Swestore-iRODS

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

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.

• Please check full and updated documentation at iRODS official Documentation.
• The command line client may be downloaded from iRODS Download page.
  • Please check "Binary Distributions" and instructions for configuring your package manager to include irods APT, YUM or ZYPPER repository at Repository of iRODS packages .
  • You can check here an example of iRODS iCommands installation on CentOS 7 from repository.

• 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>.:
