Unable to activate storage when creating VM

I just wiped and reinstalled Proxmox on four nodes and created a cluster. Three nodes are identical hardware with identical installs. The fourth node (Powerhouse) is higher-spec'd hardware, and required a lot more setup than the others to get a Realtek network driver working. Powerhouse is running kernel 6.14 while the other nodes are running 6.8. I have them setup as a cluster, and in the cluster I have mounted a share from my NAS (RadNAS). I have backup VM disks already on the share that I was hoping to restore, by creating new VMs. When I create a new VM on Powerhouse, I get an error "unable to create VM, unable to activate storage RadNAS."

I can access the share on RadNAS from the CLI, but it says it can't activate it when creating a VM. What could be causing this? Is it an issue that the nodes aren't on the same kernel?
 
Hi,

Did you have a chance to check the mount to ensure that everything is OK?
It can be some permissions issues or incorrect mount options.
Why you using direct mount instead of add the the share as a storage to PVE?
