| inkata | Hi all, I'm learning uvtool + ubuntu cloud images for my KVM machine. When creating a new guest with uvt-kvm create it ends up running two disks. Why is that? | 00:06 |
| inkata | thanks | 00:06 |
| tsimonq2 | inkata: #ubuntu is probably the best place for this. I'd help you, but unfortunately, I'm on a machine with no VM capabilities at the moment, so I can't confirm or deny or test. | 00:07 |
| tsimonq2 | (and I don't know the tools well enough) | 00:07 |
| sarnold | tsimonq2: I think the docs send uvtool users to this channel :) | 00:07 |
| tsimonq2 | sarnold: oh? | 00:07 |
| sarnold | tsimonq2: yeah, see the bottom of https://help.ubuntu.com/lts/serverguide/cloud-images-and-uvtool.html | 00:07 |
| tsimonq2 | then nevermind, stay around and wait for someone to answer, sorry about that inkata :) | 00:08 |
| sarnold | inkata: a quick read through the source gives me the impression that it's probably creating a cloud-init datasource | 00:10 |
| sarnold | inkata: you can find more information on cloud-init here https://cloudinit.readthedocs.io/en/latest/ though I've found it severely underdocumented how you actually -use- cloud-init :/ | 00:10 |
| inkata | tsimonq2: thanks man, as sarnold mentions, the docs point here. | 00:10 |
| inkata | sarnold: roger | 00:11 |
| inkata | sarnold: can't make heads or tails of cloud-init :-/ | 00:21 |
| sarnold | inkata: you either? :( sigh. it looks so useful but I can't ever find anything that says "put this file <here> and run <command> there in order to use it with libvirt" or something similar... | 00:21 |
| inkata | sarnold: exactly lol | 00:22 |
| inkata | maybe it's a partition with a magic file on it or something | 00:23 |
| sarnold | inkata: is it still visible in the resulting VMs? that might explain an awful lot about how to use the thing :) | 00:23 |
| inkata | sarnold: it's a disk, it shows on dmesg but it's not mounted. let me reboot the guest to try and see what's in it and report back | 00:25 |
| rbasak | inkata: Ubuntu cloud images are undifferentiated. The second disk is a cloud-init datasource which differentiates it (eg. has your ssh public key on it). | 00:25 |
| rbasak | It tells your instance what to do when it boots, essentially. | 00:26 |
| rbasak | See http://cloudinit.readthedocs.io/en/latest/topics/examples.html for details of what it can do. With uvtool, you can pass this in using --user-data, to save having to mess with creating the datasource manually. | 00:28 |
| inkata | rbasak: do I pass a local file to uvtool? a plain file ? | 00:29 |
| rbasak | inkata: you pass anything cloud-init will accept as userdata. That can be a shell script with an appropriate shebang, I believe, but usually it's in cloud-init's cloud-config format, which is yaml and covers pretty much anything you might need in a declarative format. Documentation at http://cloudinit.readthedocs.io/en/latest/topics/format.html | 00:32 |
| rbasak | inkata: re-reading your question, yes - a file. | 00:32 |
| inkata | rbasak: /me gasps in awe that's quite useful.. let me try with a simple touch /tmp/newfile | 00:33 |
| rbasak | smoser: IMHO, http://cloudinit.readthedocs.io/en/latest/topics/examples.html should have every example start with #cloud-config. Otherwise people in a hurry will miss that, which I think will cause mostly silent failure, right? | 00:34 |
| sarnold | omg yes, if #cloud-config is required for some reason that absolutely should be in every single example :) | 00:35 |
| rbasak | inkata: note that if using uvtool, if you specify --user-data then uvtool can no longer inject your ssh public key, since it uses cloud-init userdata to do that and you're overriding it. | 00:35 |
| smoser | rbasak, definitely true. | 00:35 |
| rbasak | inkata: so in that case, you should write to ~ubuntu/.ssh/authorized_keys yourself, or make alternative arrangements. | 00:36 |
| rbasak | inkata: if you use cloud-config then it's easier since there's a yaml key you can use to provide your ssh public key. | 00:36 |
| inkata | rbasak: cloud-init is a regular package I should install in my KVm host or in my regular desktop? | 00:40 |
| inkata | cloud-config* sorry | 00:40 |
| rbasak | inkata: cloud-config is a format that is defined by cloud-init that it accepts - not a package. | 00:43 |
| rbasak | The format is a YAML schema, essentially. It is straightforward to write and modify by example. | 00:44 |
| inkata | rbasak: roger that | 00:44 |
| rbasak | inkata: look at http://cloudinit.readthedocs.io/en/latest/topics/examples.html, but stick "#cloud-config" at the top of any file you create so cloud-init knows it's getting cloud-config data. | 00:45 |

| inkata | rbasak: Re: #cloud-config file, how can I get the name of the new guest to be used in my file? it used to say the new_guest_name in the login screen, now it only says ubuntu | 01:51 |
| rbasak | inkata: set the hostname and set manage_etc_hosts to localhost. | 01:55 |
| inkata | rbasak: but how to set the hostname dynamically in the cloud file? I need to catch uvt-kvm create THISHOSTNAME | 01:57 |
| rbasak | inkata: you'll need to wrap uvt-kvm and create a temporary --user-data file. | 01:59 |
| rbasak | inkata: if you override with --user-data, uvt-kvm cannot then do it for you. | 01:59 |
| inkata | rbasak: got it. This is getting to be more cumbersome than getting a fat server ISO and installing it from scratch lol | 02:00 |
| rbasak | Really? :) | 02:01 |
| inkata | kinda yeah :-P | 02:02 |
| sarnold | man the only thing less documented than how to use cloud-init is how to use preseeding :) | 02:02 |
| inkata | rbasak: I'm setting the hostname to blahblah and it works!, but ssh keys are borked.. working on it.. | 02:04 |
| rbasak | Great! | 02:09 |

| inkata | rbasak: thanks man! | 02:11 |
| inkata | rbasak: sarnold it's aliiiiive!!! but needs mooar scripting than I anticipated or need right now. Thanks for your help guys, sleep tight! | 02:16 |

| wrksx | Wanted to upgrade from 14 LTS to 16 LTS, and got an issue with my /boot/grub/menu.slt | 09:12 |
| wrksx | it says the file changed, and the package maintainer's got a new version for this file. | 09:13 |
| wrksx | here is my old menu.lst http://paste.debian.net/hidden/b02dfb5f/ | 09:13 |
| wrksx | This is a server I'm only able to access through ssh so I'm not sure I'm goin to use that grub menu at all. | 09:14 |
| rbasak | wrksx: this could be bug 1485685 if you're using a cloud image? | 09:24 |
| ubottu | bug 1485685 in cloud-init (Ubuntu) "Users are prompted on upgrade of cloud images" [Medium,Triaged] https://launchpad.net/bugs/1485685 | 09:24 |
| wrksx | rbasak, ubottu, how can I confirm I'm using a cloud image? | 09:28 |
| rbasak | wrksx: how do you install the system? | 09:31 |
| wrksx | rbasak, it was installed by my hoster. I just ran an upgrade | 09:32 |
| wrksx | I suppose that mean it uses some kind of image anyway (since the hoster has to deploy a lot). But is that what you refer to as a cloud image I dunno | 09:33 |
| rbasak | If you have an /etc/cloud/build.info then your system is based on a cloud image | 09:33 |
| rbasak | If your hoster installed the system, perhaps they modified menu.lst. | 09:33 |
| wrksx | rbasak, I have no /etc/cloud | 09:34 |
| wrksx | rbasak, is that /boot/grub/menu.lst used to boot the server? | 09:35 |
| rbasak | Then it seems likely to me that your host modified menu.lst. | 09:35 |
| rbasak | Yes, depending on your host environment. | 09:35 |
| wrksx | rbasak, two major diff between the two files, the hoster's one is referencing /initrd.img and /vmlinuz symlinks, and the package maintainer version is directly referncing inside /boot. | 09:37 |
| wrksx | the other diff is that the hoster hass a biosdevname=0 on the kernel lines, which looks like important even if I don't know the purpose of it | 09:38 |
| Andrew__ | Looking to chat to someone about conjure-up and if it supports spaces defined in MAAS? | 09:44 |
| rbasak | stokachu: ^ | 09:49 |
| wrksx | https://wiki.ubuntu.com/Booting says that "Grub will find the /boot/grub/menu.lst which configures its interactive menu". I don't understand why this should be used to boot a server since no one is there to see the menu at reboot time | 09:50 |
| rbasak | We don't use that any more I don't think. | 09:52 |
| rbasak | It's still commonly used though when a host wants to boot a kernel directly rather than by emulating a regular system boot. | 09:53 |
| wrksx | rbasak, do you know a way to check what is used at boot time? | 09:53 |
| rbasak | No, the guest can be fooled. Ask your host. | 09:54 |
| wrksx | rbasak, oh damn. I was afraid of hearing that | 09:54 |
| rbasak | You could eliminate some methods by confirming they're not configured on the guest I suppose. But I don't really have the time to go through that, sorry. | 09:54 |
| rbasak | It's not clear to me if your menu.lst modifications were made by an Ubuntu installer, by an Ubuntu bug or by your host. | 09:55 |
| wrksx | rbasak, that's alright thanks for the help, always appraciate it | 09:55 |
| rbasak | Look into net.ifnames=0 - you might need this after upgrade to stop your NIC names changing. | 09:55 |
| rbasak | Also the grub-legacy-ec2 package, which your host may (or may not) use to boot your kernel directly. | 09:56 |
| stokachu | Andrew__: it uses juju underneath but there is no way to tell conjure-up to use a certain space | 10:21 |
| Andrew__ | Ok thanks - was trying to see if I could do all the network definitions in MAAS instead of doing in advanced configuration | 10:24 |
| Andrew__ | I have raised a issue around not being able to get into advanced configuration for cinder | 10:25 |
| Andrew__ | Is there a way to target nodes in MAAS from conjure up? | 10:25 |
| stokachu | Andrew__: re: cinder that should be fixed if you want to test ppa:conjure-up/daily-git | 10:26 |
| stokachu | Andrew__: there isn't a way to target specific maas nodes via conjure-up unfortunately | 10:26 |
| stokachu | Andrew__: the best you can do is set which node to bootstrap with using --bootstrap-to | 10:27 |
| === dosaboy_ is now known as dosaboy | ||
| Andrew__ | ok | 10:28 |
| wrksx | Okay so I fucked up my system trying to go from LTS 14 to 16 | 10:39 |
| wrksx | I was a bit careless because I thought there was no really important stuff on that box. | 10:40 |
| wrksx | Now it's gone I feel I underestimated the cost of that loss. | 10:40 |
| wrksx | System seemed not to boot | 10:41 |
| wrksx | Using an option from the hoster I've been able to restart in 'rescue' mode | 10:41 |
| Andrew__ | stokachu - all working in daily - thanks | 10:44 |
| Andrew__ | stokachu - I am going through and setting all the networks in conjure-up advanced configuration is there any way to share common network configurations? | 10:46 |

| robert17 | Hi. I'm trying to setup an existing Ubuntu-Server 14.04.5 LTS instance with an attached RAID-1 array. I do this all the time on all sorts of other boxes with no issue. Here, though, try as I might, I can create the array, manually assemble is from shell -- all looks good -- | 14:07 |
| robert17 | BUT, I can't manage to get it to assemble/start on boot. | 14:07 |
| robert17 | AFTER boot, I can simply 'mdadm --assemble --scan', and all's good. But auto-assemble? | 14:07 |
| robert17 | No dice .... Is there something unique, or not quite ready, in Trusty? | 14:08 |
| RoyK | robert17: did you mdadm --detail --scan >> /etc/mdadm/mdadm.conf && update-initramfs -u # ? | 14:22 |
| robert17 | RoyK: Yep. As always .... | 14:22 |
| robert17 | "Quadruple-checked" superblocks, etc etc | 14:23 |
| RoyK | check mdadm.conf if it has some ghosts | 14:23 |
| robert17 | 'ghosts'? | 14:23 |
| RoyK | old references to former arrays of the same name | 14:23 |
| robert17 | Ah. It does not | 14:23 |
| robert17 | No errors in boot log afaict. Just no startup. Kernel mod's loaded. Like I said, after startup, reassemble works perfectly. | 14:24 |
| robert17 | Just a quiet, no-start on boot. | 14:25 |
| RoyK | is the raid in any lvm config or in fstab? | 14:29 |
| robert17 | Nope, not yet. | 14:32 |
| robert17 | RoyK: appears to be unique to Trusty. Mine, anyway. Ubu16 works just fine. | 15:03 |
| RoyK | robert17: I don't think the raid will be activated until it's actually used | 15:32 |
| robert17 | 'used' ? as in ... it has to be mounted? | 15:33 |
| robert17 | Works fine "everywhere else" ... | 15:33 |
| RoyK | as in accessed | 15:38 |
| robert17 | hm. Worth a try ... doing so now. | 15:39 |
| robert17 | RoyK: Completely unneeded on Ubu 16 -- autoassembly on boot works with no access/mount, just mdadm.conf config. OTOH, on Ubu 14, no autoassembly on boot, UNTIL ... create an /etc/fstab mount for the array. Works now. | 15:48 |
| robert17 | IIUC, that's going to be a problem if I want to boot from the array ... | 15:48 |
| robert17 | It's got to assemble in order to GET to the /etc/fstab ... unless there's sufficient info in the initramfs | 15:49 |
| RoyK | robert17: I've used raid1 for boot devices on most versions of debian/ubuntu, and never seen an issue with that | 15:53 |
| RoyK | robert17: As I said, it usually assembles correctly, but isn't activated unless it's being touched by lvm or a filesystem or similar | 16:08 |
| robert17 | RoyK: Do you by anychance need to use "dolvm" or "lvmwait=" in grub cmd line? | 16:10 |
| RoyK | robert17: IIRC I've used lvwait once, but I don't remember the occation | 16:16 |
| robert17 | RoyK: fwiw, setting "GRUB_CMDLINE_LINUX="dolvm lvmwait=/dev/mapper/VG_TEST-LV_TEST", where /dev/VG_TEST/LV_TEST is a VG+LV on PV=/dev/md1 seems to do the trick. No /etc/fstab mount or /etc/rc.local needed. Of course, that still requires that there's a mountable FS somewhere on the array ... | 16:35 |
| Braven | hello | 17:17 |
| Braven | does anyone know how to prevent a IF that is configured for DHCP from registering in DNS | 17:18 |
| Freze | thanks Royk | 17:19 |

| madprops | the version in the repo has a bug | 18:24 |

| sarnold | madprops: you could download the patch from the github issue; apt-get source the mod_wsgi package, apt-get build-depends for the mod_wsgi package, and try applying the patch | 18:45 |
| sarnold | looks like our packages are quite a bit older than the patch on github, it might take some massaging, but it's worth a try | 18:45 |
