Unable to start experiment with a reservation

[Jianshen Liu]

Dear Admin,

I have two machines reserved for an experiment, but I'm encountering an issue starting the process. Could you please look into this to see if there are any underlying problems?  

Thanks,

Jianshen

I put two machine back in service that were likely preventing your experiment
from starting.

Thanks for helping! Is it possible to add another node to my existing experiment here?

You cannot add a node to your particular experiment as it appears it was created with the old,

unsupported GUI. It is also highly unlikely that there would be another "r7525" node available.

If your profile is created with geni-lib, then there is a limited ability to change a running experiment.

Specifically, you can modify characteristics that are parameters in the profile. For example, if you

have an experiment where "number of nodes" is a parameter (like the default "small-lan" profile),

then you can modify that parameter to get more or less nodes. There are still plenty of caveats 

however, even for something as simple as adding another node: there might not be an available

node, your existing topology might make it impossible to fit a new node in, the existence of local

or remote blockstores might cause problems, your specified OS image might not work on the node,

and others.

I see. I appreciate the detailed response.

Thanks!
