Diskless boot

[Congyu Liu]

Hello,

I’d like to configure my CloudLab nodes to boot without using any local disks, so that I can reserve all local NVMe SSDs for direct use in experiments. I’m wondering whether CloudLab interfaces currently supports some workarounds for this (e.g., fully diskless PXE + NFS); if so, are there recommended or supported approaches to configure this in a profile.

Any guidance or suggestions would be greatly appreciated.

Best,

Congyu

We do not have any sort of support for diskless booting.

You can put nodes in the "Recovery MFS" which is a RAM-based system,
but it is a much reduced Linux (busybox-based) and not particularly
extensible to a more full-featured environment. It also eats a lot of RAM,
which I suspect is important to you as well.

Do you want high-capacity or a large number of disks or both?
