Directories not persisted across reboots

[Nalum]

I've got mongodb running on minikube but when I minikube stop and then minikube start all the data that was in mongodb is lost. I have the pod mounting a host volume located at /data/mdb. The same thing is happening with elasticsearch.

I am opening this issue at the request of @dlorenc on the slack channel.

Only dirs under /mnt/sda1 will persist. You can either change your hostPath declaration or symink /data to /mnt/sda1/data perhaps?

[dlorenc]

Yeah, we should probably create a simple to use persisted directory (maybe /data?), and document it. Any opinions on which to use?

[jimmidyson]

Host paths are discouraged in general. Wonder if we can set up a persistent volume (even if that is a hostPath PV) via minikube to make this a bit more transparent to users?

[Nalum]

Thanks. I just found this discussion about pv and pvc: #2

@jimmidyson @dlorenc: Is /mnt/sda1 mounted from the host system onto the cluster vm?

[dlorenc]

No, it's just a disk that is persisted across "minikube stop" commands, but not "minikube delete". On some systems "/Users" is automatically mounted in from the host, but not everywhere yet. We're making that more consistent before documenting it.
