most of the stuff I have seen on this says yes you can do it, i have seen the odd metalink doc that says no however, something about oracle needing to cross mount the arc log in the event that recovery is needed.

I myself just have datafiles, redo and control files on ocfs, I got the admin to allocate a portion of the san for ntfs.

I create arch logs on each local file system with copies of them
on the ntfs portion of the san. The ntfs portion is *attached* to a specific node and can be accessed by other nodes to NT file sharing.
