[Ocfs2-users] data volume option, is it present in current version of ocfs2

[nirmal tom]

hi,
i am trying to install oracle rac on fedora core 6 through iscsi.

when i try to mount,
mount.ocfs2: Invalid argument while mounting /dev/mapper/rac-crs on 
/mnt/crs. Check 'dmesg' for more information on this error.

error log in dmesg,
ocfs2: Unmounting device (253,11) on (node 255)
(27354,0):ocfs2_parse_options:753 ERROR: Unrecognized mount option 
"datavolume" or missing value

version of ocfs2:
[root at server ~]# rpm -qa | grep ocfs
ocfs2console-1.2.2-1
ocfs2-tools-devel-1.2.2-1
ocfs2-2.6.9-42.EL-1.2.4-2
ocfs2-tools-1.2.2-1

i googled and found this datavolume option was taken from 1.2 but also it is 
quite needed for voting disk.I saw the dates of threads discussing this 
problem and it is almost 7 to 8 months back.

how to make it work? is any new version available now? or how to fix it?

thanks for any response.

regards,
