-When using rsync to transfer to /project if you encounter the message <code>Disk quota exceeded</code> ensure you have not included the <code>p</code> option, either directly or indirectly with the <code>a</code> option as this can cause the group ID of the file to be incorrectly set. The group ID is used to apply a file's size towards a project quota.
+Some users have encountered trouble when using <code>rsync</code> to transfer directories into <code>/project</code>. The <code>-p</code> or <code>--perms</code> flag may cause the group ownership of files to be incorrectly set. Since quotas in <code>/project</code> are enforced based on group ownership this in turn may lead to <code>Disk quota exceeded</code>. The frequently-used <code>-a</code> or <code>--archive</code> flag implies <code>--perms</code>. Best advice is to use Globus or scp instead of rsync, but if you choose to use rsync, do not use <code>-p</code>.
