Description

Reproducer:
1) Disable creation of new objects on OST0002
pdsh g mds 'lctl set_param osp.l300test-OST0002-osc*.max_create_count=0'
2) Create files from a Lustre client and monitor with 'lfs df -i'. The number of used inodes increase on all the OSTs except OST0002.
3) Enable creation of new objects on OST0002
pdsh g mds 'lctl set_param osp.l300test-OST0002-osc*.max_create_count=1000'
4) Create files from a Lustre client and monitor with 'lfs df -i'. The number of used inodes should increase on all the OSTs, but does not increase for OST0002.
