| 08:11 rcy | I want to use FAI to do ubuntu installations. Should I run the server from a debian machine, or ubuntu, or does it matter? The demohost installation has some issue with grub not being available when working from a feisty server |
| 08:12 glance | rcy: in the end it doesnt matter, its just up to you. |
| 08:13 rcy | ok... that's sorta what I suspected, I just wanted to make sure making the wrong choice wasnt going to cause me endless problems |
| 08:13 rcy | its taking me a little while to get my head wrapped around how this all works |
| 08:14 glance | anyhow it whill end whith you needing to write/customize some scripts to get it all working as you want it to. |
| 08:16 rcy | oh definitly |
| 08:17 rcy | im looking to just have the demohost installed and booting as the first step |
| 08:25 Mrfai | siretart: did you already tested 3.2betaxx with ubuntu? I like to release FAI 3.2 next week. |
| 08:38 rcy | should /srv/fai/nfsroot/proc be an actual proc filesystem on my faiserver? |
| 08:38 rcy | make-fai-nfsroot is failing because it cant remove that directory |

| 09:17 Mrfai | type mount and you will see that there are remaining mounts. These are from a previous make-fai-nfsroot call, that you've interrupted or suspended |
| Mrfai_ (~lange@suenner.informatik.uni-koeln.de) joined #fai. |
| 09:18 rcy | yeah yer right... I cancelled one |
| 09:25 siretart | Mrfai: yes, I was able to install it, but I think I had not dma on while installing, so it tool really ages |
| 09:25 siretart | Mrfai: I didn't boot the system yet, but I'm confident |
| 09:26 siretart | Mrfai: did you include the workaround for update-initramfs pointing to /bin/true? |
| 09:34 Mrfai_ | yep |
| 09:35 Mrfai_ | no dma is mostly cased by a missing kernel module inside the initramfs. If the generic ide driver is loaded before the special driver the the chipset, you do not have dma. |
| 09:52 rcy | I'm not sure what script is running atm, but I see "Mounting /dev/hda8 to /tmp/target/usr" followed by a bunch of "[: 93: ==: unexpected operator" errors |
| 09:52 Mrfai_ | put the fai.log to pste.debian.net. and also you disk_config file and format.log |
| 09:53 rcy | ok, ill wait till the install finishes |
| 10:06 rcy | well, after all that, it did work this time... i booted into the system! |
| 10:08 rcy | it immediatly rebooted though... is the fai.log available somewhere? |
| 10:11 Mrfai_ | on the install client in /var/log/fai, on the install server in homedir of $LOGUSER if you configured it to do so. Mmm, this maybe a FAQ for the wiki |
| 10:11 rcy | i did see stuff in the config files about it... but didnt bother touching it yet |
| 10:12 rcy | maybe it should write it to the target hd somewhere as well |
| 10:13 rcy | weird that it just rebooted automatically though... had i not been around to pull the ethernet, it would have started the install again |
| 10:15 Mrfai_ | it does write it into the target |
| 10:15 rcy | oh... where? |
| 10:15 rcy | i see /var/log/bootstrap.log, but thats not it |
| 10:16 Mrfai_ | /tmp/tar/var/log/fai |
| 10:16 Mrfai_ | sorry |
| 10:16 Mrfai_ | /tmp/target/var/log/fai |
| 10:17 rcy | excellent |
| 10:23 rcy | fai.log: http://paste.debian.net/34670 |
| 10:24 rcy | format.log: http://paste.debian.net/34671 |
| 10:24 Mrfai_ | now it's a FAQ: http://faiwiki/index.php/User_FAQ#Where_do_I_find_the_log_files.3F |
| 10:26 rcy | disk_config: http://paste.debian.net/34672 |
| 10:28 rcy | where do i find the code that does this: "Calling task_mountdisks"? |
| 10:30 Mrfai_ | /srv/fai/nfsroot/usr/lib/fai/subroutines and ...usr/lib/fai/mount2dir |
| 10:34 rcy | it might be nice if the echo calls in the various scripts did a echo "$0: ...", so one could more easily track down where things are coming from |
| 10:41 rcy | mount2dir is the only script with == in it that i can see... but it looks fine |
| Nick change: \sh -> \sh_away |
| 10:46 Mrfai_ | add set -x to if, then you will get much debugging output |
| 10:48 rcy | to if? I don't exactly know what you mean |
| Nick change: \sh_away -> \sh |
| 11:01 siretart | Mrfai: do you happen to have a quick workaround for having dma in live-initramfs? |
| woffs (~woffs@osiris.taz.de) joined #fai. |
| 11:45 Mrfai_ | s/if/it/ |
| 11:46 Mrfai_ | siretart: which chipset? IDe or sata. Sata sould work IMO since it always enables dma. |
| Action: h01ger thinks sata might depend on the kernel version as some sata chipsets are not supported by 2.6.18 |
| 12:01 h01ger | lazyb0y, http://udrepper.livejournal.com/17577.html - a quote: "For sysadmin types this means: do what you have to do with Xen for now. But keep the investments small. For developers this means: don't let yourself be tied to a platform. Use an abstraction layer such as libvirt to bridge over the differences. For architects this means: don't looking to Xen for answers, base your new designs on KVM." |
| 12:01 h01ger | interesting read |
| 12:02 oz_ | Xen is to die? |
| 12:02 siretart | Mrfai_: should be piix, but using libata |
| 12:08 Mrfai_ | which kernel version? check if piix is included into the initramfs. |
| 12:23 Lin | morning all (morning in brazil) |
| 12:23 Lin | how can I define the computer hostname after a fai instalation |
| 12:24 Lin | I have added lines like this in dhcp.conf |
| 12:24 Lin | host cyber01.copacabana { hardware ethernet 00:19:d1:46:5e:7d; fixed-address cyber01.copacabana; } |
| 12:24 Lin | and like this in /etc/hosts: |
| 12:25 Lin | 192.168.1.101 cyber01.copacabana.ibeu.org.br cyber01.copacabana |
| 12:25 Lin | but the hostname is just cyber01 not cyber01.copacabana (as I wish) |
| 12:25 Lin | any tips? |
| 12:30 Lin | h01ger: sorry for lameness. But what is the KVM model? |
| 12:32 Lin | kernel based virtual machine (GIYF) |
| 12:32 Lin | ;-) |
| 12:34 h01ger | :) |
| 12:35 Lin | h01ger: I have some Hypervisors here.. |
| 12:40 Lin | h01ger: as I could notice there is a lib (libvirt) to compile your codes with that enable the code run "natively" over KVM, something "like" java. |
| 12:42 Lin | seems weird since it doesn't create a full environment for every application. |
| 12:47 Lin | OMG! There is a pletora of VMs |
| 12:48 \sh | Mrfai, do you know any good nfs stress test tools? |
| 12:52 Mrfai_ | no. |
| 12:53 \sh | bonnie++ running on an nfs share is breaking everything ,-) |
| 12:55 Lin | \sh: maybe nfs does't like stress tests.. |
| 12:56 Lin | nfs doesn't even like of file copies. ;-) |
| 12:56 \sh | Lin, it loves stress tests...because if not, netapp solutions wouldn't be there on the market ,-) |
| 12:56 Lin | netapp... |
| 12:57 Lin | IMHO nfs is good for nothing (except for remote rootfs) |
| 12:58 Lin | netapp is a storage? |
| 12:58 Lin | based only on NFS? |
| 12:59 \sh | netapp is a san solution...i think low- to midrange (not so expensive and big as symetrix/emc) |
| 12:59 Lin | and the storage is shared using nfs? |
| 13:00 Lin | if so Im REALLY amazed. |
| 13:33 \sh | Lin, there are several methods..but nfs is one of the prefered ones... |
| 13:35 Lin | \sh: there are crazier people than I. |
| 13:39 \sh | Lin, why? it just works :) |
| 13:39 \sh | iozone is a good stress test tool for nfs , yeah |
| 13:39 Lin | \sh: nfs is unreliable. |
| 13:40 Lin | low security. |
| 13:41 \sh | Lin, this is not true :) |
| 13:42 \sh | well at least you shouldn't use nfs over internet...but inside a secure network it's quite good and a good solution for mass storage... |
| 13:42 Lin | we cannot create redundant shares with nfs |
| 13:43 Lin | nfs doesn't work in unreliable networs (TCP/IP) |
| 13:43 \sh | Lin, we can ;) |
| 13:43 Lin | how? |
| 13:43 Lin | you cannot just remount in another server or use a pool of servers |
| 13:43 \sh | Lin, just use heartbeat and use nfs3 over tcp |
| 13:44 \sh | you don't need...you just need several servers, run heartbeat on it, give him a single virtual ip and everything works |
| 13:44 Lin | nfs doesn't work *WELL* in unreliable networs (TCP/IP) |
| 13:44 Lin | \sh: have you tried this? |
| 13:44 Lin | \sh: doesn't show any freezes? |
| 13:45 Lin | \sh: I had bad times using NFS, mounts frozen, zombie processes, systems stoped. A complete chaos |
| 13:46 \sh | Lin, believe me it does...it does at lycos-europe, unity media (2nd biggest cable provider in germany) and it does at our company :) and I think in several more companies around the globe :) |
| 13:57 Lin | \sh: just a simple question. How do you synchronize the repository content? |
| 13:58 \sh | Lin, repository content? |
| 13:59 Lin | 2 nfs servers. |
| 13:59 Lin | a lot of files, someone request a file /data/firefox/firefox2.exe |
| 13:59 Lin | or someone write a new file on this repository. |
| 14:00 Lin | how do you keep both them synchronized? |
| 14:00 Lin | single rsync everyday? |
| 14:00 \sh | Lin, the sync is done via drbd |
| 14:00 \sh | Lin, it's something like raid1 over network |
| 14:00 Lin | i know drbd |
| 14:00 Lin | I use it here.. to syn my xen servers. |
| 14:01 Lin | drbd do not allow access to both devices at same time. just one. |
| 14:01 Lin | but Ok. I understood ;-) |
| 14:02 \sh | Lin, you just need one...push a MSA 1000 on your hp server and you are fine ;) |
| 14:03 \sh | or just (as we do) use 2 oem machines with 16x500GB sata hds in raid6 mode, which gives you around 7 TB storage... |
| 14:04 Lin | hp? we use dell ;-) there is some incopatibility? :-P |
