The reason for the incorrect storage quota is inappropriate group ownership of directories/files. This can be checked by using ll or ls -l command and look and the column 4. The appropriate group ownership should be project ID.
For example, at line 4, the column 4 is hpcuser1 instead of lt200199. This makes storage quota of Folder2 (and all files in it) count toward user home.

drwxr-sr-x 4 hpcuser1 lt200199 4096 Jan 3 09:13 Folder4To change the group owner, use the following command.
chgrp -R lt2000xxx [yourfolder]The -R means recursive. With this option, chgrp will change the group ownership of a specified folder and all files/directories in it.
