[LU-19082] 'df' does not show actual usage when over quota

• Type: Bug

Description

Running 'df' on a directory with a hierarchical project quota where the project is over quota, then the filesystem usage is always reported at 100%, instead of the actual percentage used (over 100%).

$ lfs quota -a -p /fsname/test_quota/ -h
Filesystem /fsname/test_quota/, Disk prj quotas
  quota_id    used   quota   limit   grace   files   quota   limit   grace
         0  3.312T      0k      0k       -  402811       0       0       -
       111  2.245T*   900G      1T       -      16       0       0       -
$  df -h .
Filesystem            Size  Used Avail Use% Mounted on
mgsnode@o2ib:/fsname  900G  900G     0 100% /fsname

It should report the actual space usage and (hopefully) df will report a percentage used over 100% used.
