We are planing to enlarge our cluster with 16 nodes in the end.
the first 16 nodes are 4 years old, but still healthy and good enough!
But as you can imagine, 4 years ago, we added 4TB Disk space in each node.
now, we can do the same - 4TB per node - but from my point of view, this is not the way to go. We need current hardware.
I know from several postings, different disk sizes are not the way to go!
What is a good way?
Or i can build the new nodes with, let's say 8TB and create partitions with only 4TB. As long as the Old nodes are fine, we can add on this nodes 8TB as well and increasing the storage server by server.
Thank you very much for your input!
