I need to relocate a physical cluster from one data center to a new one, here some information about this scenario:
Having said that let's get to the point, there's no backup and there's no way to guarantee that the nodes will continue to work well after being turned off and moved.
There are nodes that have not been turned off for more than 500 days, I have no idea how their disks will support the moving.
I'm saying this because the hypothetical loss of several nodes from different racks can cause data loss. Again, no backup.
I need to ensure the cluster is up and running after the move without data loss.
I've been thinking in two different approaches to mitigate this situation, kinda disaster recovery plan:
I was wondering if maybe someone could help me with this.
Any suggestion is welcome.
