Although official Oracle documentation indeed suggests that:
<http://oss.oracle.com/osswiki/OCFS2/NewFeaturesList>
"Extended Attributes
Required Kernel: Linux 2.6.28
Required Tools: Ocfs2 Tools 1.4.4 (not yet released)"

I can use EAs after creating an OCFS fs with xattr support:

# mount | grep ocfs
/dev/sdb on /mnt type ocfs2 (rw,_netdev,cluster_stack=pcmk)
# cd /mnt/
# setfattr -n user.test -v bla file
# getfattr file
# file: file
user.test
