[Ocfs2-users] Maximum volume size for OCFS2?

I apologize for bothering the list, but the information I have found
is contradictory.

According to http://oss.oracle.com/projects/ocfs2/dist/documentation/ocfs2_faq.html#LIMITS
, the maximum volume size is 16TB.

According to http://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits
, it's 4PB.

According to http://ocw.novell.com/suse-linux-enterprise/migrating-from-redhat-to-suse-linux-enterprise-server-10/3068_10_manual.pdf
, it's "4 TB / 16 TB / 4 PB", with no indication of which.

I am using Suse Enterprise Linux 10 SP1 on x86_64.  For my
application, a 16TB volume is not sufficient, but a 4PB volume would
be.

So:

    Can I create a volume larger than 16TB?  If so, is there any
special procedure I should know about?

(Also, one or more of the references above should probably be updated.)

Thank you!
