[Errno 28] No space left on device when trying to install a package with pip inside a VM

[shadeofblue]

steps to reproduce:

1. start a cluster normally with ray up golem-cluster.dev.yaml
2. ray attach golem-cluster.dev.yaml
3. pip install numba

ERROR: Could not install packages due to an OSError: [Errno 28] No space left on device

suggested solution: we should change the VM image to use a VOLUME and ensure that pip is configured to keep at least the temporary files but preferably all the installed packages on an external volume

Let's talk @shadeofblue - with Kamil we didn't know about this VOLUMES enough

[shadeofblue]

okay, so there are three facets to this issue:

• when running any payloads on ray on golem, if there are artifacts written to the current working directory, they'll pretty quickly fill up the remaining space
• when one installs packages inside the VM, the downloaded package files and then packages themselves also take up space on the current filesystem, which also means that you cannot install anything itself larger than the available space
• when anything happens to the ray node on the VM, to pull the logs we now need to log through SSH but it would be easier to just snatch those logs from the machine with regular exescript transfers - but afair/k, they require the files to be transferred residing on a volume...

so, it all boils down to the fact that we need to rework the images so that they use VOLUMES appropriately to alleviate the above issues...
