[07:58] <cake> hey, Any quick tips on what i can check when my fai client cant mount the root file system and just drops to busybox shell?
[07:58] <cake> i had this working on a 32bit server, but moved the install to a 64bit box. And now the pxe booted clients cannot mount the root fs

[09:11] <stockholm> cake: read the file /log 
[09:12] <stockholm> cake: it logs stuff there
[09:29] <cake>  /log ? inside busybox? there is no such thing
[09:29] <cake> there might be a dns problem
[09:29] <cake> nslookup doesnt work
[09:32] ErKa (~keryell@195.115.75.222) joined #fai.
[09:39] <stockholm> not inside busybox, inside debian-live initramfs
[09:39] <stockholm> err... initramfs
[09:41] <cake> stockholm: yes
[09:41] <cake> stockholm: there is no /log there
[09:41] <stockholm> ok
[09:41] <cake> wait
[09:41] <oz_> cake: can you use e.g. wget instaed of nslookup?
[09:41] <cake> live.log ?
[09:42] <stockholm> its in the /
[09:42] <stockholm> a file
[09:42] <stockholm> with a very obvious log name
[09:42] <cake> oz_: nope, nothing which needs dns
[09:42] <cake> nslookup wget ping
[09:42] <cake> etc
[09:43] <cake> cat /live.log
[09:43] <cake> gives me:
[09:43] <oz_> no network at all?
[09:43] <oz_> or just DNS
[09:43] <oz_> ?
[09:43] <cake> Begin: Trying nfsmount -o nolock -o ro ftpt/fai-server-ip:/src/fai/nfsroot /live/image ...
[09:43] <cake> rpc failed: 2
[09:43] <cake> like 20 times
[09:43] <cake> Done
[09:44] <cake> Unabel to find a live file system on the network
[09:44] <cake> so i think it might be dns trouble
[09:44] <cake> I can see there is traffic between the fai server and the booted client using tcpdump
[09:44] <oz_> "ftpt/fai-server-ip:/src/fai/nfsroot" looks weird.
[09:45] <cake> oz_: just scrambled it abit
[09:45] <cake> lets say it said 192.168.1.10:/srv/fai/nfsroot
[09:45] <cake> oz_: to answer your q, the network is working
[09:46] <cake> i can ping the dnsservers, the gateway, the fai server - just not do dns lookups it seems
[09:46] <cake> :s
[09:46] <cake> brb lunch time :)
[09:46] <oz_> but that should work then, if you use ip adresses
[09:46] <stockholm> cake: try it with an ip?
[09:46] <stockholm> see if it works then?
[09:46] <oz_> stockholm: ^5 :)
[09:46] <stockholm> :-)
[09:52] fai-guy (~fai-guy@p4FC235F5.dip0.t-ipconnect.de) left irc: Quit: leaving
[10:00] <cake> i did try with an ip
[10:01] <cake> i still get rcp failed: 2
[10:02] <stockholm> cake: can you tcpdump on the network?
[10:03] <cake> sure
[10:03] <stockholm> check if you see any packages
[10:03] <cake> i do see plenty of packages
[10:04] <cake> but there is a problem with the mount somehow as it returns rpc failed: 2
[10:04] <cake> i thought portmap
[10:04] <cake> but no
[10:04] <cake> it runs
[10:05] <cake> i can mount the share from other places on the network
[10:05] <stockholm> "share"?
[10:05] <cake> the nfsroot share
[10:06] <cake> if i run the same command which fai uses to try and mount the nfsroot - it works from other servers
[10:06] <stockholm> i dont call nfs stuff share. i thought that was windows terminology :-)
[10:06] <cake> hehe
[10:06] <cake> ubuntu calls it shares
[10:06] <cake> anyway
[10:07] <stockholm> so when you are on the prompt on the intiramdisk after it fails to mount 
[10:07] <stockholm> can you mount the nfs dir then?
[10:07] <cake> nope
[10:07] <cake> same error as in the log
[10:07] <cake> rpc failed: 2
[10:08] <stockholm> then i guess your configuration is messed up
[10:08] <stockholm> do you have several interfaces on that box?
[10:08] <cake> yes, but i can ping the ip address
[10:08] <cake> so there is connectivity
[10:09] <cake> just dns doesnt work
[10:09] <cake> im not really sure how dns works in busybox as there is no /etc/resolv.conf or /etc/hosts
[10:09] <stockholm> if it just dns then it would work with the ip
[10:10] <cake> but the dhcp server passes the domain-name-server arguments so..
[10:10] <cake> maybe i should try to create the initrd again
[10:10] <stockholm> did you put an ip there, too?
[10:10] <cake> :)
[10:10] <cake> there is nothing wrong with the dhcp server
[10:11] <cake> i ported this faiserver install from 32bit to 64bit
[10:11] <cake> the configuration isnt changed
[10:11] <cake> only thing that is changed is what kernel and initrd is loaded on boot
[10:11] <cake> so i guess there is something wrong with the initrd
[10:12] <stockholm> dude, if you suspect that your dns is not working then either fix it or try to work around it or isolate the problem
[10:12] <stockholm> one way to isolate the problem is to use ips instead of names
[10:12] <stockholm> EVEN IN THE DHCP NEXT SERVER!!!!
[10:13] <cake> which is what i have
[10:13] <cake> i do know that the dns does not work from the initramfs prompt
[10:14] <cake> i did try to work around it with using the ipaddress in both the dhcp config and the fai config
[10:14] <stockholm> then something more is broken.
[10:14] <stockholm> not just dns
[10:15] <stockholm> like the exports or netgroups on the nfs server
[10:15] <cake> which is why i suspect something might be wrong with the initrd
[10:16] <cake> the nfs server is working perfectly, i can mount the /srv/fai/nfsroot nfsshare from other hosts in the network
[10:16] <cake> which is weird
[10:18] <stockholm> the initramdisk could be broken, yes
[10:24] <cake> how can i recreate it?
[10:43] <ichbins> so jungs feierabend bis mojen ;)
[10:44] ichbins (~hfjkef@dennisr.inf.bi.ruhr-uni-bochum.de) left irc: 
[10:54] <cake> stockholm: do i need to specify somewhere that this is supposed to be a amd64 nfsroot?

[15:50] <cake> stockholm: i solved the problem - there was in fact a problem with that specific nfs server, allthough i could mount the dir on other servers it wouldnt let me mount it from busybox
[15:52] <cake> anyway, can anyone tell me where i can specify what domainname the installed host should have?
[15:52] <cake> right now i have 192.168.0.10 host. host
[15:52] <cake> in my etc/hosts
