 Ok, as you said, *can* mean to an OST. Let's suppose a host is running
the OST and the client, but it has a local (not managed by Lustre) swap.
Let's say Lustre is used to provide access to a large dataset on a SAN,
but the system itself is stored on local disks on each node.
In this case, if the client is experiencing memory pressure, it will
just flush to the local disk, and it will continue doing so until there
is swap available... or not?

Am I missing something? :)

Thanks for your answers!
