"No space left on device": but how much space do I have, and how much do I need to clear to get it to work?

[sanjayankur31]

I'm trying to import a NeuroML model into NetPyNE and am apparently running out of space on the device:

OSError: [Errno 28] No space left on device

This is fine. The issue is: as a user, I want to know what I should do now to work around this. But, I don't know:

• have I used up my workspace disk space quota? If yes, I should be informed
• if this is some other temporary space that is not part of my quota, what should I do?

Additional question: as a user, how do I figure out what version of OSBv2 I'm using? What release is it?

[filippomc]

There is no currently a way for an end user to know the version. Does it matter (I mean apart for us testing)?

[sanjayankur31]

It's not very important for end-users at the moment. Maybe more important when we do the federated deployments etc. later.
