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

[Luis Freitas]

Tina,
 
   The raw devices are being deprecated on Linux. Since you are using fedora instead of a enterprise distro these changes are already done.
 
   You can use disk devices directly with the 11g clusterware. Also it probably would work with the main tree OCFS2, that doesnt has the datavolume option, since this implies that the clusterware writes on these devices using O_DIRECT, but AFAIK this not tested on the main OCFS2 and since the clusterware uses some heuristics to turn on these options it could not work with OCFS2.
 
   If you have metalink access check note 401132.1. Beware that this is broken on 10gR1 and probably the initial 10gR2 patchsets. I didnt found references of patches to include the O_DIRECT on the 10g version of the CRS so I am not sure when this was fixed.
 
Regards,
Luis

OK, another snag.  Fedora 9 does not support RAW devices, so I can't
configure the voting disk or OCR disk to be as such.  Any suggestions? I
think I'm "up a creek" here...

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.
