I upgraded our GI from to, but it's not a standalone ASM, so it's not exactly the same setup as you mention. In any case I wrote down how it was done, so it might help others.

I've been running since February and I didn't hit the bug you're talking about.

A quick fix for your problem is to run a find(1) from your GI owner user's crontab which removes the core files. It won't fix the problem, but at least it will save you from a file system full problem. Of course the real fix is to have Oracle issue a patch for this, but it might take some time. Meanwhile, something like this could help:

find $GRID_HOME/log/`hostname`/diskmon -type f -iname "*core*" -exec rm {} \;

Just make sure you don't have other files that match the pattern "*core*" in that directory and below that you want to keep.

HTH, David
