Someone from xCAT can hopefully confirm, but from what I have found, there is only 1 localdisk. You can make multiple partitions, but it will only use one. I too needed this functionality you are looking for, and gave up, instead writing a custom postscript to mount the other partitions. (not the best option, but what I had to do to get it working)

I’ve sort of gotten it to work, except that both filesystems seem to mount on the same partition. Anyone ever seen this, or have any ideas of what I’m missing? Also, what’s up with the “rw” filesystem mounted on /.sllocal/log?
