How to Manage Data

Get Permitted Storage

You should first have at least one permitted storage to manage data in OpenPAI. To view your permitted storage, first, go to your profile page:

view profile

Then all storages you have access to will be displayed:

storage config

If the display list is empty, please contact the cluster administrator.

Upload data

There are multiple types of storage. We will introduce how to upload data to NFS, AzureBlob, and AzureFile storage as examples.

Upload data to NFS

Upload data to NFS server on Ubuntu (16.04 or above)

For Ubuntu users. To upload data to an NFS storage, please run the following commands first to install NFS dependencies.

sudo apt-get update
sudo apt-get install --assume-yes nfs-common

Then you can mount NFS into your machine:

sudo mkdir -p MOUNT_PATH
sudo mount -t nfs4 NFS_SERVER:/NFS_PATH MOUNT_PATH

Copy your data to the mount point will upload your data to NFS.

The NFS_SERVER and NFS_PATH can be found in the Storage section on your profile page.

Upload data to NFS server in Windows

You could access NFS data by Windows File Explorer directly if:

  • The cluster administrator setup NFS by storage-manager. storage-manager will provide a samba server.
  • The cluster administrator configures a samba server along with the NFS server by himself.

To access it, use the file location \\NFS_SERVER_ADDRESS in Window File Explorer. It will prompt you to type in a username and a password:

  • If OpenPAI is in basic authentication mode (this mode means you use a basic username/password to log in to OpenPAI webportal), you can access NFS data through its configured username and password. Please note it is different from the one you use to log in to OpenPAI. If the administrator uses storage-manager, the default username/password for NFS is smbuser and smbpwd.

  • If OpenPAI is in AAD authentication mode, you can access NFS data through the user domain name and password.

If it doesn't work, please make sure the network discovery is on, or contact your administrator for help.

If you cannot use direct access, please try to mount NFS into Windows or using a Linux VM to upload data.

Upload data to Azure Blob or Azure File

For Azure Blob, you can get the storage account name and container name on the profile page.

For Azure File, you can get the storage account name and file share name on the profile page.

To upload data to Azure Blob or Azure File, please:

  1. Download and install Azure Storage Explorer.
  2. If you use AAD to login into the PAI portal, the administrator should already permit you to access storage. You can get the storage account name, container name, and file share name on the profile page. Please use them to access storage in Azure Storage Explorer. For more details, please refer to storage explore: add resource via azure ad.
  3. If you use basic authentication (username/password) to login into the PAI portal, please ask your administrator for the storage access key. Then you can add the storage by access key and storage account name. For more details, please refer to storage explore: use name and key.

Use Storage in Jobs

Use Data Section UI

You can select desired storage in the Data section on the job submission page:

storage submit

As shown in the picture, corresponding storage will be mounted to /mnt/confignfs folder.

Use Job Configuration File

You can also specify storage names in extras.storages section in the job configuration file:

    - name: confignfs
      mountPath: /data
    - name: azure-file-storage

There are two fields for each storage, name and mountPath. name refers to storage name while mountPath is the mount path inside job container. mountPath has default value /mnt/${name} and is optional.

Set it to an empty list (as follows) will mount default storage for the current user in the job.
