The total storage space of
/scratch is 30 TiB.
Each user has a scratch directory
The area is meant as a temporary scratch area. This area is not backed up.
There is no quota in the scratch area.
/scratch/ area enforces an automatic cleanup strategy, files in this
area will be deleted after 21 days.
If file system usage reaches 75%, files in
/scratch/ will be deleted even
before 21 days.
Each NIRD Data Storage project gets a project area either on NIRD TS
or on NIRD DL
/nird/datalake/NSxxxxK based on the project allocation,
NSxxxxK is the ID of the project.
The project area has a quota on disk space and the number of files. You will keep the current quota on the old system until it is end of life. You get the quota allocated by RFK for the 2022.2 allocation period on NIRD. NIRD TS(Resource: projects) and NIRD DL (Resource: datalake) will have separate quota based on the project allocation. You can see the quota and the current usage by running:
$ dusage -p NSxxxxK
