An initial guess is you did not set up the project in xfs_quota using the
'project -s' xfs_quota command.

'project -c' output should look like this:

xfs_quota> project -c testproject  
Checking project testproject (path /mnt/test/testa)...
Checking project testproject (path /mnt/test/testb)...
Processed 2 (/etc/projects and cmdline) paths for project testproject with 
recursion depth infinite (-1).

But if you don't set up a project you might see something like this:

xfs_quota> project -c testproject
Checking project testproject (path /mnt/test/testa)...
/mnt/test/testa - project identifier is not set (inode=0, tree=33)
/mnt/test/testa - project inheritance flag is not set
/mnt/test/testa/file - project identifier is not set (inode=0, tree=33)
/mnt/test/testa/file - project inheritance flag is not set
Checking project testproject (path /mnt/test/testb)...
/mnt/test/testb - project identifier is not set (inode=0, tree=33)
/mnt/test/testb - project inheritance flag is not set
Processed 2 (/etc/projects and cmdline) paths for project testproject with 
recursion depth infinite (-1).

And you'd have similar symptoms.  You can also check which project the files
you created are in by using the xfs_io 'lsproj' command.  There is also a
'chproj' command if find that your existing files aren't in the project and
need to add them in.

Regards,
        Ben
