If you see the error “storage ID ‘pool’ already defined” in Proxmox, it means that a storage with the same ID already exists on the system.
Each storage in Proxmox must have a unique ID, so you will need to choose a different ID for your storage or delete the existing storage with the same ID.
To fix this issue, you will need to choose a different ID for your storage. You can use the
pvesm list command to see a list of existing storage IDs. Choose an ID that is not already in use and specify it when creating your new storage.
For example, if you want to create a new ZFS storage with the ID “new storage”, you can use the following command:
pvesm create zfs new_storage
This will create a new ZFS storage with the ID “new_storage”. Make sure to use a unique ID for your storage to avoid this error.
To delete the existing storage, you can use the Proxmox web interface or the
pvesm command-line tool.
pvesm remove pool
Once the existing storage has been deleted, you should be able to create a new storage with the same ID. Make sure to carefully plan and test your configuration before implementing it in a production environment.
