Ocfs2 users - Jul 2008 - ocfs2 datavolume option and oracle

From the User's Guide:
> Oracle database users must mount the volumes containing the Voting Disk
file (CRS), Cluster
> Registry (OCR), Data files, Redo logs, Archive logs and Control files with
the
> datavolume,nointr mount options. 
However when this is tried, I get the following:
> ocfs2_parse_options:822 ERROR: Unrecognized mount option
"datavolume" or missing value
Searching the archives I found this post: 
http://www.mail-archive.com/ocfs2-users at oss.oracle.com/msg00201.html

Which seems to indicate that an older version of ocfs2 will be needed to 
host an Oracle installation.
> Long story short... use ocfs2 1.2 for running the oracle db.
However, I also saw this post: 
http://www.mail-archive.com/ocfs2-users at oss.oracle.com/msg02462.html

Which seems to indicate that a newer kernel (and thereby newer ocfs2) is 
needed to correct a memory leak.

So, I'm a little confused as to which ocfs2 version should be used and 
whether or not that means an older kernel (and potentially a memory 
leak) will be required.

In mainline, the issue was addressed in 2.6.21.

In enterprise kernels, the issue was addressed in 1.2.4-2.

If you are on (RH)EL4 or (RH)EL5, install 1.2.9-1.
If you are on SLES9 SP4 or SLES10 SP1, upgrade to the
latest kernel.

Thought that was what you meant, just wanted to make sure.

Thanks.

Jamin,

?? If you are using 10g you can create two 170Mb partitions for the OCR and
three 20Mb partitions for the voting disk, and you can leave the rest on a
single partition for the OCFS2 filesystem.

?? I never installed 11g RAC, but the manual says that each partition must be
280Mb or larger, so you will need at least two 280Mb partitions for one OCR and
one voting disk, preferrably five, for two OCR copies and three voting disks.

Regards,
Luis

Raw means specifying the block device directly. So make two
partitions, say, sdd1 and sdd2, and feed that (/dev/sdd1, etc)
to the tool that creates the voting disk and ocr.
