I am playing again with my little DF NAS project tonight after almost 5
days of break due to a flu. Apparently my brain was not working last
time around since I have no problem locating Adding a Disk section in
the Handbook. It is under the UNIX Basics chapter section 8
https://www.dragonflybsd.org/docs/handbook/UnixBasics/
In the mean time I did end up reviewing everything about Slices (also
fdisk and gpt utilities) as well as Partitions (disklabel32 and
disklabel64)
No interestingly enough putting two used HDDs into my NAS I can
immediately see
dfly# ls -l /dev/serno
total 0

without even using gpt. Would that be the case if I had 2 brand new
HDDs? I was able to create HAMMER file system on one of them
newfs_hammer -L data /dev/serno/WD-WCAWZ2111282
even after running
gpt destroy /dev/ad8 (that is actually WD-WCAWZ2111282 drive). That is
probably the reason I don't remember messing up with gpt and disklabel64
when I played with this few months ago in the VirtualBox. I also get
swapcache suggestion for the SSDs.
