Just specify block devices for voting disk and ocr. CRS should open
the block device with the O_DIRECT flag.
OCFS2 has two code trees. The 1.2 tree is the "supported" tree
and build on 2.6.5 (SLES9) and 2.6.9 (EL4). It has some additional
code, like to support "datavolume" mount option.
The other code tree is the mainline kernel. That's where all the new
development happens. However that tree does not have some oracle
specific code, like the aforementioned datavolume mount option.
Most distros, like fc and ubuntu, ship the mainline version of OCFS2.

hi,
since in the current version of udev in fedora dont have the support
for standard i/o based raw and asm doesnt compiles for my kernel
(2.6.19.x), i have to use clustered file system for voting disk and ocr.
You notified me as mainline version, i am using.
I dont get it?
does the subversion from development holds support for it?Any other
ways of using ocfs2?
thanks for the response

current version of ocfs2

If you want to use the mainline version of ocfs2, use a raw partition
for the voting disk and ocr.
For the db, specify filesystemio_options=directio in init.ora.

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:
[EMAIL PROTECTED] ~]# 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.
