Hello,
I experimented with swap on lustre in as many ways as possible (without
touching the code), and had the shortest path possible to no avail. The code
is not able to handle it at all, and the system always hung.
Without serious code rewrites, this isn't going to work for you.

Hi,
some time ago, I was asking whether it is possible to use Lustre Client and
Server on a single node, i.e., if I can mount Lustre FS on an OSD node. The
anwser was NO as there were some issues with cache pressure and deadlocks.
Is this still a problem or Lustre 2.x client and server can
Andreas,
Thanks for you reply. It was very helpful. See my responses, below.
I am in the process of porting Lustre client 1.8.4 to a recent
kernel,
2.6.38.8.

Since you are considering other options, I would recommend NBD swap for this
type of minimal swapping application. Look at the Linux Terminal Server
Project (LTSP) implementation using nbdswapd, a simple inetd-driven script that
creates and exports NBD swap spaces. We have been using this
