Re: [PLUG] Add an HDD to a diskless cluster node?

[David Coulson <david@davidcoulson.net>]

Either.

1) The system doesn't have the correct kernel module loaded for the disk 
controller
2) The disks are attached to a RAID controller and you did not define an 
array
3) You are using fdisk with the wrong device path

Send the output of lsmod, lspci and dmesg please.
