I answered part of your question on the other post for the same topic.
Here is a site that may help you tremendously. Look in chapter 4.
http://www.redbooks.ibm.com/SG245139/5139fm.htm
For most OSs, I believe I can say that 4mb is the default size for OS filesystems. To see your block size, you should be able to run a command on the volumes/slices. On HPUX it is something like "vgdisplay -v /dev/vg01/lvol". The information at the top will show it. Do a "man -k block" to find your command in your man pages.
You can set the blocksize when you create new filesystems. It can't be changed once you have created a volume/filesystem. You would have to backup the data and destroy and recreate the filesystem to change the block size.
You will have to create new filesystems to migrate data to or backup and recreate the ones you have.

Accordingly a lot of manuals - if you have block size 8KB and trying to write a 1KB file to the block, as result you waste 7KB of the block space.

sys::filesystem::aix
Sys::Filesystem::Aix(3pm) User Contributed Perl Documentation Sys::Filesystem::Aix(3pm)
NAME
Sys::Filesystem::Aix - Return AIX filesystem information to Sys::Filesystem
SYNOPSIS
See Sys::Filesystem.
INHERITANCE
Sys::Filesystem::Aix
ISA UNIVERSAL
METHODS
version ()
Return the version of the (sub)module.
ATTRIBUTES
The following is a list of filesystem properties which may be queried as methods through the parent Sys::Filesystem object.
account
Used by the dodisk command to determine the filesystems to be processed by the accounting system.
boot
Used by the mkfs command to initialize the boot block of a new filesystem.
check
Used by the fsck command to determine the default filesystems to be checked.
dev Identifies, for local mounts, either the block special file where the filesystem resides or the file or directory to be mounted.
free
This value can be either true or false. (Obsolete and ignored).
mount
Used by the mount command to determine whether this file system should be mounted by default.
nodename
Used by the mount command to determine which node contains the remote filesystem.
size
Used by the mkfs command for reference and to build the file system.
type
Used to group related mounts.
vfs Specifies the type of mount. For example, vfs=nfs specifies the virtual filesystem being mounted is an NFS filesystem.
vol Used by the mkfs command when initializing the label on a new filesystem. The value is a volume or pack label using a maximum of 6
characters.
log The LVName must be the full path name of the filesystem logging logical volume name to which log data is written as this file system is
modified. This is only valid for journaled filesystems.

* <snip>

* This version of /etc/filesystems assumes that only the root file system
* is created and ready. As new file systems are added, change the check,
* mount, free, log, vol and vfs entries for the appropriate stanza.
