| Bray90820_ | How would I initialize an already created LVM snapshot | 01:04 |
| ChibaPet | Bray90820_: What do you mean by initialize? | 01:23 |
| Bray90820_ | There is what I believe is one that is already created but it's not in the logical volume manager | 01:25 |
| Bray90820_ | ChibaPet: | 01:25 |
| ChibaPet | If lvdisplay doesn't show it, it's probably not there. | 01:26 |
| ChibaPet | Note that (at least as far as I can remember) if you overfill an LVM snapshot, it goes away spontaneously. | 01:27 |
| Bray90820_ | ChibaPet: I think I figured out my issue with your help Thanks | 01:30 |
| Bray90820_ | It wasn't there so I am gonna retreat it f I can ever figure out what size it actually was | 01:30 |
| ChibaPet | Remember that if you create a snapshot, it will be capped by free extents in the volume group, and it will go away once it overfills. LVM snapshots aren't like ZFS snapshots. Not CoW. | 01:31 |
| ChibaPet | ...unless something has seriously changed recently. | 01:31 |
| Bray90820_ | ChibaPet: So does that mean to be able to use and or copy files to it while it's backing up would i need to create a logical volume snapshot | 02:06 |
| ChibaPet | Bray90820_: I'm not clear on how you'd want to usefully use the snapshot. I've only ever used LVM snapshots as backup sources. | 02:07 |
| ChibaPet | That said... | 02:07 |
| ChibaPet | You want to allocate sufficient extents to carry as much data as you expect to receive during the lifetime of the snapshot. | 02:08 |
| Bray90820_ | Like if i were to copy a 1GB video file to it while it was facing up I would need to have 1gb of extents | 02:09 |
| ChibaPet | I learned about their disappearing when I had something rsyncing the the device I'd snapshotted during a back-up. I'd overfill the snapshot space and the device I was backup up would show an uncorrectable read error. | 02:09 |
| ChibaPet | Basically, yeah. | 02:09 |
| ChibaPet | It's always possible I'm missing some detail of how you can use LVM snapshots. | 02:09 |
| Bray90820_ | Ok that's clear but... | 02:09 |
| ChibaPet | I'm a big fan of ZFS lately just because of the pain it avoids. | 02:09 |
| Bray90820_ | Right now unless I am already connected to my server it is unavailable while I am backing it up | 02:10 |
| ChibaPet | Seems safe then. | 02:10 |
| ChibaPet | Usually when I'm allocating pools I explicitly leave space for snapshots. | 02:10 |
| Bray90820_ | ChibaPet: do you have some time to help me create a backup script because I am kinda a noob when it comes to this stuff someone else created one for me back in early December but I don't seem to have a text version of it to change things | 02:12 |
| Bray90820_ | He compiled it in some weird way and I think it's easier to just create a new script | 02:12 |
| ChibaPet | Bray90820_: Um. Half a sec. | 02:13 |
| Bray90820_ | ChibaPet: Just tell me when your back | 02:16 |
| ChibaPet | Bray90820_: Sorry, been here, but a co-worked walked up and distracted me. | 02:18 |
| ChibaPet | Let me grab something. | 02:18 |
| Bray90820_ | Ok | 02:18 |
| Bray90820_ | Just tell me when your back and ready to talk :P | 02:18 |
| ChibaPet | Just finding the right version. | 02:19 |
| ChibaPet | The thing I just found is for tape drives, but I have something that does LVM. | 02:19 |
| Bray90820_ | What did you find | 02:21 |
| ChibaPet | This script assumes you want to dump stuff over ssh, but that's not an awful assumption nowadays. | 02:22 |
| ChibaPet | Here's an example config: https://bpaste.net/show/dc3e07859822 | 02:22 |
| ChibaPet | that would want to live as /etc/ndump.conf | 02:22 |
| ChibaPet | Here's a script which uses that config: https://bpaste.net/show/7eca9e0e4e83 | 02:23 |
| Bray90820_ | Did you find a copy of the script I have on my computer? | 02:23 |
| ChibaPet | What? | 02:23 |
| ChibaPet | No. | 02:23 |
| ChibaPet | I wrote that. | 02:23 |
| Bray90820_ | Aaahhh alright | 02:24 |
| Bray90820_ | Like I said I am a noob so I am not sure what any of that really means | 02:24 |
| ChibaPet | So, in the config, set up an ssh private key somewhere, and point to it with a key directive. Set up the account with the public half somewhere. Test the ssh connection. | 02:24 |
| ChibaPet | Um. | 02:24 |
| Bray90820_ | Sorry | 02:25 |
| ChibaPet | I don't know. There's a tool that'll do LVM-aware back-ups for you, but you have to put in the time to read what it does and either use it or set up something similar. | 02:25 |
| Bray90820_ | It's ok if you don't want to but would you mind creating a script for me :P | 02:25 |
| ChibaPet | so, for the lvm entries, vgdisplay will show you free extents in your volume group | 02:25 |
| ChibaPet | Bray90820_: Use... that script... that I just gave you. | 02:26 |
| ChibaPet | That's why I gave it to you, so you could use it. Set up a config file, and away you go into happy back-up land. :) | 02:26 |
| Bray90820_ | ChibaPet: I meant one specific to my system | 02:26 |
| ChibaPet | I'm going to go home now, as it's been a long day, but the very simple config makes it utterly tuned and tailored for your very specific computer. | 02:27 |
| Bray90820_ | chi | 02:27 |
| Bray90820_ | ChibaPet: I will have a look | 02:27 |
| ChibaPet | Alternately, you can look at things like CrashPlan if you want to set something up without effort. | 02:27 |
| Bray90820_ | I do not wanna do online bqackup | 02:27 |
| ChibaPet | For my ndump tool, you need Perl (which you should already have) and the dump/restore commands, which are easily installed. | 02:28 |
| Bray90820_ | I'll have a look and if I have any questions can I contact you later? | 02:28 |
| ChibaPet | If you don't want to use ssh, chop out the line with /usr/bin/ssh -i in it and change the "logname" lines. | 02:29 |
| Bray90820_ | I do wanna use SSH | 02:29 |
| ChibaPet | kk | 02:30 |
| ChibaPet | Yeah, I'll be back online in a couple hours, and I'll read scrollback. | 02:30 |
| Bray90820_ | Ok | 02:30 |
| Bray90820_ | Thanks | 02:30 |
| Bray90820_ | I am kinda lost already with the first line | 02:30 |
| Bray90820_ | I totally don't understand any of this | 02:30 |
| ChibaPet | Bray90820_: Well. You have two options. | 02:30 |
| ChibaPet | If you're interested in learning stuff, something like what I pasted in is a good start. If you just want stuff backed up, I'd look at http://www.tarsnap.com/ or http://www.code42.com/crashplan/ | 02:31 |
| ChibaPet | CrashPlan lets you host your back-ups on a local system if you don't want to go offsite. | 02:31 |
| ChibaPet | There are likely other tools that'd work too. Amanda used to be nice. | 02:32 |
| Bray90820_ | ChibaPet: I would prefer to learn stuff | 02:32 |
| Bray90820_ | I just don't really know where to state | 02:32 |
| ChibaPet | http://www.amanda.org/ | 02:32 |
| ChibaPet | Well. Note that if you set up any of these tools (Amanda is free) you'll learn stuff in the process. | 02:32 |
| ChibaPet | It's entirely up to you which level of effort you want to target. :) | 02:33 |
| Bray90820_ | Like i said I'm happy with use your script but i don't know where to state with it | 02:33 |
| ChibaPet | Um, to boil it down, my script scaffolding just wraps the process of making an LVM snapshot, using it as a target for the age-old, still-perfect dump tool, and then cleaning it up. | 02:33 |
| ChibaPet | Here, start with this: install dump and restore, and read the man pages. That's the critical bit. | 02:34 |
| Bray90820_ | I don't even know how to edit it for my own use | 02:34 |
| Bray90820_ | I don't know perl | 02:34 |
| ChibaPet | Hrm. So, the only thing you'd need to edit is /etc/ndump.conf, and there are editor tutorials out there. | 02:34 |
| ChibaPet | You don't need to edit the Perl to use it, you'd edit the config. There's nothing system-specific in the code itself. | 02:35 |
| ChibaPet | The config isn't Perl, it's just a text file with key/value pairs. | 02:35 |
| Bray90820_ | Should I edit it on the computer I want to backup or the computer I am backing up to? | 02:35 |
| ChibaPet | For this, the config needs to be /etc/ndump.conf on the computer that you'll back up. | 02:36 |
| Bray90820_ | Alright | 02:37 |
| Bray90820_ | Thanks | 02:37 |
| ChibaPet | The script will be on that computer too. Run it as root. The only thing that needs to be on the target (backup-holding) computer is an account to connect to and sufficient space to store the dumps. | 02:37 |
| ChibaPet | If you save the script as "ndump" somewhere in your path, you'd run it by saying "ndump 0" to get a level 0 dump, "ndump 1" to get a level 1 dump, and so forth. | 02:37 |
| Bray90820_ | And the dumps are? | 02:38 |
| ChibaPet | man dump | 02:38 |
| Bray90820_ | Are the sums the data that is being backed up? | 02:38 |
| ChibaPet | sudo apt-get installd ump | 02:38 |
| ChibaPet | sorry, sudo apt-get install dump | 02:38 |
| ChibaPet | sums? | 02:38 |
| Bray90820_ | I meant dumps | 02:38 |
| ChibaPet | The dumps are the data you're backing up. A level 0 dump is everything. A level 1 dump is incremental and has everything since the last level 0 dump. Level 2 has everything since the last level 1 dump. Etc. | 02:39 |
| ChibaPet | This book used to and might still have good documentation of how to plan dump rotations, etc: http://admin.com/ | 02:40 |
| Bray90820_ | Thanks | 02:41 |
| Bray90820_ | You should go home | 02:41 |
| ChibaPet | Hi, sorry, yeah, work stuff popped up again. | 02:43 |
| Bray90820_ | Alright | 02:44 |
| ChibaPet | Um. So, read the dump man page, and ... I'm not finding good docs for dump rotations right now, but I can look later. | 02:45 |
| ChibaPet | You could achieve the same thing I'm doing in that Perl script with shell script, FWIW. | 02:45 |
| ChibaPet | Anyway, I'll be back and I'll answer any questions you leave in the interim. | 02:45 |
| Bray90820_ | Yea | 02:48 |
| Bray90820_ | I need lots and lots and lots of help | 02:48 |
| Bray90820_ | Like I said I don't even know where to begin | 02:49 |
| Bray90820_ | Think of me as a grandmother who doesn't speak computer at all | 02:52 |
| Bray90820_ | Events That is not me | 02:52 |
| Bray90820_ | *Eventho | 02:52 |
| ChibaPet | Bray90820_: I'll be a bit distracted: https://www.youtube.com/watch?v=qUAmTYHEyM8 | 04:22 |
| ChibaPet | That's happening right now. Live stream. | 04:22 |
| Bray90820_ | ChibaPet: I am actually working on my own script at the moment that doesn't have much to do with your script | 04:22 |
| ChibaPet | Good. Best way to learn. :) | 04:22 |
| ChibaPet | Anyway, I'll check in occasionally. | 04:23 |

| Guest84880 | i am banned from ubuntu channel how can i get back | 12:41 |
| Guest84880 | i am sorry about what i did | 12:41 |
| Guest84880 | i didnt understand what one guy said clearly | 12:42 |
| Guest84880 | hello? | 12:43 |
| Guest84880 | can someone say my oplogize to that guy please? | 12:43 |
| Guest84880 | hello? | 12:44 |
| lordievader | Wasn't there some channel in the message when you were banned? | 12:45 |
| Guest84880 | no | 12:46 |
| Guest84880 | i didnt see | 12:46 |
| Guest84880 | i think that guy that banned me was so angry | 12:46 |
| Guest84880 | he didnt offer any channel for apologize | 12:46 |
| Guest84880 | his name starts with k1 i think | 12:47 |

| KinoAA | Hello, do you know a good tool to monitor log and server access ? | 13:30 |
| tocotron | this is better | 13:32 |
| tocotron | hello | 13:33 |
| lordievader | KinoAA: Read the auth log? | 13:33 |
| KinoAA | Yeah, auth (ssh), page access, jekyll page access, all my log in a same place. | 13:35 |
| KinoAA | (I'm looking at nagios for now) | 13:35 |
| lordievader | KinoAA: Setup your logging system to output it to the same file? | 13:35 |
| tocotron | my question is this: How do dhcp-server and bind9 work together? after dhcp acked an IP, can bind9 be informed about the IP, so that the hostname resolves automatically? | 13:35 |
| KinoAA | lordievader: lol, it is going to be a mess ;) | 13:36 |
| lordievader | KinoAA: I'm not really sure what you are after ;) | 13:36 |
| tocotron | The thing is llike that: isc-dhcp always assigns the same IP to the same devices without me having this configured in dhcpd.conf. So, first, I'd like to know where the MACs are cached. After that I want to make bind9 aware of these assignments | 13:42 |

| Roge152 | Hi, I want to suspend an install of ubuntu server 14.01 over ssh. the command pm-suspend or its cousins pm-hibernate execute but have no effect at all. Does anyone have any ideas what could be wrong ? | 18:27 |
| Roge152 | 14.04* | 18:28 |
| ChibaPet | Roge152: Are you running them as root, and they're definitely installed? (pm-utils) | 18:29 |
| ChibaPet | And I'm assuming you have a way to wake it up later...? | 18:29 |
| nacc | Roge152: https://help.ubuntu.com/community/PowerManagement/Hibernate ? | 18:29 |
| Roge152 | running with sudo yes, they are installed (pm-utils) and I do have WOL working yes. | 18:29 |
| ChibaPet | hrm | 18:30 |
| nacc | Roge152: it mentions that pm-utils uses uswsup by default, so i'd test with that directly | 18:30 |
| Roge152 | ok I'll have a read | 18:30 |
| nacc | iirc, there's also a debug mode for swsup, but i can't remember how to invoke it | 18:30 |
| nacc | where it essentially does a dry run of suspend and resume | 18:30 |
| ChibaPet | Roge152: If you could do us the favour of noting what it once when you've solved it, I'd love to know. That's not something I'd tend to expect to see fail. | 18:31 |
| nacc | might be one of the values you can put in /sys/power/state | 18:31 |
| ChibaPet | s/once/was/ | 18:31 |
| Roge152 | Sure, if I figure out why I'll pass it along. | 18:31 |
| Roge152 | hmm. well, its clear why s2disk won't work. I have no swap setup atm. s2ram also doesn't work it says that "/sys/power/state does not exist; what kind of ninja mutant machine is this ? heh | 18:43 |
| nacc | heh | 18:44 |
| nacc | Roge152: i was wondering if the server kernel doesn't have suspend enabled? | 18:44 |
| ChibaPet | That'd inhibit hibernation, but I can't see why it'd affect suspending. | 18:44 |
| ChibaPet | nacc: I don't believe there's a distinct server kernel. I start my installs from the server ISO and suspend works here. | 18:45 |
| nacc | ChibaPet: ah you're right | 18:45 |
| nacc | Roge152: this might help with debugging: https://wiki.debian.org/Suspend | 18:45 |
| nacc | /var/log/pm-suspend.log ? | 18:45 |
| Roge152 | ok pm-hibernate works now after adding swap | 18:53 |
| ChibaPet | But, suspend? | 18:54 |
| Roge152 | still no suspend | 18:54 |
| Roge152 | lol and while the machine woke back up, its unreachable after hibernate. *facepalm* | 18:58 |
