[Ocfs2-users] Problem installing CRS

[Martin Norland]

I'm trying to install 10.2.0.1 (and then patch up to 10.2.0.3).  The
first step, of course , is to install CRS - but I'm getting the
following error when trying to specify the OCR location:

"The location /u02/ocr, entered for the Oracle Cluster Registry (OCR) is
a directory.  Specify a shared raw partition or cluster file system file
that is visible by the same name on all the nodes in the cluster."

The intention is to have 3 small partitions for the {2} OCR and {3} CSS
mirror(s), but I can't seem to get Oracle to acknowledge they're
clustered.  The clustered filesystems work fine, and cluvfy recognizes
them as shared.

=========

It's worth noting that I was mounting these through powerpath, but
backed off to /dev/sd identifiers in an attempt to get Oracle to
recognize them (since cluvfy wasn't acknowledging /dev/emcpower's).  I'd
originally intended to mount these off /u0#/cd#/, but also backed down
in attempt to get Oracle to spot them.

Any thoughts or any glaring holes in my setup that this noob is missing?
I didn't find anything on metalink related to this error, other than
recommendations to use raw devices (recommendations for a different
configuration).

Thanks,
