BlueData MLOPS - PermissionError: [Errno 13] Permission denied

I've created a MLOPS project on BlueData 4.0 and mounted the Project Repo (NFS) folder. I created the NFS service on Centos 7x as below:

  sudo yum -y install nfs-utils
  sudo mkdir /nfsroot
  echo '/nfsroot *(rw,no_root_squash,no_subtree_check)' | sudo tee /etc/exports
  sudo exportfs -r
  sudo systemctl enable nfs-server.service
  sudo systemctl start nfs-server.service

I'm now trying to access a data set stored in the NFS Project Repo, but I'm receiving the following error:

PermissionError: [Errno 13] Permission denied: '/bd-fs-mnt/path/data.csv'

Any idea how I can fix this?

Solution

  • It appears the project repo is created with root as owner and no write permissions on group level.

    To fix, you need to:

    • create a notebook cluster
    • open a Jupyter Terminal
    • sudo chmod -R 777 /bd-fs-mnt/nfsrepo (this only works if you create that cluster as tenant admin, as user you don't have sudo permission)
