From this article:http://dbarohit.blogspot.com/2012/12/why-oracle-recommends-voting-disks-in_25.html, it said 「A node must be able to strictly access more than half of the voting disks at any time」.
My question is Why it must be able to strictly access more than half of the voting disks at any time? In my RAC environment, if it exists only one voting disk or two voting disks, then what will be happen?
If a node cannot see at least half of the voting disks, it will never be able to win in a split brain scenario (which is resolved by nodes trying to reserve voting disks). If you only have a single voting disk and it fails - your cluster goes bye-bye. If you have an even number, what happens if 2 nodes each acquire exactly half - who wins?
