On the 2.6 kernel, I've heard that the Ext2/3fs can handle 16TB by 
increasing the block size (I'm not sure if that number is with 4K or 8K 
blocks). 

Is it possible to increase the FS capacity in GFS on 32bit systems in 
the same way (ie, by increasing the block size)?  If so, what is the 
maximum block size supported in GFS

Thanks!
