Resolved: Problem was I wasn’t including the / when trying to cd into shared folder. cd /shared/.
Also, it turns out shared folder just doesn’t appear when ls-ing from root.
I am working on the section where we have to launch mongod using a config file. I have saved my file inside the shared folder and then ssh’d into the VM. When I ls, there is no shared folder in the root directory or even in my data directory, was there something I missed during the initial setup of vagrant?
EDIT: I did try halting vagrant and restarting it, but to no avail.
