Storage naming question

I have a general question because I think I misunderstood something about Proxmox.
I have two nodes, and I have configured ZFS on both of them.
On node 0, my ZFS pool is called "pond", whereas on my node 1, the ZFS pool is called "tank".
I want the disk images of my VMs and CTs to reside on the ZFS pools.
I created a storage "images", but I can only assign either pond or tank to it, not both. This leads to the following problem: assume I migrate a VM from one PVE node to another, I get the error message that the target storage does not exist - obviously, because I can have the storage "images" only on one node.
Is it somehow possible to fix this problem, and how should I name my storage such that the migration of nodes works as intended?
 
Hi,
yes PVE expects that a storage has the same parameters on all nodes it is used for.

You could create a second storage, set the nodes restriction for both of them and use the targetstorage option for migration (not exposed in the GUI). But replication won't work like that.

The much better solution is to use the same name for the ZFS on both nodes.
