What is the cluster size for linux?

| I think it's 32 but I just wanted to double check. Is there are there any
RPM's that can make the system go from 16, to 32, then to 64? I am guessing
that is where the kernel needs to be configured right?
Thanks,

I am not sure what you are referring to. Clusters are the disk
allocation unit in the Windows FAT/FAT32 partitions. The minimum unit
of disk allocation in Linux that would be the closest thing would be the
block. You can see the size of blocks on your volumes by tuning the
following command:
tune2fs -l /dev/hda2 | grep -i 'block size'
Where you replace the hda2 with the device name of the partition you
want to look at. According to the ext2 and 3 man pages valid block size
vales are 1024, 2048 and 4096 bytes per block.

The kernel has nothing to do with specific partition format. If you speak
about an ext2 filesystem see man mkfs.ext2 for details.

WTF? Clusters are for Winders. Linux (and all *nixes I'm
familiar with) uses blocksize, which by default is 1KB.
