[pve-devel] KVM Templates on CephFS are only shown on one node - not all nodes in the cluster

Hi,

Sorry, I misspoke - it's not CephFS, but just normal Ceph RBD volumes.

But yes - these should be available to any clients connected to the Ceph
pool, right? AFAIK, there aren't any restrictions applied:

If I go to list the contents of the Ceph storage, I can see the templates
there on each node:

The templates are base-500 and base-100 - these are present on the Ceph
volume on each node.

However, if I expand the servers on left-hand side, I can *only* see the
KVM templates on the first node (where they were created) not the other
nodes.

Is there some way to get a template to appear for *all nodes in the
cluster?*

Thanks,
Victor
