Image templates on CephFS shared storage only appear on one node?

Hi,

I have a 3-node Proxmox and Ceph cluster.

I am using Ceph RADOS for VM storage, and also CephFS to store some image templates.

I can see the image templates under the first server - however, they are not seen under servers 3 and 4:

I would have thought since CephFS is shared storage across the three servers, they'd appear on server's 2 and 3 as well.

Is there any way to get the image templates created on server 1 to also appear on servers 2 and 3?

Thanks,
Victor

No. But when you clone it, then you can specify the target node for the clone.
 
Ah got it - but say we lose one node 1 - then we no longer have access to the image templates (even though they're stored in CephFS, which would still be available across the other 2 nodes).

And if we make copies of those image templates on each machine - then it'd use up 3x the amount of storage on CephFS (I assume it doesn't do de-duplication).

Do you think it makes sense to make image templates on shared storage somehow visible in the menu on different nodes?
 
A template created of an VM/CT is stored as RBD image on Ceph, not on CephFS. But in any case, the config file of the template is in /etc/pve/nodes/<node name>/<qemu-server or lxc>/. You can either copy them by hand or let HA move them (state stopped).
