Is my OS block size 4096 or 512 bytes?

Hi!
I am working on RHEL 4.5 ES edition. I have an installation of an Oracle 10g database whose files spread out over two separate partitions /u01 and /u02 that show a block size of 4096 using dumpe2fs.

dumpe2fs /dev/sdb1 | grep 'size'
dumpe2fs /dev/sda7 | grep 'size'

Block size: 4096
Fragment size: 4096
Inode size: 128

Using a different method of deriving the OS block size by querying v$archived_log I get the output of 512.

Is the v$archived_log method of finding the OS block size incorrect?

Thanks and Regards,
Aniruddha
