These tunables are normally for GFS internal development purpose and 
they come and go easily. If you take Red Hat GLS performance tuning 
class (https://www.redhat.com/training/), I think they have a section to 
describe that.

There was an early draft document that Dave Teigland helped me to write 
up in my people's page. You can take a look 
(http://people.redhat.com/wcheng/Patches/GFS/gfs_tune.txt) but I don't 
think it is very useful unless you know enough GFS internals.
