My apologies. I was originally attaching the results of "gpart show" as =
a screenshot because I was working through an internet kvm module on a =
system several states away that was booted in standalone mode. But the =
mailing list seems to strip off attachments, so I ssh'd into the system =
in normal operation to get output of "gpart show" that I can cut and =
paste here.

Subject: Re: Expand partition size after a raid array increase=20
I have a freebsd box with an LSI Raid controller in it. It had 4 =
3-terabyte=20
drives configured in an 8TB array. I added a 5th drive and built that =
into=20
the array. Of course, the amount of drive space that shows in operation =
in=20
FreeBSD did not change, presumably because I need to resize the =
partition.
I was trying to follow the partition resizing instructions shown here =
---
http://www.unibia.com/unibianet/freebsd/resize-your-existing-freebsd-root=
-partitionslice-safely-without-re-installing
but when I do the =E2=80=9Cgpart show =E2=80=9D I don=E2=80=99t see the =
free space. What I do see is=20
a change in the apparent overall size of the disk and a set of =
parititions=20
that don=E2=80=99t add up to the new size of the disk.
How should I be going about increasing the size of the partition?

Your GPT partition table is showing up as corrupt. Is there anything in
dmesg about that? Maybe your device has grown, and you just need to repair
the GPT partition (gpart recover mfid0) to reflect the larger size. Also,
try running "diskinfo -v mfid0" and see whether that shows the new size.
Note that the instructions you linked to use MBR and BSD disklabels instead
of GPT; neither MBR or BSD store the device size or store metadata at the
end of the device, so if their provider grows, they can immediately take
advantage of the new space. GPT stores a backup copy on the last sector,
and refers to that location in the primary copy, so you always have to fixup
your GPT every time you resize a device.
