You need something to break a tie.
If you had any even numbers of voting disk ( say 2 ) and a 2 node cluster ... what happens if one voting disk has a vote for node1 and the other for node 2?
Voting disks among other things can lead to a rac node getting evicted ( thrown out ) of a rac cluster. Received on Mon May 04 2009 - 14:41:30 CDT
