Thank you for the response. The first
is insignificant, but there is ½ a terabyte missing on the second which is
listed as 8192 EB? It should be ~500 GB free? Thanks! From:

Of pham_cuong@emc.com When you format, unless you specify the block size, the default
block size is used. The default block size is defined based on the size of the logical
disk (partition) size that you've created. Any disk space left over from the format is listed as unusable (for
the block size that's being used) can not be used because it's not a multiple
of the block size used to format that logical drive/partition. The only way that you can make use of the remaining very small disk
space is to use the smaller block size when formatting. However,
unless you know exactly what you're doing, it's not advisable for you to do so
since this will more likely impact the performance of your logical
drive/partition. A lot of testing were done to determine the optimal
block size based on the size of the logical drive/partition that you've
created. Except for academic reason(s), you should not be concerned with
such a small left over. Regards, From: linux-lvm-bounces@redhat.com
