I am using the current kernel.org kernel with gfs2 ( 

What about documentation? for example is there any doc describing 
gfs2_tool tuning option?

Hi Mahmoud,

The latest mkfs.gfs2 in cvs has the -b option again, but
I'm not sure which packages that change made it in to.
I might be suggest a package if you tell me what platform,
otherwise you can build it from the source.
We temporarily disabled it while we were working on
alternate block sizes. 

If you're going to use alternate block sizes, you should 
make sure the gfs2 kernel module you're using will support
it properly.  Are you compiling the gfs2 kernel code from
the nmw git tree?  Or are you just using an installed package?
