Hello,
I have 2* PVE nodes, both are running same version of proxmox
The node #1 already has 4* VMs in production.
I have and tested daily backups of each VMs.

I'd like to configure replication on the second node..

Both nodes are already in a cluster.
On node #2, I have created the zfs pool without checking the "Add Storage".

Now, if I go to:
-> DataCenter
-> Storage
-> Double-click: zfs-storage
-> Edit ZFS
-> add nodes #2 to the configuration
...

Is there any risk of data loss (vms) from node #1?

best regards,
 
Hi,
the steps sound fine to me. Please note that a two node cluster won't be operational when one of the nodes is down, because there is no quorum. Many people use a QDevice for external vote support for such setups. If you then use HA (but proper HA should really use >= 3 nodes) and there is a node failure, the VM will be recovered on the other node, which means that the data from after the last replication will be lost.
