Perdeu todos os Voting Disks?

Calma, não há motivo para desespero. Na demonstração abaixo, eu tenho apenas um Voting Disk para o Oracle RAC, em um compartilhamento NFS. Ou seja, uma péssima idéia: lembre-se que se eu perder 50% + 1 dos meus Voting Disks, o Cluster fica indisponível.

Veja que ao apenas remove-lo do diretório, o Cluster não gera erro algum (talvez porque o Voting Disk estava em Lock pelos Nodes, via NFS ou SO, e não foi realmente removido). Só ao reiniciar o Cluster que ele sente a falta do Voting Disk.

Mas não há problema, veja que basta reiniciar um dos Nodes em modo Exclusivo, e adicionar um novo Voting Disk, que pode ser até com o mesmo nome do anterior.
