What Is DICE Project?

DICE (Developing Innovation and Creativity in Education) is an international project co-funded by the Erasmus+ Programme of the European Union.

Its main goals are related to fostering innovation and creativity in education.

This project attempts to be a leading initiative that supports educational community to make progress in the field of innovation and creativity through effective, authentic, practical, sustainable actions. This project has been funded with support from the European Commission. For more information, see [http://www.diceproject.eu/][b].

IT4Innovations participates in DICE. DICE uses the iRods software

The integrated Rule-Oriented Data System (iRODS) is an open source data management software used by research organizations and government agencies worldwide. iRODS is released as a production-level distribution aimed at deployment in mission critical environments. It virtualizes data storage resources, so users can take control of their data, regardless of where and on what device the data is stored. As data volumes grow and data services become more complex, iRODS is serving an increasingly important role in data management, see [https://irods.org/][c].

How to Put Your Data to Our Server

Prerequisities:

We have to be sure about your identity, this will be done throught this steps:

  • sign in with your organisation B2ACCESS , pages requests valid personal certificate (e.g from GEANT) . Account with "Low" level of assurance, will not have access to IT4I zone

  • confirm your certificate in browser

  • confirm your certificate in OS (Windows)

  • sign to EUDAT/B2ACCESS

  • after successfull login to B2Access, please sign in to our AAI throught your B2Access account. You have to set new password - it is for iRods access.

  • contact our support@it4i.cz by mail, we will create your account at our iRODS server.

  • fill this request for EUDAT, please specify requested capacity.

Access to iRods collection from cluster Karolina

  • access to cluster is must (it4i account)
  • iRODS clients are provided as a module on our Karolina cluster ( Barbora is in progress )
  • module irodsfs loads config file for irodsfs nad for icommands too
  • PAM passwords is password, you set in aai.it4i.cz

How to mount your collection

ssh some_user@karolina.it4i.cz
ml irodsfs
  • now you can choose between Fuse client or iCommands

Fuse

ssh some_user@karolina.it4i.cz
[some_use@login4.karolina ~]$ ml irodsfs

irodsfs configuration file has been created at /home/dvo0012/.irods/config.yml
iRODS environment file has been created at /home/dvo0012/.irods/irods_environment.json

to start irodsfs, run:          irodsfs -config ~/.irods/config.yml ~/IRODS
to start iCommands, run:        iinit

For more information, see https://docs.it4i.cz/dice/

To mount your iRODS collection to ~/IRODS, run

[some_user@login4.karolina ~]$ irodsfs -config ~/.irods/config.yml ~/IRODS
time="2022-08-04 08:54:13.222836" level=info msg="Logging to /tmp/irodsfs_cblmq5ab1lsaj31vrv20.log" function=processArguments package=main

To unmount it, run

fusermount -u ~/IRODS

{==

you can work with fuse as an ordinary directory ( ls, cd, cp, mv etc )

==} iCommands

ssh some_user@karolina.it4i.cz
[some_use@login4.karolina ~]$ ml irodsfs
irodsfs configuration file has been created at /home/dvo0012/.irods/config.yml.
      to start irods fs run: irodsfs -config ~/.irods/config.yml ~/IRODS

iCommands environment file has been created at /home/$USER/.irods/irods_environment.json.
      to start iCommands run: iinit

[some_user@login4.karolina ~]$ iinit
Enter your current PAM password:
[some_use@login4.karolina ~]$ ils
/IT4I/home/some_user:
  test.1
  test.2
  test.3
  test.4
  • upload iput , download iget
  • for more help, type ihelp

Access to iRods collection from other resource

  • we suppose, you will upload your data from your local pc/vm
  • password from AAI

You Need a Client to Connect to iRods Server

  • There are many iRods clients, but we recommend theese:
  • Cyberduck - for windows / mac, GUI .
  • Fuse (irodsfs lite) - for linux, cli
  • iCommands - for linux, cli .
  • for access set PAM passwords at AAI

Cyberduck

Fuse

  • work with your irods collection like ordinary directory
  • this is linux client only, basic knowledge of commandline is neccessary
cd ~
wget https://docs.it4i.cz/irods1.it4i.cz.crt [k]
wget https://github.com/cyverse/irodsfs/releases/download/v0.7.6/irodsfs_amd64_linux_v0.7.6.tar
tar -xvf ~/irodsfs_amd64_linux_v0.7.6.tar
mkdir ~/IRODS ~/.irods 
cd ~/.irods && wget https://docs.it4i.cz/config.yml
  • edit ~/.irods/config.yml with apropriate username

***How to start - mount your collection:***

```console
[some_user@local_pc ~]$ ./irodsfs -config ~/.irods/config.yml ~/IRODS

sudo yum install epel-release -y
sudo yum install python-psutil python-jsonschema
sudo yum install irods-icommands
cd ~ && wget https://docs.it4i.cz/irods1.it4i.cz.crt [k]
mkdir ~/.irods/ && cd "$_" && wget https://docs.it4i.cz/irods_environment.json
  • edit irods_user_name in ~/.irods/irods_environment.json 
[some_user@local_pc ~]$ pwd

[some_user@local_pc ~]$  ls -la
total 16
drwx------. 2 some_user some_user 136 Sep 29 08:53 .

-rw-r--r--. 1 some_user some_user 253 Sep 29 08:14 irods_environment.json

How to Start:

step 1:

[some_user@local_pc ~]$ iinit
Enter your current PAM password:

[some_user@local_pc ~]$ ils

  file.jpg

how to put your data to IRODS
