I just got given 3 Cobalt RaQ 550's, only catch was they had no HDD's in them.
Problem, everything i've tried won't work. Does anyone have a link to a guide or can anyone supply me with a step by step how to, to get one of these things up and running?
I have got some seagate 40GB drives that fit in the racks fine, i have tried everything from Rackstar to CentOS/Bluequartz to get these things up and running but everything i do results in a Kernel Panic being displayed on the rack LCD.
I need a step by step "this is how to get it working" guide. Don't omit even the tiniest detail. thanks.
1) Raq550s use EXT3 filesystem, not XFS. This is most likely to be your problem.
2) In order to install CentOS+BlueQuartz on a Raq, you need to have an up-to-date ROM. I was under the impression that all the 550s had them, but might be wrong (I don't have any 550s). So, check to ROM version (it gets printed out during the first part of the boot sequence). The latest and best ROM is cobalt-2.10.3-ext3-2M-flat.rom but bear in mind that, while you can install a ROM over the serial port, it is much easier doing it from a running system. You may want to first install the original 550 OS, update the ROM, then reinstall CentOS+BQ;
3) The "md" disk tpe indicates you have a RAID setup -- assume this was wahat you intended. Be sure your installer knows this, and there is a possibility that you have a bad block on the primary disk -- you might try to swap them and reinstall;
4) Since you are ighly motivated to get these working, you might want to consider paying for the SrongBolt installer -- it's about US$50 and seems to work very well. It works just like the original 550 restore disk. I am not affiliated with them but have used it on a Raq4 and had a good experience. Find it at www.osoffice.co.uk;
Gunzip it and make a cd... you can then follow the standard restore process and you should be up in about 20 minutes... There will most likley be updates you need to do when your done... just don't do the last sendmail update. it's broke.
Cool, thx for the help guys i eventually got them up an running using the OS restore, now it works but is there a way to set the 2nd eth interface to accept an IP address via DHCP or is it static all the way?
* You will be happier in the long run if you now upgrade your OS to CentOS+BlueQuartz, as these are being actively maintained, whereas the 550 OS is not;
* For DHCP, look at dhclient(8), dhclient.conf(5), and related information. The 550 manual says:
When the Cobalt RaQ is powering up, it checks to see whether a
DHCP server is present on the network. If there’s a functioning
DHCP server that’s set up to serve leased IP addresses, then the
Cobalt RaQ configures itself automatically. If the network
information can be configured automatically, then the LCD
displays the Cobalt RaQ’s assigned IP Address upon completion
of the boot process.
It seems the RaQ550 won't accept IP addresses on any Interface via DHCP, even when its booting. I tried both but it just won't do it.
I wanted to set 1 of the racks up as a dedicated Firewall/router between the internet and my own network, i.e Cable Modem directly into ETH1 and the Local LAN on ETH0, probelm is, without a router inbetween the cable modem and ETH1 it won't take the IP address given by the modem, and it seems the cable modem i have (Motorola SB5100) won't work if i set the IP on the raq inteface statically.
so i may do the ROM upgrade and install CentOS if this will allow DHCP on any of the eth interfaces.
