xfs directory quota doesn't work

[Simon Xia]

I do create two subdirectory for project

and the error maybe caused by this step:
xfs_quota -x -c 'project –c task1' /home/xiameng.xm/xfs_dir

–c - no such project in /etc/projects
Checking project task1 (path /home/xiameng.xm/xfs_dir/task1)...
/home/xiameng.xm/xfs_dir/task1 - project identifier is not set (inode=0,
tree=11)
/home/xiameng.xm/xfs_dir/task1 - project inheritance flag is not set
Processed 1 /etc/projects paths for project task1

I'm a little confused about the output message, cause everything is ok in
config file
