Hi Alex,

        Great news.

 At the moment the setup is delayed as we ran into a problem with

I will try to handle this by the end of next week, if that is not
successful I will fallback to local storage which has some
disadvantages as the host is then not able to increase the HA of the
overall platform.

        JFYI - all of the work we do inside the main VM is throw-away work
- we
only are interested in the output of it. Worse - there are tens of GB of
it generated all the time - so mirroring that across a cluster sounds
like it would bring only pain & aggravation =)

        Is there some way we can have the basic VM / OS image on a HA /
mirrored image - but ensure that the scratch data we build, and throw
away repeatedly in really huge bulk doesn't end up just screwing up the
cluster performance ;-) ie. for now local storage sounds just fine to
me ;-)

And to add to that. Actually the whole VM does not need a backup. The
scripts are all in dev-tools and the files are either stored on gimli (the
ones that need backup) or can be downloaded by a script. As Michael
mentioned there are many generated files in the VM and we are generating
each day around 120 GB of data that is deleted after the run.

The whole Vm consists currently of:

* source code for different projects
* test files (backup exists either as part of various bug trackers or on
* the logs (the official and public version is on gimli)
* some stuff for msan and asan builds
* the sripts (are all from the dev-tools repo)

So there is nothing that needs a backup as part of the VM.
