You find solutions for problems with exceeded quota on the HOME file system.

Check the quota

Check the quota on HLRN with the command hlrnquota. Once your account is a member of a unix group, you find quota informations additionally for all groups. Each of your files belongs to your account or to one of your unix groups.

File and unix group

For each file on disk you can figure out to which unix group it is attached to.

Read unix group
blogin4> ls -la
-rw-------  1 myaccount myaccount 237271040 Jul  3  2020 somefile.txt
drwx------  1 myaccount  prj00012      4096 Jul  3  2020 somedirectory

You can modify the unix group of a file or a directory tree.

Modify unix group
blogin4> groups
myaccount prj00012
blogin4> chgrp prj00012 somefile.txt
blogin4> chgrp --recursive prj00012 somedirectory
blogin4> ls -la somefile.txt
-rw-------  1 myaccount prj00012 237271040 Jul  3  2020 somefile.txt

HOME quota exceeded

You have the following solutions if your HOME quota is exceeded.

  • remove files or move files from HOME to WORK (no backup) or to PERM
  • ask your consultant for a higher quota

The HOME file system (HOME=/home/${USER}) is intended to be used for the following data.

  • configuration files
  • source code and executables

You might experience an exceeded HOME quota due to unintended usage of the HOME file system, e.g.

  • large files
  • parallel input/output for your jobs

WORK quota exceeded

You have the following solutions if your WORK quota is exceeded.

  • remove files or move files from WORK to PERM
  • change unix group for files to "move" quota from your account to a unix group (e.g. prj00012)
  • ask your consultant for a higher quota

The WORK file system (WORK=/scratch/usr/${USER}) is intended to be used for the following data.

  • large files
  • parallel input/output for your jobs
