BTW, how can I tell if the diskless image is actually being created? I looked on the core and can't find any running process that would indicate the MD's image is being created.
The script Diskless_Setup.sh creates the image. If that is running, the Diskless MD filesystems are being created. If you don't see it, it's not happening. It creates the /usr/pluto/diskless directory and MD subdirectory.
If this is not the case for you, here's how it all works:
1. New MD PXE boots default boot image.
2. Default boot image connects to the Core and tells it to create a new MD device.
3. Default boot image displays "announced ourselves to the router" and waits for messages from the Core.
4. Core creates a MD device (check your device tree)
5. Core allocates IP address to new MD, tells new MD about it (you get "Allocated permanent IP" message on MD).
6. Core runs Diskless_Setup.sh, tells new MD about it (you get "Running Diskless_Setup.sh" message on MD).
7. When Diskless_Setup.sh finishes, Core tells MD about it. If it fails, the MD will display "Diskless_Setup.sh failed" message. If it succeeds, you'll get a success message and the Core will also tell the MD to reboot.
8. MD reboots into its new filesystem.
At no point should Diskless_Setup.sh die without the MD getting a message (error or success).
If you don't have the MD device in your tree after the router announcement, you have a different problem. If you do have the device in the tree, and MD says Diskless_Setup is running, but you don't see Diskless_Setup on the core, run /usr/pluto/bin/Diskless_Setup.sh yourself on the Core and see what's happening.
