[Ocfs2-users] Problems building ocfs2 rpm on Fedora 9

[Tina Soles]

Sunil,

I am setting up an Oracle RAC using these instructions
http://www.oracle.com/technology/pub/articles/hunter_rac10gr2_2.html#16

which states the following:

"Note: You are using the datavolume option to mount the new filesystem
here. Oracle database users must mount any volume that will contain the
Voting Disk file, Cluster Registry (OCR), Data files, Redo logs, Archive
logs, and Control files with the datavolume mount option so as to ensure
that the Oracle processes open the files with the o_direct flag. The
nointr option ensures that the I/O's are not interrupted by signals."

It is my understanding that the Voting Disk and OCR files must reside on
shared storage. I'm using a firewire drive for my shared storage. Is
there anywhere else I can place the voting disk and OCR files other than
my firewire drive? It is the only "shared storage" device that I have
setup.

Sorry about the confusion. Any help you can give me would be most
appreciated.

Thanks.

datavolume mount option is only on ocfs2 for enterprise kernels.

For most part, you shouldn't require it for using it as a datastore.
Instead set init.ora param filesystemio_options to directio (or is it
odirect).

The only bit that won't work here is using ocfs2 for the voting disk and
ocr... as datavolume is necessary to force enable odirect.
But you can always use raw for that.
