Purpose
This page presents ways to use storage5k for the storage reservation in Grid'5000.
Overview
Each user has a default storage space (/home) exported via NFS. For larger storage needs, a user can book another storage space for a determined period. storage5k allows users to book resources with OAR types of "storage".
Usage
First check the chunk disk size of the oar storage resources
malachheb@fsophia:~$ storage5k -a chunk_size Chunk size: 10737418240 (10 GB)
In this example the chunk size is 10GB, so for a reservation of 100 GB, you should ask for 10 chunks.
