Your kernel is too old to support project quotas showing up properly
in df output.
A current kernel shows:
$ sudo xfs_quota -x -c 'project -s -p /mnt/scratch/foo 42' /mnt/scratch
Setting up project 42 (path /mnt/scratch/foo)...
Processed 1 (/etc/projects and cmdline) paths for project 42 with recursion depth infinite (-1).
$ sudo xfs_quota -x -c 'limit -p bhard=1g 42' /mnt/scratch
$ sudo dd if=/dev/zero of=/mnt/scratch/foo/bar bs=1024k count=100
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 0.133275 s, 787 MB/s
$ sync
$ $ df -h /mnt/scratch /mnt/scratch/foo
Filesystem Size Used Avail Use% Mounted on
/dev/vdb 11G 133M 11G 2% /mnt/scratch
/dev/vdb 1.0G 100M 924M 10% /mnt/scratch
Which is exactly what you are asking for. Solution: upgrade.
Cheers,
Dave.
