| 09:58 laurentl | i have configured the pxe boot to be in a vlan |
| 09:59 laurentl | i load the pxlinux.0 |
| 09:59 laurentl | but when it runs the install kernel |
| 09:59 laurentl | after loading the ethernet driver it start another dhcp request |
| 09:59 laurentl | and configured the ethernet interface |
| 10:00 laurentl | but how i could do a vlan conf at this moment ? |
| 10:02 laurentl | i need to setup the interface in a vlan before the dhcp request |
| 10:02 Mrfai | I think you should ask the initramfs people, if this is possible |
| 10:04 laurentl | Mrfai: ok |
| 10:06 laurentl | Mrfai: vlan config could not be done in the fai modified rcS script ? |
| 10:07 Mrfai | I think it's to late, since the initramfs tools do the nfs mount before any FAI script is started |
| 10:07 laurentl | Mrfai: yes right |
| 10:15 laurentl | Mrfai: is there an irc channel for initramfs ? |
| 10:16 Mrfai | not sute. maybe mikap can answer it |

| 11:41 mikap | laurentl: \sh does vlan config IIRC |
| 11:41 mikap | \sh: ^^^ can you help out here? |
| 11:41 laurentl | cool :) |
| 11:42 \sh | mikap: sure |
| 11:42 \sh | what's the problem? |
| 11:42 laurentl | when initramfs mount the network interface |
| 11:42 laurentl | i need it mount a vlan interface |
| 11:42 \sh | ouch... |
| 11:43 \sh | I wonder if this is really possible |
| 11:43 laurentl | i extract ma initrd file |
| 11:43 \sh | no... |
| 11:43 laurentl | a start looking at the scripts |
| 11:43 \sh | you need to check the /usr/share/initramfs-tools/ scripts if it's possible |
| 11:43 \sh | but just a guess now |
| 11:43 laurentl | i saw a 23networking script |
| 11:44 laurentl | there is some ipconfig command |
| 11:44 \sh | 1. install the 8021q module inside the initramfs |
| 11:44 \sh | (do that via /etc/initramfs-tools/modules file) |
| 11:44 mikap | vlan package doesn't provide any i-t scripts/hooks |
| 11:44 \sh | mikap: yes...but you need it anyways |
| 11:45 \sh | laurentl: I think you want to do the nfs mount via the vlan interface, right? |
| 11:45 laurentl | yep |
| 11:45 laurentl | yes |
| 11:45 \sh | this is totally wrong :) |
| 11:45 laurentl | the conf on my switch is a trunk |
| 11:45 \sh | I mean doing the nfsmount during fai install via vlan is totally wrong design in your network :) |
| 11:46 \sh | I know :) |
| 11:46 \sh | but you should think about having a native with it, for untagged ip packages |
| 11:46 laurentl | in fact i use the ipmitool to redirect the output of the console |
| 11:46 laurentl | and i need to have tje ipmi vlan and the fai vlan |
| 11:46 \sh | cisco switch? |
| 11:46 laurentl | on the juniper port scitch |
| 11:47 \sh | best practice from our DC is: 1. configure your switch port as trunk, for tagged pakets, and have a native trunk vlan configured for untagged pakets |
| 11:48 laurentl | hum right |
| 11:48 \sh | during FAI install you do your network stuff on the native vlan , and then you install your production system with vlan interfaces etc. and after reboot it's using the trunk configuration |
| 11:48 laurentl | i try this |
| 11:48 \sh | ipmi is totally useless during installation...if you have the possibility use HW with ILO or other remote insight boards |
| 11:49 mikap | \sh: sure, but if vlan should be supported within initramfs the package should provide the according i-t scripts, that was my point :) |
| 11:49 \sh | mikap: the problem again here is ipconfig, vlan interfaces are virtual and ipconfig + kernel params are only using hw nic decies |
| 11:49 \sh | devices even |
| 11:49 mikap | yes |
| 11:50 \sh | because when you do your PXE boot, I never saw something like "configure vlan id for pxe interface" |
| 11:50 laurentl | i can configure the boot pxe in a vlan |
| 11:51 laurentl | on a dell r410 server |
| 11:51 \sh | laurentl: yes, but then you have at least an access port or a native trunk config on your port |
| 11:51 laurentl | no |
| 11:51 \sh | pxe does untagged pakets first |
| 11:51 laurentl | only the fai and ipmi vlan tag |
| 11:52 laurentl | no native |
| 11:52 \sh | laurentl: trunk means the os or the system is doing the tagging, the switch only checks for the allowed vlans on the trunk |
| 11:52 \sh | how do you configure your vlan id on the NIC in the bios? |
| 11:53 \sh | HP can't do that, IBM can't do it..and I wonder if dell machines can do such things |
| 11:53 laurentl | on the dell server |
| 11:53 laurentl | i can do a ctrl+S |
| 11:53 laurentl | it is not in the bios |
| 11:53 laurentl | and edit the lan card parameter |
| 11:54 \sh | this means you have a manual step in your provisioning of the server, you want to avoid that |
| 11:54 laurentl | my problem is after that |
| 11:54 laurentl | when i configured the server like this |
| 11:54 laurentl | i can load the pxlinux.0 kernel by tftp |
| 11:54 \sh | yes..because kernel + initramfs are only using (right now) a HW nic interface |
| 11:54 laurentl | but after when it load the fai kernel |
| 11:55 laurentl | and start to execute the initramfs tool |
| 11:55 laurentl | it does a dhcp request |
| 11:55 \sh | the pxe loader gives back "eth0" or "eth1" but not vlan id infos with it |
| 11:55 laurentl | but not in a vlan configuration |
| 11:55 \sh | the pakets then are untagged...because the kernel doesn't know how to tag them, because the whole vlan config for the hw nic is missing from initramfs |
| 12:00 laurentl | doesnt work with the native vlan specified on the switch |
| 12:00 laurentl | :/ |
| 12:01 laurentl | it is normal the return packet are not tagged anymore |
| 12:01 laurentl | so there is not solution |
| 12:01 laurentl | i must wait the vlan support in the initramfs |
| 12:04 \sh | laurentl: yes, you need to get rid of your NIC parameter which you set on the machine now |
| 12:04 laurentl | yes but if i do not use this i cant get my console by ipmi |
| 12:04 \sh | laurentl: when you set the vlan id in your hw nic settings, then you have to remove them...native only works for untagged pakets, but you are tagging them now hw wise via the server config |
| 12:04 laurentl | and cant use the pxe menu |
| 12:05 \sh | dell has no real remote insight? only impi? |
| 12:05 laurentl | i must use a full automatic install |
| 12:05 laurentl | there are drac |
| 12:05 laurentl | but dont know how it works |
| 12:05 \sh | like HPs ILO? |
| 12:05 laurentl | yes |
| 12:06 \sh | another reason to not use dell servers ;) |
| 12:06 \sh | I mean you can hack vlan support into your initramfs but then you need to tweak the kernel param stuff of fai, too |
| 12:06 \sh | and I really wonder if ipconfig can deal with vlan interfaces |
| 12:07 laurentl | for the fai kernel i just need to add |
| 12:07 laurentl | live-getty console=tty0 console=ttyS1,115200n8 |
| 12:07 laurentl | it is not a problem |
| 12:07 laurentl | hum no i understand |
| 12:08 laurentl | you mean to retrieve the vlan parameter specified in the kernel command |
| 12:08 \sh | yes... |
| 12:08 laurentl | ok |
| 12:08 \sh | the vlan tool adds a vlan id tag info to the hw interfaces (eth0 e.g.) but then it tries to rename the interface, too, so you can't boot from eth0 but from e.g. vlan100 |
| 12:08 laurentl | i saw this post |
| 12:09 laurentl | http://kerneltrap.org/mailarchive/linux-netdev/2010/2/8/6268717/thread |
| 12:09 laurentl | but not sur to understand well |
| 12:09 laurentl | it seem a guy wrote a patch to add vlan support |
| 12:10 laurentl | maybe i just need to add the vconfig binary |
| 12:11 laurentl | and add some vconfig command into the networking script |
| 12:14 laurentl | is there any irc channel with initramfs dev ? |
| 12:16 \sh | -> mikap ;) |
| 12:20 laurentl | ok :) |
| 12:20 laurentl | mikap: you need how many money to add vlan support in initramfs ? :D |
