Hi,

I have installed OpenBSD 7.2 on a 14TB SATA disk using my ODROID HC4.

During installation, I was not able to use the whole disk size
although I selected "whole" and "auto partionning". The installer seemed
to recognized only about 2TB.

dmesg says:
sd0 at scsibus0 targ 0 lun 0: <ATA, WDC WD140EFGX-68, 85.0>
naa.5000cca28fd7d301
sd0: 13351936MB, 512 bytes/sector, 27344764928 sectors

but after rebooting on the installed system, the disk layout was the
following:

# fdisk sd0
Disk: sd0       geometry: 32960/511/255 [4294852800 Sectors]

Using disklabel, I could "correct" the disk usage and reformat the last
partition to get full disk space.

The questions are :
- is this an expected behaviour from the installer?
- shall the disklabel correction rather be done during installation?
- is this a issue when fdisk and disklabel disagree about the number of
sectors?

Thank you,
Joel C.
