| === io is now known as IdleOne | ||
| jrwren | i've been doing this too long to have never done that. where can I send the thanks hitsujiTMO ? :) | 01:17 |
| hitsujiTMO | you can fsck a unmount or readonly filesystem. so remounting ro should be safe | 01:17 |
| Bitwise | It seems reinstalling courier doesn't replace /etc/courier with fresh files. Am I missing something here? | 01:19 |
| sarnold | Bitwise: if you apt-get purge courier it'll clear all the configs, then a fresh apt-get install should put them back | 01:23 |
| Bitwise | Saved the day again! | 01:25 |
| jrwren | hitsujiTMO: i was hoping I could force remount readonly like kernel does when there are disk errors. | 01:33 |
| jrwren | I get mount: /mnt is busy | 01:33 |

| jrwren | yup | 01:34 |
| jrwren | well, mount -o remount,ro /mnt | 01:34 |
| jrwren | I'd think -o before device | 01:35 |
| hitsujiTMO | jrwren: try adding the n flag | 01:37 |
| jrwren | its not my root fs, shouldn't need it, but I'll try | 01:39 |
| hitsujiTMO | jrwren: you may have to kill anything that has a file open with fuser | 01:39 |
| jrwren | same thing. | 01:39 |
| jrwren | yeah, the fuser/lsof thing is the same as unmounting. | 01:40 |
| hitsujiTMO | altho i'm sure i've done this with / but on debian tho | 01:40 |
| jrwren | i'm in ssh, but any way I can remote an alt+sysreq+U ? | 01:40 |
| jrwren | or make that syscall or something? | 01:40 |

| jrwren | but I want to. | 01:41 |
| sarnold | jrwren: hehe, I meant it as a question to hitsujiTMO -- I'm a bit happy you thought of the same thing | 01:41 |
| hitsujiTMO | jrwren: echo "command key" > /proc/sysrq-trigger | 01:41 |
| sarnold | jrwren: that'd be echo u > /proc/sysrq-trigger | 01:41 |
| sarnold | 's' first if you want to sync | 01:42 |
| hitsujiTMO | sarnold: hmm, not sure was a few years back | 01:42 |
| jrwren | this is getting into crazy territory. I think I'll wait until I'm done reading from that FS. | 01:42 |

| hitsujiTMO | resizing an ext partition "should" be trivial enough to be able to do it even when its dirty. | 01:45 |

| RoyK | raid1ubuntu: sw raid? | 13:55 |
| RoyK | raid1ubuntu: anyway - it should work well | 13:55 |
| RoyK | just install grub on both disks (if it's sw raid) | 13:55 |
| raid1ubuntu | RoyK: host based (intel embedded raid server technology ii) | 13:55 |
| RoyK | raid1ubuntu: using that setup myself | 13:55 |
| RoyK | raid1ubuntu: then it's probably fakeraid. better not use it | 13:55 |
| RoyK | better use md raid | 13:55 |
| raid1ubuntu | its md raid | 13:56 |
| xnox | RoyK: intel matrix raid, managed by mdadm is actually ok. | 13:56 |
| RoyK | oh - didn't know that | 13:56 |
| xnox | RoyK: ditto ddf. all others are crap and thus only supported by dmraid =) | 13:56 |
| RoyK | raid1ubuntu: I'm using mdraid mirrors for boot on serveral servers - works like a charm | 13:56 |
| raid1ubuntu | RoyK: ubuntu setup automaticall detected it. and now wants to install grub on /dev/md126 | 13:56 |
| xnox | raid1ubuntu: installing grub onto /dev/md126 is correct. | 13:57 |
| RoyK | that's wierd. I thought grub should go to the host drives | 13:57 |
| xnox | raid1ubuntu: i had success with UEFI booting off intel matrix raid with mdadm, but not with BIOS/mbr. | 13:57 |
| raid1ubuntu | xnox: install on MBR (yes/no) in setup, i select yes | 13:57 |
| xnox | RoyK: no, the motherboard knows about the fakeraid array and thus has options to boot of the raid. | 13:58 |
| RoyK | xnox: ok - never used fakeraid | 13:58 |
| xnox | raid1ubuntu: yeah, that's correct -> but my motherboard didn't like it and failed to boot =( | 13:58 |
| raid1ubuntu | if i select NO it asks me for a device | 13:58 |
| xnox | raid1ubuntu: you should install into MBR. | 13:58 |
| xnox | raid1ubuntu: of /dev/md126 device. | 13:58 |
| raid1ubuntu | xnox: ok, but that fails | 13:59 |
| xnox | raid1ubuntu: and in firmware configuration (ctrl+I on boot) make sure it's marked as bootable. | 13:59 |
| xnox | raid1ubuntu: yeah =/ works with UEFI just fine though.... | 13:59 |
| RoyK | xnox: what would be the difference between using fakeraid and ditching that altogether for plain mdraid? | 13:59 |
| xnox | raid1ubuntu: in that case try installing onto a partition, instead of mbr e.g. /dev/md126p1 | 13:59 |
| RoyK | xnox: why not the host drives? | 14:00 |
| raid1ubuntu | ok i will try it | 14:00 |
| raid1ubuntu | i have installed the whole OS on the raid1 array | 14:00 |
| xnox | RoyK: different ondisk format and different sets of events / controllers. | 14:00 |
| xnox | RoyK: if you install to the host drives, you can hose the intel-matrix-raid on disk format. | 14:01 |
| xnox | (cause our grub is big and uses extended area i believe) | 14:01 |
| xnox | RoyK: then again if all fails, one can try that.... | 14:01 |
| RoyK | xnox: but what are the advantages of using fakeraid instead of just mdraid? | 14:02 |
| xnox | RoyK: plus motherboard bios/firmware sees and checks assembled array and tries to boot that.... not the underlying disks. | 14:02 |
| xnox | RoyK: in my experience fakeraid resysncs faster, and you can migrate it offline using firmware tools only - preboot. | 14:03 |
| xnox | (e.g. replace and rebuild a spare or failed drive) | 14:03 |
| xnox | RoyK: plus it works for dual boot installations as one can have windows on the same array with linux. | 14:04 |
| RoyK | that's inded a plus | 14:04 |
| xnox | RoyK: whereas with mdadm one can't install windows on top of it. | 14:04 |
| xnox | RoyK: people say that "intel firmware sends better/faster notifications about failed drives" but i'm skeptical about that =) | 14:05 |
| RoyK | guess I'll stick to old md for the moment | 14:05 |
| RoyK | that or zfs | 14:05 |

| raid1ubuntu | xnox: i tried /dev/md125 ..126 and md127 for grub but it always failed. i tried also /dev/sda | 14:09 |
| raid1ubuntu | xnox: it says something about "... disk not found" in dmesg (see picture) | 14:10 |
| xnox | raid1ubuntu: have a non-raided bootloader elsewhere. | 14:10 |
| xnox | raid1ubuntu: or just use stock mdadm instead of intel-raid. | 14:10 |
| xnox | raid1ubuntu: do you need/must use intel-raid, or can you use any raid? | 14:10 |
| xnox | raid1ubuntu: https://help.ubuntu.com/12.04/serverguide/advanced-installation.html | 14:11 |
| raid1ubuntu | i could use software-raid but i guess its slower than the intel one, right? | 14:11 |
| xnox | raid1ubuntu: no depends yes | 14:11 |
| xnox | raid1ubuntu: using raid, you are taking a penalty hit anyway. With raid1, your write is always the slowest of the two drives and reads are upto 2x faster. | 14:12 |
| xnox | raid1ubuntu: given processing / physical limitations it's a bit longer that slowest drive to write, and a bit less than 2x read gain. | 14:12 |
| xnox | raid1ubuntu: the difference between mdadm vs fakeraid is negligible. | 14:12 |
| raid1ubuntu | xnox: yeah i know, i just mean raid1 on software is slower than raid1 host based, thats what i guess, otherwise the raid controller would make no sense^^ | 14:13 |
| xnox | raid1ubuntu: ..... intel matrix raid controller is software based, it's just software compiled on the rom on your motherboard. It's not actually server-grade hardware raid controller. | 14:13 |
| raid1ubuntu | xnox: maybe i just only need to fix the "disk not found" problem | 14:14 |
| xnox | raid1ubuntu: you could use dmraid. | 14:14 |

| xnox | raid1ubuntu: typically, you'd boot into firmware and setup raid arrays as you wish. Have you done that? | 14:19 |
| raid1ubuntu | xnox: yes i have created one big array with two disks | 14:19 |
| xnox | raid1ubuntu: then during installation, you should _not_ setup any raid. | 14:19 |
| xnox | raid1ubuntu: if it asks you to activate things say yes. | 14:20 |
| raid1ubuntu | in the curses-based setup it tells me that it has detected sata-raid hardware, i select with yes and in manual partioning its there with the raid1 array | 14:20 |
| xnox | raid1ubuntu: during install select "use full disk, use lvm" (default option) and select only one drive -> that raid1 array. | 14:20 |
| xnox | raid1ubuntu: yeah so just install onto that. | 14:20 |
| raid1ubuntu | xnox: if i select this, its only showing up the usb-stick i am installign from | 14:21 |

| hallyn | tych0: when the lxc-create is hung,c an you confirm that locale-gen is running? | 14:29 |
| tych0 | hallyn: yes, although it'll take me a few minutes to get back there, but i can do that | 14:29 |
| hallyn | tych0: well, just setting yoru LANG to en_GB.UTF-8 in the script may fix it | 14:29 |
| tych0 | ok, will do | 14:30 |
| hallyn | there is some sort of hornet's nest lurking in the locale stuff, but I don't know what's going to come of it | 14:30 |

| raid1ubuntu | my server got 32gb ram how big should the SWAP partition be ? | 14:52 |
| xnox | raid1ubuntu: default - 32gb if you want suspend/hybernate to have a chance at working | 14:53 |
| xnox | raid1ubuntu: i use 32GB swap with 32GB of RAM on my desktop =) | 14:53 |
| * xnox ponders if can class myself as server.... | 14:53 | |
| raid1ubuntu | xnox: for a always-up server with no hibernate required ? | 14:55 |
| xnox | raid1ubuntu: you still want swap.... e.g. when i'm running big databases they use swap as disk-cache thus speeding up IO | 14:55 |
| raid1ubuntu | xnox: the machien is going to be hosted in a data-center of my university (yeah i really managed to get them host my server :D) | 14:55 |
| xnox | raid1ubuntu: things go blazingly fast if you can store 10GB of data in ram and move it about. | 14:56 |
| xnox | raid1ubuntu: i presume you have like terabyte drives that 32GB of swap is peanuts and a big performance gain. | 14:56 |
| raid1ubuntu | xnox: ok i will use 64gb | 14:59 |
| raid1ubuntu | xnox: the setup does not offer any raid-menus on partioning screen (i have disabled the controller and want to go for soft-raid now) any idea how to enable them? | 15:00 |
| raid1ubuntu | xnox: there is no fdisk in F2 console | 15:00 |
| xnox | raid1ubuntu: follow step-by-steps i've pasted to you earlier. | 15:02 |
| xnox | raid1ubuntu: go into something else / manual, enter configure raid, configure your raid1, back-out back to "Guided partitioning", select default install and then you'll be offered to install onto configured software raid device. | 15:03 |
| xnox | https://help.ubuntu.com/12.04/serverguide/advanced-installation.html | 15:03 |
| raid1ubuntu | xnox: thats what i am actually doing (thx for the link) but there was no free disk.. i managed to fix the problem by selecting the sdba, select delete, cancel (this would take hours) and go back to the setup main menu, and reenter partioning, no i am able to create free disk space .... and NOW there is a raid menu.. *phew* | 15:05 |

| raid1ubuntu | is there a way to skip swap space wiping at the end of the setup? | 15:38 |
| hallyn | utlemming: so hm. it looks like it is defaulting to compat=1.1 which i think should be ok... | 15:52 |
| hallyn | (meaning it's a bug) | 15:53 |
| hallyn | utlemming: presumably you can try compat=1.0... | 15:53 |
| hallyn | no that isn't valid | 15:53 |
| utlemming | hallyn: yeah, I tried compat=0.10 and it failed | 15:53 |
| utlemming | hallyn: per what I found, you need 0.10 for pre-1.1 versions | 15:54 |
| hallyn | d'oh. i missed htat you were on 12.04 for the mount | 15:54 |
| utlemming | hallyn: yeah, the problem is going form trusty to precise :/ | 15:54 |
| hallyn | utlemming: but 0.10 works everywhere? | 15:55 |
| utlemming | hallyn: it seems that it works except on precise | 15:55 |
| hallyn | I see - in your pastebin, that's the same file? | 15:56 |
| utlemming | hallyn: it is...test.img created on latest trusty build, and then copied to the latest precise build | 15:57 |
| hallyn | utlemming: please open a bug. i'll try to reproduce it with upstream qemu git, hand-built as 1.7 and 1.2 trees | 15:57 |
| hallyn | (so i can file against upstream) | 15:58 |
| utlemming | hallyn: sure, doing so now | 15:58 |
| hallyn | thx | 15:58 |
| hallyn | utlemming: fwiw there are some other qcow2 related bugs in trusty's git whic i need to nail down | 15:59 |
| utlemming | hallyn: ack, good to know | 15:59 |
| tych0 | hallyn: so locale-gen is not running when lxc-create is hung | 15:59 |
| tych0 | and setting LANGUAGE, LANG, and LC_ALL to en_US.UTF-8 didn't fix anything :-( | 16:00 |
| hallyn | tych0: please file a bug; i'll lose track otehrwise | 16:00 |
| tych0 | hallyn: ok, on ubuntu/lxc or just lxc? | 16:00 |
| hallyn | ubuntu/lxc | 16:00 |

| tych0 | hi hallyn, when i do an lxc-start, i'm getting: lxc-start: command get_state failed to receive response | 19:55 |
| tych0 | any ideas what's up? | 19:55 |
| hallyn | tych0: again - is this on trusty? lxc from ppa, or from trusty archive? | 19:56 |
| tych0 | trusty archive, sorry | 19:57 |
| hallyn | tych0: how exactly did you create the container? | 19:57 |
| hallyn | tych0: can you do 'lxc-start -n <container> -l trace -o outout' and then pastebinit outout? | 19:57 |
| tych0 | sudo lxc-create sudo lxc-create -n juju-bootstrap -t ubuntu-cloud -- -r precise | 19:58 |
| tych0 | although when i install cgroup-lite it seems to work | 19:58 |
| tych0 | hallyn: that's enough of a workaround for me; do you want me to trace it? | 19:58 |
| hallyn | srgraber: ^ | 19:59 |
| hallyn | tych0: lxc is supposed to require cgroup-lite | 19:59 |
| tych0 | ah | 19:59 |
| tych0 | :-) | 19:59 |
| hallyn | so until cgmanager is in main, yes you must have cgroup-lite installed | 19:59 |
| tych0 | ok, cool | 19:59 |
| tych0 | that answers my question, thanks! | 20:00 |

| === mwhudson is now known as zz_mwhudson | ||
| hallyn | tych0: ok back to your locale issue :) can you reproduce the issue by just putting the lxc-create command inside a 2-line #!/bin/sh script? | 20:21 |
| hallyn | tych0: and if so, can you do "env" right above the lxc-create, and pastebin the result? | 20:22 |
| tych0 | hallyn: no i did try that | 20:22 |
| tych0 | but i can do an env right before i run it in the script i'm doing now | 20:22 |
| hallyn | and it fails that way? | 20:22 |
| tych0 | hallyn: doesn't fail in a plain shell script | 20:29 |
| tych0 | just in our crazy cloud installer script | 20:29 |
| tych0 | so i'll have that run env and post that on the bug | 20:29 |
| hallyn | tych0: actually i think locale isn't to blame here. i can reproduce your warnings, without a hang | 20:31 |
| hallyn | i suspect actually that what you had | 20:31 |
| hallyn | was a debconf menu waiting for input | 20:31 |
| tych0 | yep | 20:31 |
| tych0 | that's what i was thinking too | 20:31 |
| tych0 | hung in timzeone | 20:31 |
| hallyn | but why... you don't get the debconf when you do it by hand | 20:32 |
| hallyn | stgraber: is there a way to tell apt-get that it should be non-interactive? | 20:32 |
| hallyn | (regarding bug 1282657) | 20:32 |
| uvirtbot | Launchpad bug 1282657 in lxc "lxc-create hangs in some cases on trusty" [Undecided,Incomplete] https://launchpad.net/bugs/1282657 | 20:32 |

| hallyn | time for some git bisect goodness | 22:42 |
| hallyn | i should come up with a cool script like arges does | 22:43 |
| hallyn | except every compile requires manual intervention, so it probably wouldn't work too well | 22:43 |
| hallyn | arges: actually... have you seen this bug? if you start kvm with a qcow backin store, it works fine on bare metal, but in nested grub fails to load the kernel | 22:44 |

| Bitwise | Hi, how should roundcube be configured in relation to postfixadmin and the maildb? I'm following this guide: http://flurdy.com/docs/postfix/ | 22:51 |
| Bitwise | I'd imagine one login should get into all of those services. | 22:51 |
| Patrickdk | first, what does any of what you said have to do at all with same random link you found in the internet? expecially that link | 22:56 |
| Patrickdk | as roundcube is an imap client, it should be configured for your imap server, and has nothing to do with postfixadmin | 22:56 |
| Bitwise | I'm asking about making one login for all of them. | 22:57 |
| Patrickdk | for all of what? | 22:58 |
| Patrickdk | so far I only see postfixadmin and maildb | 22:58 |
| Bitwise | postfix, postfixadmin, roundcube, courier | 23:00 |
| Patrickdk | in that case, you just have to make courier work | 23:00 |
| Patrickdk | and make it work the way postfixadmin expects | 23:00 |
| Patrickdk | though, I dunno why you want to make life so hard on yourself | 23:01 |
| Bitwise | Patrickdk, I think my courier configuration is correct. | 23:04 |
| Patrickdk | then there you go then | 23:06 |
| Patrickdk | everything uses the same password, time to move on | 23:06 |

| Patrickdk | why would that be valid? | 23:11 |

| Bitwise | In /etc/hosts I have 127.0.0.1localhost\n127.0.0.1mail.mydomain.tld | 23:49 |
| sarnold | use whois to find your authoritative resolvers; use dig or host on each of those authoritative servers in turn to query for your MX and then to query the address of the name returned for the MX | 23:49 |
| sarnold | you should probably delete that last line -- having 127.0.0.1 reverse-lookup to something other than localhost is probably going to break something. | 23:49 |
| sarnold | change it to 127.0.1.1 or 127.0.2.1 or something if you must keep it | 23:50 |
| sarnold | but having a fake entry in hosts is going to make troubleshooting your broken DNS so much arder | 23:50 |
| Bitwise | $ whois mydomain.tld -> NOT FOUND | 23:53 |
| sarnold | yikes, time to see how good your registrar's support group is :) | 23:53 |
