Just check if you have enabled virtual media.  You can disable that. Once disabled the first
disk will be sda in Linux and your installation will go fine.   I was able to clear the problem
in the same way.

In  /tftpboot/ubuntu-12.04/net_seed file ( line 109 )  I see that /dev/sda is
hardcoded.

Randy,
The problem is still there.

Surya,
I'm not sure why sdb is coming up as primary disk.  This is a poweredge 2950 III.

Why is your primary disk showing up as sdb when you have no other disks in the system?

can you check what is eating up sda? what is the hardware model?

I have since changed the raid controller to 1 disk only.  /proc/partitions shows:  http://imgur.com/X4jYL

Hi,

Looking at what you set up, I see the RAID Controller reporting 6 Virtual Disks.  Did you configure one as the Primary Boot Volume in the RAID Controller BIOS?

Was not replying to all... Oops.  Here is my reply:

Here is the sequence of events...

1.     Power on server
2.     Server PXE boots
3.     Registers with the admin node
4.     I allocate the node.  I don't do anything but put in a name and a description.  No RAID config.
5.     The node continues loading some stuff then reboots.
6.     It PXE boots again.
7.     After it loads the system utilities, it bombs out with this error:  http://i.imgur.com/sOpkT.jpg
I've also recorded a screencast of this failure from the first PXE boot through.  You can see it here:  http://www.youtube.com/watch?v=hhQMUUgZc0U

Tim,

The normal flow shuld be an initial PXE boot of a CentOS image ('sledgehammer), at which point the node should wait to be be allocated before continuing.

Are the nodes being discovered by Crowbar, and the errors occur after allocation , or do the errors occur before the node is discovered?
