Permanent storage
The storage system is divided in three principal partitions, each one with different memory space and file limits. To avoid unexpected failures we recommend that you verify that you have enough space for your jobs before submitting them. Special care must be observed in the HOME quota. Inability to write to the home will cause many services and applications to crash.
If you are close to reach your quota and you need to increase the limits, you can ask for an Additional Storage Request.
Note
$HOME and $STORE directories are shared between FinisTerrae II and FinisTerrae III.

Filesystem Quotas
The filesystems have usage quotas that limit both the maximum allowed number of files and the total space used.
To see your current filesystem quotas and how close you are to reach the limits you can use the myquota
command.
