Issue

• I am unable to create Glance images in the OpenStack STAGE environment. Glance backend is configured as follows:

cat /etc/glance/glance-api.conf:
...
filesystem_store_datadir=/var/lib/glance/images/
...

• When there is a local file system mounted under "/var/lib/glance/images/" directory, then there are no problems with creating Glance images. However, when there is a remote NFS share mounted under "/var/lib/glance/images/" directory, then all created Glance images end in the "Killed" status and there is the following messaged displayed in the "/var/log/glance/registry.log" file:
