guide: using NFS as a remote storage

[efiop]

I.e. mount it to some dir and specify it as a local dir repository for dvc.

I have generalized this as "Mounted DVC Storage", which includes not only NFS, but also SSHFS, Samba, or any other data storage that can be network-mounted on a local directory.

I have also built an interactive example that explains how to do it for SSHFS (since this is easier to set up for an interactive example): https://katacoda.com/dvc/courses/examples/mounted-storage

@efiop did you mean in https://dvc.org/doc/command-reference/remote/add though? Or somewhere else.

[efiop]

@jorgeorpinel I guess a note there would also be pretty nice as a way of using any storage that you can mount to your local fs.

OK. So while #784 greatly simplifies this issue, it won't completely solve it. I'm updating the PR's description to remove the link. Or if you prefer to also add the note Ruslan suggests Dashamir, please reestablish the link to close this issue automatically from your PR. 🙂

I read the comments in #784. Is there anything that should be done here?

It feels that we don't have a perfect place at the moment to put this note. I think there should be something about remotes in the User Guide in the first place. Starting from basic concepts, expanding into a proper section, where we can put a note in the introductory part about "Unsupported directly remotes" with a solutions like sshfs, mounted NFS, etc. For now, we can probably create a section and a note in the existing remote add, remote modify, remote index with the same meaning.

Added this to https://github.com/iterative/dvc.org/issues/2866.

QQ @dberenbaum: This has a low priority now but https://github.com/iterative/dvc.org/issues/4303 (part of this one) a high priority. 🤔 Does that mean you want to focus on the latter without addressing the former (this one) ?

[dberenbaum]

@jorgeorpinel In https://dvc.org/doc/user-guide/data-management/remote-storage#file-systems-local-remotes, you added:

You can also use system directories, mounted drives, network resources e.g. network-attached storage (NAS), and other external devices as storage.

Is that enough to close this one? Do we need anything else for this issue specifically?

[jorgeorpinel]

Maybe just add "mounted drives (e.g. NFS)" (link to https://nfs.sourceforge.net/ ?) unless the intention here was specifically about NFS for some reason, and not in general any mounted drives. Note that there are NFS-specific notes in the config options state.dir and index.dir.
