| 11:17 svarrette | Hello everybody, I have a short question regarding FAI: my cluster nodes now have a new network interface (10G) bound to eth2 and I would like to know how to pass the info to FAI so it populates correctly /etc/network/interfaces. I noticed this files starts with a "# generated by FAI" but couldn't find in which script and I want to avoid to manually change it to add "auto lo eth0 eth2" and "iface eth2 inet dhcp" inside a script. Any hint? Related question |
| 11:17 svarrette | if I want to statically assign the address for this interface (i.e. to make a generic template instanced for each node)? |

| 12:52 jes-o-mat | hi |
| 12:52 jes-o-mat | I'm trying to setup an faiserver - somehow my target always get's configured with hostnamen 'host' |
| 12:53 Mrfai | have a look at the log file of make-fai-nfsroot |
| 12:54 jes-o-mat | inside dhcpd.conf I give him a static lease |
| 12:54 jes-o-mat | I always though the target takes the hostname from the dhcp/hosts configuration? |
| 12:55 jes-o-mat | can it be 'cause the target and faiserver are using different dns servers? |
| 13:04 jes-o-mat | https://jesusch.de/~jesusch/tmp/make-fai-nfsroot.log |
| 13:05 jes-o-mat | https://jesusch.de/~jesusch/tmp/error.log |
| 13:05 jes-o-mat | the make-fai-nfsroot.log seems fine to me |

| 13:35 jes-o-mat | Mrfai: any ideas? |
| 13:57 Mrfai | yes, make-fai-nfsroot.log lokks good. What about fai.log and boot.log |
| 14:19 jes-o-mat | https://jesusch.de/~jesusch/tmp/fai.log.txt |
| 14:19 jes-o-mat | https://jesusch.de/~jesusch/tmp/boot.log |
| 14:23 jes-o-mat | the first boot.log lines seem confusing to me |
| 14:23 jes-o-mat | but it's logical as the nfsroot ist read-only |
| 15:25 jes-o-mat | Mrfai: you see anything in these logs? |
| 15:25 jes-o-mat | dhcpd.conf: host fax01 {hardware ethernet 00:22:19:54:01:86;fixed-address fax01; |
| 15:26 jes-o-mat | etc/hosts: 192.168.86.41 fax01 |
| 15:26 jes-o-mat | /srv/fai/config/class/50-host-classes: fax*) \n echo "FAIBASE FAX";; |
| 15:27 jes-o-mat | there are no definitions for FAX up to now |

| 22:22 mgoetze | jes-o-mat: you probably want to add "option host-name fax01" to your dhcpd.conf |
| 23:35 uchimata | At the moment, I'm not really sure how the nfs mount on the client side is done: Which IP/host is used to mount the nfsroot? Is it "hard-coded" into the pxe-booted kernel? |
| 23:41 BlindBunny | uchimata: as long as you don't configure the system otherwise, the DHCP server's address is used to mount the nfsroot from, I think |
| 23:46 uchimata | BlindBunny: ah ok..... so that's bad since there is a dedicated dns server..... |
| 23:47 uchimata | which also provides the tftp-server, but the install/nfs server is a different host |
| 23:47 uchimata | so is there a way to influence this behaviour? |
| 23:48 BlindBunny | I think you should find an nfsroot= statement in your pxe config files |
| 23:49 BlindBunny | It should be possible to just prefix the path with the host name/IP address of your NFS server |
| 23:49 BlindBunny | so it reads nfsroot=<NFS server>:<path> |
| 23:49 uchimata | BlindBunny: ah, that sounds great :) |
| 23:49 uchimata | right, just saw it |
| 23:49 uchimata | I'll try that tomorrow.... you made my day :) |
| 23:50 BlindBunny | And I believe that fai-chboot actually sets that information from one of the /etc/fai/ config files |
| 23:51 uchimata | BlindBunny: I just found the url for the config-dir |
| 23:53 uchimata | BlindBunny: *in the man fai-chboot |
