To run glance on multiple nodes you need shared storage like Ceph/NFS etc. Otherwise you won't be able to replicate images between all glance nodes. only if you dont use the glance multi store feature. you can have independet glance deployment with the file store without shared filesystem and automtic replciation in that case you can import image to speicic stores via the glance api.

and you can copy data between them using the image copy import scheme. to do this in kolla you will proably need to do the glance configurtion per host vai the config overriede mechanium but kolla shoudl provide the flexablity to configure that if you want too.

In the past I have deployed glusterfs running on all 3 nodes and mounts that filesystem into a glance docker container for shared filesystem.

I have made a deployment of openstack on multiple centos stream 8 nodes, and used files as a backend for glance service, but according to the documentation, when using file as a glance backend, It can only be deployed on a single node, what can I do to deploy it on multiple servers at once. Thank you.
