Mounting of PSC's lustre-wan filesystem (kerberos, cross-realm) by SDSC now successful.
We used the same lustre-version. We'll refine and continue to explore other features.

Note that lustre 1.9 is an unsupported alpha branch, and there is
absolutely no guarantee nor attempt at keeping interoperability
between builds at this stage. There is actually a considerable amount
of change to the wire protocol underway in order to make it interoperate
with the 1.8.0 release (which is also getting similar change before
release), and to be more performant in the final 2.0 release.
It is great that you are testing this release, but please always ensure
that the same version of code is being run on both the client and server
at this stage. As we get closer to the 2.0 final release the wire
protocol changes will be finished.
