I set up an NFS-root, PXE-boot cluster about a year ago. I can try to |
| 9 |
put my notes together into something usable as a doc, if you'd like. |
| 10 |
|
| 11 |
The basic idea I used was to maintain a couple of ROOT=/foo environments |
| 12 |
on the master server: one for the NFS root, and one smaller one with |
| 13 |
just busybox and a kernel to create an initrd for each node. |
| 14 |
|
| 15 |
The ROOT approach is far superior to what's promoted in the NFS root |
| 16 |
Gentoo doc, because it allows for a maintainable and differentiated node |
| 17 |
system rather than just copying straight from the master's root fs. |
| 18 |
|
| 19 |
I then booted to the kernel+initrd with an interesting setup: |
| 20 |
PXE-capable Etherboot on a floppy in each node (required a development |
| 21 |
version of Etherboot at the time), because I didn't have PXE-capable |
| 22 |
Ethernet cards, launched pxelinux on the server (part of isolinux), |
| 23 |
which served as a HW-address-specific bootloader so it was possible to |
| 24 |
have different roles for nodes. With a little symlinking I was able to |
| 25 |
just have one pxelinux config file per role. |

Thanks, |
