[PVE-User] ZFS Replication on different storage

Hello Mark. 
I can't rename the zpool because is the primary pool (rpool). 

So i have: 

Node A: 
rpool/data (source) 

Node B: 
rpool/data (small partition) 
pool2 (my desired destination) 

I can rename rpool/data as rpool/data_ori, but i can't rename pool2 as rpool/data because is a different pool
