Description

Adding the dependency between this and https://bugzilla.redhat.com/1741730 Verified on:
openstack-cinder-12.0.10-19.el7ost.noarch
python2-glance-store-0.23.1-0.20190916165252.cc7ecc1.el7ost.noarch
On a system with OSP13, Glance uses Cinder as it's backend, this was setup for a previous bz.
Cinder uses Netapp NFS as it's backend.
Image_volume_cache is enabled on Cinder.conf
Simultaneously created 10 volumes from same image:
#for i in {1..10}; do cinder create 1 --image cirros ; done
Resulting 10 volumes all in available state as expected:
(overcloud) [stack@undercloud-0 ~]$ cinder list

Delete all volumes
I had now changed Glance to file store instead of Cinder as it's backend.
And retested again, create 10 cinder volumes from a new uploaded image
for i in {1..10}; do cinder create 1 --image cirros3 ; done
This too worked as expected:
(overcloud) [stack@undercloud-0 ~]$ cinder list

Confirming that image cache on NFS backend now works.
