Hey folks - thought I'd check and see if anyone has ever tried to use ephemeral (tmpfs / ramfs based) boot disks for Ceph nodes?

croit.io does that quite succesfully I believe [1].

Same here at ungleich, all our ceph nodes with the exception of the monitors are PXE booted. And as a matter of fact, 90% of them even netboot via IPv6 only using ipxe.

From an operational point of view I believe there is not much difference to a regular setup, besides you'll need to have a trigger in place to configure the servers when rebooting, as the boot image itself is rather empty in our case.

Best regards,
