This is the way. 🤭

The second install should be easier since is done just after a test one.

Add a second node using the new drive, move all vm to the new node, decommission old node, rebuild the old node with the new drive.

You can get away with a disk clone but in my opinion a vm move is the proper way to go.

Adding a new node you start with a clean install, any quirk you have on the old hw will be finally washed away (or will bite you back and be properly documented), you have a quick way back should anything go sideways (the clone too provides a quick way back, but i like this way much more ^^), you get some hands on multi node experience that will be useful for ha setup.

Normal background noise. ssh is a well known protocol/port and scanning is automated.
