FileNotFoundError: [Errno 2] No such file or directory: while deleting the minidcos vagrant cluster - mesos

Question

I have created local minidcos vagrant cluster using below command.
$ sudo minidcos vagrant create ./dcos_generate_config.sh --agents 0
The above command is not successful. It is failed abruptly due to No space left on device.
when I list the cluster I see the cluster exists.
$ sudo minidcos vagrant list
default
I'm not able to access the cluster using sudo minidcos vagrant web. I get the same error when I tried to destroy the cluster as below -
$ sudo minidcos vagrant destroy

How can I successfully delete the cluster?

Answer 1

The issue here was that the workspace directory was deleted, and yet the VMs were still detected.
The workspace is configurable as per the documentation.
This could happen because the workspace directory is somehow deleted while the VMs are running, but it also happens when the host is shut down (assuming the default workspace temporary directory is used).
The behaviour is now changed as of minidcos version 2019.04.08.1.
In particular, minidcos vagrant list no longer lists VMs which are not in the running state.
There is also a new minidcos vagrant clean command which cleans all VMs and leftover VMs.
