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.
root at warehouse:/root # gpart show mfid0

Subject: Re: Expand partition size after a raid array increase
I have a freebsd box with an LSI Raid controller in it. It had 4 3-terabyte
drives configured in an 8TB array. I added a 5th drive and built that into
the array. Of course, the amount of drive space that shows in operation in
FreeBSD did not change, presumably because I need to resize the partition.
I was trying to follow the partition resizing instructions shown here ---
but when I do the “gpart show ” I don’t see the free space. What I do see is
a change in the apparent overall size of the disk and a set of parititions
that don’t add up to the new size of the disk.
How should I be going about increasing the size of the partition?
