Unfortunately - yes. You can use a tmpfs, if you have enough RAM on your host, to speedup a process.
You should have enough RAM to put there sql dump, and new db. So, approximately double and half of size of the actual database.
I have another new node running with same pubblic IP address, in this case having the first node stopped due dB recovery and taking so much time like days before the end of this fix, the first node will be suspended ?
Why?
All nodes are independent of each other. The filtering by IP is performed on the satellite.
You first node now could have a double increase of requests to store something
