yes, that patch has been merged into ocfs2-1.4 and should be ready for
the next release. Also as Joel said, "If you have the appropriate
support, you should call support and file that way."
Here is the workaround from the mail list, and I don't know whether it
is suitable in your case.
I would guess that you are upgrading from ocfs2-1.2 to ocfs2-1.4. If
that is the case please make sure which file cause this bug. Use
debugfs.ocfs2 -R "findpath <23693699>" /dev/sdh1 to see what the file is.
If that file isn't a datafile(I think it shouldn't be since the file is
only 5120 bytes) and your volume is used for other files(e.g Oracle
Home), then please remove "datavolume" from the mount option and instead
set the init.ora parameter filesystemio_options=directio (or is it
odirect). This should limit Oracle to use the odirect flag for the files
it should. datavolume is legacy, please refer to the OCFS2 1.4
Users Guide for further information about the datavolume option.
Wish it help.
Regards,
Tao
