| 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 |
| 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 | :-) |
| 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 ;) |

| 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 |
