OCM tutorial seems incomplete
The step that is supposed to demonstrate Accessing the share seems to be incomplete. It ends with Accessing the list of shares and the tutorial does not show how Marie can get access to the "Example file" text that Einstein uploaded.
The sending side does have ocdav enabled and there is a dataprovider service which I guess must be the "Data server" to which the file gets uploaded.
Hm

Please use `exit` or `Ctrl-D` to exit this program.

Maybe the tutorial is not even working with the latest revad versions, or maybe this error is due to something that's specific to the ocm-test-suite image and config. I'll try running it with the exact config from examples/ocmd
docker run -d --network=testnet --name=ocmd-server-1.docker -e HOST=ocmd-server-1 -v /root/michiel-dev/reva:/reva revad sleep 300000
docker exec -it ocmd-server-1.docker /bin/bash
$ cd /reva
$ export PATH=$PATH:/usr/local/go/bin
$ go mod vendor
$ make deps
$ make build-revad
$ make build-reva
$ cd /etc/revad
$ /reva/cmd/revad/revad -c ocmd-server-1.toml
docker exec -it ocmd-server-1.docker /reva/cmd/reva/reva -insecure -host=localhost:19000
And
docker run -d --network=testnet --name=ocmd-server-2.docker -e HOST=ocmd-server-2 -v /root/michiel-dev/reva:/reva revad
docker exec -it ocmd-server-2.docker /reva/cmd/reva/reva -insecure -host=localhost:17000
Working on this in https://github.com/cs3org/ocm-test-suite/tree/revad-edge-testing since I want to use the exact filenames as the tutorial and users/providers.demo.json have been edited in the main branch of the ocm-test-suite.
Note: The upload should be done to some path under /home/ and you need to
mkdir -p /var/tmp/reva/data/einstein/home
on the revad server first.
In the tutorial it says to mkdir /home/my-folder first, will try if that also works.
No, that step fails if /var/tmp/reva/data/einstein/home doesn't exist:
>> mkdir /home/my-folder

Testing this how with Nextcloud->Reva->Reva->Nextcloud configuration.

Debugging this more in https://github.com/pondersource/sciencemesh-php/issues/102 Once that is working we can also show it in the ocmd tutorial.
