Understanding the /etc/quotas file

How disk space owned by default users is counted

Disk space used by the default UNIX user

For a Windows name that does not map to a specific UNIX name, Data ONTAP uses the default UNIX name defined by the wafl.default_unix_user option when calculating disk space. Files owned by the Windows user without a specific UNIX name are counted against the default UNIX user name if either of the following conditions applies:

The files are in qtrees with UNIX security style.
The files do not have ACLs in qtrees with mixed security style.

Disk space used by the default Windows user

For a UNIX name that does not map to a specific Windows name, Data ONTAP uses the default Windows name defined by the wafl.default_nt_user option when calculating disk space. Files owned by the UNIX user without a specific Windows name are counted against the default Windows user name if the files have ACLs in qtrees with NTFS security style or mixed security style.
