has been increasing more than expected.

Therefore, the standard disk charge for the /home area

– Details:

    – The default quota value for the /home area of System B (ohtaka) will be

      reduced from 600GB to 300GB.

    – If you are using more than 300GB in /home,
      you may not be able to create new files and log in after the above reduction
      is implemented. Please delete files or expand the storage space
