Swestore iRODS

Swestore iRODS is distributed across two SNIC centres NSC and PDC. Data is stored in two copies with each copy at a different SNIC centre. This enables the system to cope with a multitude of issues ranging from a simple crash of a storage element to losing an entire site while still providing access to the stored data.

Using Swestore iRODS

Basic information

For basic information on how to apply for storage or how to become a member of an existing project, please check the main Swestore page.

Download and upload data

From the command line

There are several command line tools capable of using the protocols provided by Swestore iRODS. For interactive usage on SNIC clusters we recommend using the iCommands which should be installed on all SNIC resources. There are too many commands to document fully here.

  • Configuration of the icommands requires a file called irods_environment.json to be placed in a subdirectory .irods/ of your home directory (e.g. ~/.irods/irods_environment.json).

You must edit this with a text editor (not MS word, but notepad for Windows, textEdit for Mac or any Unix editor) and put your SNIC username in the place for <YOUR_SNIC_USER_NAME>.: 

{
  "irods_host": "irods-login.swestore.se",
  "irods_port": 2432,
  "irods_default_resource": "pdc-gpfs",
  "irods_home": "/snic.se/home/<YOUR_SNIC_USER_NAME>",
  "irods_cwd": "/snic.se/home/<YOUR_SNIC_USER_NAME>",
  "irods_user_name": "<YOUR_SNIC_USER_NAME>",
  "irods_zone_name": "snic.se",
  "irods_client_server_negotiation": "request_server_negotiation",
  "irods_client_server_policy": "CS_NEG_REFUSE",
  "irods_encryption_key_size": 32,
  "irods_encryption_salt_size": 8,
  "irods_encryption_num_hash_rounds": 16,
  "irods_encryption_algorithm": "AES-256-CBC",

From GUI client

Graphical User Interface (GUI) clients are known to work on some operating systems.

Access using WebDAV (map a network drive)

WebDAV endpoint for Windows 10, Linux and OS X is https://snic-irods-webdav.pdc.kth.se:8443/snic.se/

Mac OS X
Accessing Swestore-iRODS via WebDAV on Mac OS X
WebDAV is a method for remotely managing files over the internet. With WebDAV, you can access files stored in Swestore iRODS project by using the same interface as you do with your local files.

Once you connect via WebDAV, and you authenticate, you can view and manage the folders and files stored in your project area. You can perform same actions – drag and drop, rename, delete – that you would on files and folders stored on your own computer.

This is OS standard WebDAV connection · "Connect to server" function in Finder :

To access Swestore iRODS via WebDAV you'll need to authenticate with your username and password. 1.Click the 'Finder' icon

3.In the 'Connect to Server' dialog box, enter the URL to Swestore iRODS WebDAV endpoint, in the 'Server Address' field.

4.Click Connect.

Once the connection is made, you are prompted for your WebDAV username/password.

Once you’ve connected, the WebDAV directory is mounted in your 'Finder' and on your desktop.

You can now start adding, editing, deleting files in this directory from the comfort of your computer.

This is an example how to mount with iRODS resource via "mount_webdav" command in your terminal

If you prefer to access your Swestore iRODS files via command line, you can mount the WebDAV-enabled server directory via mount_webdav command

How to map the iRODS server to a Windows computer

1. You should have received an email telling you about your Swestore iRODS username 2. We’ll use "s_user" for example 3. We'll assume that you have set your password at SNIC SUPR for the Swestore iRODS account 4. Open “File Explorer” 5. Right-click “Network” 6. Click “Map network drive” 7. Click the hyperlinked "Connect to a Web site that you can use to store your documents and pictures." 8. Click "Next" two times 9. On "Specify the location of your website" enter https://snic-irods-webdav.pdc.kth.se:8443 10. Enter username and password, e.g. s_user and password 11. You should now see the folder mapped to File Explorer!
