Nextcloud

We provide access to the Nextcloud instance running in our cluster and using our CephFS storage. It’s similar to other file sharing systems (Dropbox, Google Drive, etc.) and can be used to get data in the cluster, temporarily stage the results, share data and so on. If you’re planning to use it for large datasets, please contact us first with the usage plan.

Note that large files may take a long time to show up after the upload because the uploaded files are chunked and then reassembled. This is a similar constraint to our Ceph S3 storage.

Using Nextcloud from shell

To access your Nextcloud storage from shell (or Jupyter), you can use the rclone tool. It’s already installed in our Jupyterlab service. While the web interface is also possible to use, rclone with WebDAV may be more reliable for many or large files.

To get access, create new rclone config:

Terminal window
jovyan@jupyter:~$ rclone config
