Nial thanx for the answer.
We are not expert in linux/unix environment and file systems. We followed this article to build a RAC: and we were going to believe that we should use ocfs2 file system and then must format the new file system.
Using RAW or ASM for the standalone will let us avoid (clustering) to create other file systems and copy original database. Bye
