To specify file Project ID it is necessary to enable quota feature. 

According to the Lustre manual.

The project quota feature is disabled by default, and tune2fs needs to be run to enable every target manually."

To turn on user, group, and project quotas for block only on file system testfs1, on the MGS run:

mgs# lctl conf_param testfs1.quota.ost=ugp
