[12:45] <Lebowski1> Hello,
[12:46] <Lebowski1> i've some problem while booting the client, i get the error message  Kernel panic - not syncing: VFS: Unable to mount root fs on > unknown-block (2,0)  Some know these
[12:47] <Lebowski1> The exports file contains this lines; /srv/fai/config 10.0.2.0/255.255.254.0(async,ro,no_subtree_check) 
[12:47] <Lebowski1> /srv/fai/nfsroot 10.0.2.0/255.255.254.0(async,ro,no_subtree_check,no_root_squash) 10.0.2.100(ro,async)
[13:06] <BlindBunny> Lebowski1: can you successfully mount the NFS root fs when you boot, e.g. grml or knoppix on the client?
[13:08] <Lebowski1> I tried mounting on another PC with ubuntu. It still works
[13:16] <Lebowski1> I booted the client with ubuntu live-cd and tried: ubuntu@ubuntu:~$ sudo mount 10.0.2.2:/srv/fai/nfsroot/ /mnt/asd/ with this result: mount: wrong fs type, bad option, bad superblock on tjener:/srv/fai/nfsroot/,
[13:16] <Lebowski1>        missing codepage or helper program, or other error
[13:16] <Lebowski1>        (for several filesystems (e.g. nfs, cifs) you might
[13:16] <Lebowski1>        need a /sbin/mount.<type> helper program)
[13:16] <Lebowski1>        In some cases useful info is found in syslog - try
[13:16] <Lebowski1>        dmesg | tail  or so
[13:17] <BlindBunny> Lebowski1: what does the kernel command line look like that you boot the client with? I mean for the FAI installation?
[13:18] <BlindBunny> Lebowski1: not sure whether that might actually be a different problem
[13:19] <BlindBunny> Lebowski1: sorry, bbl (lunch)
[13:20] <Lebowski1> Do you mean this line (in pxelinux.cfg/<ip-in-hex>) kernel vmlinuz-install
[13:58] <BlindBunny> there should be an 'append' line, too
[13:59] <Lebowski1> Hope you enyoyed your lunch. Mounting nfs on client succeed while booting with ubunu-live. I forgot to install nfs-common. So, I think its a problem in the fai-configuration
[13:59] <Lebowski1> The append line is: append ip=dhcp FAI_ACTION=install root=/dev/nfs nfsroot=/srv/fai/nfsroot,v3,tcp,rsize=32768,wsize=32768  FAI_FLAGS=verbose,sshd,reboot
[13:59] <Lebowski1> What is the meaning of root=dev/nfs/  there is no /dev/nfs
[14:00] <BlindBunny> try adding the statement 'boot=live' to the append line
[14:01] <BlindBunny> the device /dev/nfs does not exist but it tells the initial ram disk to boot from NFS
[14:02] <Lebowski1> No changes, i get the same error
[14:04] <BlindBunny> hrm
[14:06] <BlindBunny> can you tell from the console messages whether the client gets an IP-address via DHCP?
[14:08] <BlindBunny> hang on
[14:08] <BlindBunny> so you do boot via PXE, right?
[14:09] <Lebowski1> Yes he get the adress 10.0.2.50  , there is an entry in the dhcp.conf # statische Vergabe 
[14:09] <Lebowski1>     host static00 {
[14:09] <Lebowski1>        hardware ethernet 00:90:F5:67:64:3F;
[14:09] <Lebowski1>        fixed-address static00;
[14:09] <Lebowski1>     }
[14:09] <Lebowski1> yes, i boot via pxe
[14:09] <BlindBunny> and which FAI version do you use?
[14:10] <Lebowski1> how to find out
[14:10] <Lebowski1> ?
[14:11] <BlindBunny> fai --help on your server
[14:12] <Lebowski1> fai FAI 3.1.8, 13 Mar 2007
[14:13] <BlindBunny> have you created the PXE config with the chboot command?
[14:14] <Lebowski1> Ja
[14:14] <Lebowski1> Yes, but i'll trie agein
[14:15] <BlindBunny> ok, no, then it should be alright
[14:16] <BlindBunny> no, sorry, then I'm out of stupid questions
[14:17] <Lebowski1> Ok, thanks anyhow
[14:19] <BlindBunny> you might want to try the latest FAI version
[14:20] <BlindBunny> it uses a different booting method which is fairly reliable
[14:20] <BlindBunny> see http://faiwiki.informatik.uni-koeln.de/index.php/Main_Page#getting_FAI
[14:20] <BlindBunny> cu - I'm off
