pvcreate has had some known issues in the past reporting wrong sizes, especially for disks larger than 1 TB.
It has been fixed in most recent RHEL releases. Which version are you using?
As for using raw devices vs partitions I'm gonna quote myself from another post in this forum:
Quote:
Red Hat strongly suggests not to use whole disks as PVs.
Using whole disks increases the risk of an external application overwriting the data under some rare circumstances.
Here's an example of this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=154841
Even though most of those problems have already been patched and fixed in latest RHEL releases, Red Hat still discourages that practice for production/critical systems.
Using partitions of type 8e is the preferred method.

KSC(1) User Commands KSC(1)
NAME
ksc - Linux kernel module source checker
SYNOPSIS
ksc [ -d | --directory ] DIRECTORY
ksc [ -k | --ko ] FILE
OPTIONS
KSC accepts command-line arguments, and has both a long and short form usage. You can use either style or combine them to specify
options. When the tool is run with kernel module sources it checks for all four architectures, and when run with binary kernel modules, it
checks for the specific architecture for which the binary was built.
Valid RHEL whitelist releases are rhel6.0, rhel6.1, rhel6.2, rhel6.3, rhel6.4
-h, --help
show this help message and exit
-c CONFIG, --config=CONFIG
path to the local ksc.conf file. If not specified the tool tries to read from ~/ksc.conf and if that is also not found then from
/etc/ksc.conf
-d DIRECTORY, --directory=DIRECTORY
path to the directory
-i, --internal
to create text files to be used internally.
-k KO, --ko=KO
path to the ko file. You should either use -d or -k to run the KSC tool, but not both. If both -d and -k option is used at the
same time then only -d is used and the -k option is discarded.
-n RELEASENAME, --name=RELEASENAME
Red Hat release against which the bug is to be filed. Default value is 6.5
-p PREVIOUS, --previous=PREVIOUS
path to the previous resultset file and submit it as a bug to Red Hat Bugzilla.
-r RELEASE, --release=RELEASE
RHEL whitelist release used for comparison
-s, --submit
Submits the report to the Red Hat bugzilla (https://bugzilla.redhat.com). The credentials need to be in the /etc/ksc.conf file. The
tool will prompt for bugzilla password.
The configuration file looks like below:
[bugzilla]
user=user@redhat.com
partner=partner-name
partnergroup=partner-group
server=https://bugzilla.redhat.com/xmlrpc.cgi
-v, --version
Prints KSC version number
ksc - Version 0.9.11 Feb 2014 KSC(1)
