Dear Dr. O'Neal,
Thank you very much for your respond. I also read from wikipeadia that
ext3 can support up to 32TB with 8KB block size. How can I do it?
As Henrik has pointed out, a DOS partition table is limited to 2TB
single partitions. You can get around this two different ways. The
more involved is actually what many of my systems use - software raid
to combine several partitions into a single file system. If the
underlying partitions are on a hardware raid, you can stripe them
with some performance hit. The second option is to use a sun disklabel
instead of a dos partition, the size limit is much higher in this case.
Use the -b option to mke2fs to set the block size.
mke2fs -n -j -L /scratch -b 4096 /dev/md3
