i have the same problem here on EL3:
# uname -r
2.4.21-27.0.2.ELhugemem
# cat /etc/redhat-release
Red Hat Enterprise Linux ES release 3 (Taroon Update 4)
# rpm -q --qf '%{VERSION}-%{RELEASE}\n' coreutils
4.5.3-38

if i explicitely specify the blocksize

cp --o_direct=1048576 file_on_ocfs dir_on_ext3

it works. otherwise i get 'permission denied'.

database is 9.2.0.6 RAC.

Best,
