Right, this is something, we from Linux for zSeries desperately need.
In Böblingen we currently only use cross lcrash on an intel dump server,
which can debug s390 and s390x dumps.
This is an important reason, why crash currently is no option for us.
I know I'm setting myself up for flames here, but
why not use NFS? Prior to writing this, I was just
looking at an x86_64 vmcore file stored on, and
NFS-mounted from, an x86 netdump server, and have
done that many times.
One reason is, that zSeries servers are quite expensive and
it is much cheaper to use intel based machines for debugging
dumps.
Another reason is, that you only need one machine,
where dumps of all supported architectures are stored
and where the debugging is done. All people who want to
debug dumps just logon to that system. This is
especially useful for bigger service organizations,
which support different platforms.
A third reason is that some people want to
work offline. Therefore they just copy the dump to
their notebooks.
