Check your quota

Check your disk quota limits on HLRN with using the command hlrnquota. Once If your account user ID is a member of a UNIX groupone or more project groups, you find quota informations additionally for all will also get quota information for these project groups.

Quota on HOME and WORK

For each file and directory stored file on the file systems HOME and WORK the UNIX group of this file controls the attribution to the quota to this UNIX group. For quota, the directory of a file (/scratch/usr/${USER} or /scratch/projects/<projectID>) does not matterfile systems, its group ownership affects the disk quotas of that particular group – no matter where the file or directory itself is located.

Each user account ID is a member in of one or more UNIX groups. You can check your membership in UNIX groups Group memberships can be checked with the groups command groups.

blogin4:~ $ groups myaccount
myaccount prj00012

Once When, for example, you decide to set change the UNIX group ownership of a file to prj00012 for a file, the used quota for the UNIX group prj00012 includes this file size, the size of this file will affect the disk quota of group prj00012.

blogin4:~ $ chgrp prj00012 somefile.txt
blogin4:~ blogin4>$ ls -l somefile.txt
-rw-------  1 myaccount prj00012 237271040 Jul  3  2020 somefile.txt

blogin4:~ $ chgrp --recursive prj00012 somedirectory
blogin4>blogin4:~ $ ls -ld somedirectory
