| 10:16 vineeth | hello guys.... |
| 10:17 vineeth | i'm testing fai on an ubuntu laptop with a client VM using VirtualBox.. |
| 10:17 vineeth | it's getting the ip address and pxe info from tftp in the server... |
| 10:18 vineeth | i'm getting a kernel panic error here.. could anybody help me out... |
| 10:18 oz_ | if you can provide an error message or so? |
| 10:19 vineeth | ya.. one min.. |
| 10:20 vineeth | i got a screenshot.. how can i send u that/ |
| 10:21 oz_ | can you maybe type it? |
| 10:21 oz_ | cut'n paste? |
| 10:22 vineeth | ok ok.. |

| 10:27 vineeth | i've just typd the msgs.. thz how it looks |
| 10:29 vineeth | oz_.. if u could accept the screenshot i'm sending u... it will give clear idea... |
| 10:29 oz_ | vineeth: it seems that the nfsroot isn't mounted |
| 10:30 oz_ | vineeth: no, sending screenshots is not professional, somewhat ;) |
| 10:30 oz_ | I don't need it |
| 10:30 vineeth | ok.. |
| 10:30 vineeth | i'm sorry.. |
| 10:31 vineeth | what could be the reasons.. of nfsroot not mounted..? |
| 10:31 vineeth | i'm sure my nfsroot is created correctly.. |
| 10:31 vineeth | the logfiles gave me a correct output.. |
| 10:32 oz_ | what does "showmount -e <yourserverip>" tell you? |
| 10:32 vineeth | `/srv/fai/nfsroot/live/filesystem.dir/boot/vmlinuz-2.6.32-26-generic' -> `/srv/tftp/fai/vmlinuz-2.6.32-26-generic' |

| 10:32 vineeth | Removing `local diversion of /sbin/discover-modprobe to /sbin/discover-modprobe.distrib' |
| 10:32 vineeth | make-fai-nfsroot finished properly. |
| 10:32 vineeth | No diversion `any diversion of /sbin/discover-modprobe', none removed |

| 10:32 vineeth | ...done. |
| 10:32 vineeth | FAI setup finished. |
| 10:33 oz_ | vineeth: no errors during creation? if no, everything is fine with the nfsroot |
| 10:33 oz_ | but you need to check if the nfs on your server is set up correctly |
| 10:33 oz_ | did you read the FAI Guide? |

| 10:35 Mrfai | hi |
| 10:36 Mrfai | NFS is not your problem. |
| 10:37 Mrfai | /scripts/live is inside the initrd/initramfs and at this point NFS and even network setup is not done |
| 10:38 Mrfai | MAybe you are booting the wrong initrd. You must use the initrd from inside the nfsroot. But this is normally done my make-fai-nfsroot |

| 10:42 vineeth | hello oz_... i'm back... |
| 10:43 vineeth | i hope you got the the msg i sent u.. with the output of showmount -e and the logfile... |
| 10:44 oz_ | 11:35 < Mrfai> hi |
| 10:44 oz_ | 11:36 < Mrfai> NFS is not your problem. |
| 10:44 oz_ | 11:37 < Mrfai> /scripts/live is inside the initrd/initramfs and at this point NFS and even network setup is not done |
| 10:44 oz_ | 11:38 < Mrfai> MAybe you are booting the wrong initrd. You must use the initrd from inside the nfsroot. But this is normally done my make-fai-nfsroot |
| 10:45 oz_ | vineeth: did you read the FAI guide? |
| 10:45 vineeth | yes.. i've been searching through that from morning to figureout the problem... |
| 10:47 Mrfai | vineeth: please put your make-fah-nfsroot.log onto paste.debian.net |
| 10:47 vineeth | ok.. sure.. |
| 10:48 vineeth | btw.. i'm doing these setup on ubuntu 10.04.. i hope that's fine.. |
| 10:48 oz_ | \sh will be very happy |
| 10:54 vineeth | i've pasted it to paste.debian.net now... |
| 10:57 vineeth | i hope the client got the kernel and initrd image... |
| 10:58 vineeth | i'm doing it as the first test run.. and have only one kernel and initrd in the nfsroot |
| 11:00 oz_ | vineeth: you shou paste the url in here now.... ;) |
| 11:01 Mrfai | your m-f-n.log looks fine. Even there's one minor warning. But I think we can ignore it. |
| 11:01 vineeth | http://paste.debian.net/101307/ |
| 11:01 Mrfai | does your machine boot now? |
| 11:01 vineeth | yes.. |
| 11:02 vineeth | u mean the warning abt the signature.. will try to fix it once i get one machine installed.. :) |
| 11:03 vineeth | i'm doing it in my laptop as the server and one virtualbox VM as the client.. |
| 11:03 vineeth | once i got it working in the initial stage.. i can start doing it on some other server.. |
| 11:04 Mrfai | ok, so the cannot open /scripts/live error is gone? |
| 11:05 vineeth | ohh no..not yet.. it's just stuck there... |
| 11:05 vineeth | booting from pxe.. and showing kernel panic at the end... |
| 11:08 Mrfai | same error message? |
| 11:08 vineeth | ya... same.. |
| 11:09 vineeth | dhcp server is running.. tftp is ok.. nfs is fine..... |
| 11:09 vineeth | is it some error with the initramfs? |
| 11:09 vineeth | what should i check related to that? |
| 11:10 vineeth | should i/ |
| 11:11 Mrfai | First, how does your pxelinux.cfg/... config file looks like for this client? |
| 11:13 vineeth | cat C0A8761F |
| 11:13 vineeth | # generated by fai-chboot for host demohost with IP 192.168.118.31 |
| 11:13 vineeth | default fai-generated |
| 11:13 vineeth | label fai-generated |
| 11:13 vineeth | kernel vmlinuz-2.6.35-22-generic |
| 11:13 vineeth | append initrd=initrd.img-2.6.35-22-generic ip=dhcp root=/dev/nfs nfsroot=/srv/fai/nfsroot boot=live FAI_FLAGS=verbose,sshd,createvt FAI_ACTION=install |
| 11:13 Mrfai | looks perfect |
| 11:14 Mrfai | ok, now you have to "debug" your initrd. You have to extrace the contents of the initrd, and check if scripts/live is available there. |
| 11:15 Mrfai | use something like this: |
| 11:15 Mrfai | zcat ../initrd.img-2.6.32-5-amd64 | cpio -i |
| 11:15 vineeth | ok |

| 11:19 vineeth | ohhh.. there is no "live" inside the scripts directory..!!!! |
| 11:20 Mrfai | bingo. That's your problem. |
| 11:21 vineeth | ohh... ok ok... |
| 11:22 vineeth | now I see.. thank u very much guys... :) i think i can go a little more ahead now... |
| 11:22 vineeth | i may need ur help again.. |
| 11:25 Mrfai | you can chroot insto your nfsroot and call update-initramfs |
| 11:25 Mrfai | this is what creates or updates your initrd |
| 11:27 vineeth | ok... |
