Does GFS somehow get around the 1TB block device issue? Just how large can a single exported filesystem be with GFS?



On Linux 2.4-based kernels, the limit is 1TB. On 2.6-based kernels, the
limit is 8TB on 32-bit systems and some really large number (at least
exabytes) on 64-bit systems.


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!
