Description of problem:
Hi, I have a fresh RH 7.1 (2.4.2-2smp i686) install on a Compaq DL360 with 
the embedded Smart Array controller. 

I have partitioned the remainder of my disks with fdisk and rebooted. I 
now need to setup my extra disks and filesystems with an 8k block size for 
use with an Oracle database.

If I use mkfs.ext2 -b 8192 /dev/ida/c0d0pN it says 8192 is a bad block 
size?!!

I can successfully use mkfs.ext2 -b 4096 /dev/ida/c0d0pN.

I can also successfully use mkfs -V /dev/ida/c0d0pN which uses a 4k 
filesystem blocksize by default. 


How reproducible:
Always

Steps to Reproduce:
1.mkfs.ext2 -b 8192 /dev/<put your partition here>
2.
3.
	

Actual Results:  mkfs.ext2: bad block size - 8192
No filesystem is created.

Expected Results:  It should have created a new 8k block ext2 filesystem.

Additional info:
I suspect this is not RedHat specific, as I get the exact same problem 
with SuSE 7.2 on the same hardware. you may have to check with the 
mkfs.ext2 developer?

Only up to 4K blocksize are supported.
