give some ideas | 21:25 |
bernierunns | ok, I'm checking that out now | 21:25 |
rattking | but it should have complained about the missing device at boot | 21:27 |
bernierunns | Could it be that I don't have an external drive configured to mount at boot? | 21:27 |
thresh | huh, https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1505839 | 21:28 |
ubottu | Launchpad bug 1505839 in debian-installer (Ubuntu) "Unable to install from text mode interface" [Undecided,Confirmed] | 21:28 |
rattking | its more likely there is a external drive configured to mount at boot that is either not attached or has been formatted so the UUID doesnt match whats in /etc/fstab | 21:29 |
bernierunns | OK, that makes sense, I can edit that info in vi right? | 21:31 |
rattking | yes, with sudo or as root | 21:31 |
