Some days ago I wished to give the same answer... ...but then I changed my mind.

I couldn't convince myself that the odd number of voting disks is enough.

I concluded I don't know how the voting mechanism in RAC is truly working (and I couldn't find documentation on the topic).

Maybe it is the flu or I'm naturally dumb but what happens if every voting disk is owned by a different node or no node owns enough disks?

Being at home I have no chance to play with a test system so if someone can post the list of file descriptors involving every voting disk grouped by process (on any node)...
