cannot mount a newly formatted HAMMER2 volume ... mount: invalid argument

I already coded an installation script from scratch which wipes out the drive and formats everything as needed given some parameters. So far so good. Everything is working as expected. But when I attempted to start copying the system files as advised in the manual installation on the handbook, and closely following what the installer script is doing (being previously run the way I expect to install my system with this script), I hit an issue while mounting the already formatted ROOT partition on the BSD slice; ie: da0s1 in my case.

mkdir '/mnt/tempROOT/'; ### a temporary mount point to install the files to be discarded afterward

mount_hammer2 '/dev/serno/CVCV2034019Y180EGN.s1d' '/mnt/tempROOT/';
mount: Invalid argument

dmesg; ### last relevant entries only (full dmesg output at the end of this mail)

...
hammer2_mount: '/dev/serno/CVCV2034019Y180EGN.s1d at ROOT'
hammer2_mount: dev="/dev/serno/CVCV2034019Y180EGN.s1d" label="ROOT" rdonly=0
hammer2: using volume header #0
hammer2 mount "/dev/serno/CVCV2034019Y180EGN.s1d":  no recovery needed

And obviously '/dev/serno/CVCV2034019Y180EGN.s1d' was already successfully formated using:

newfs_hammer2 -L 'system' '/dev/serno/CVCV2034019Y180EGN.s1d';

... with no issues reported at all. Nothing of what I'm seeing in the dmesg outputs tells me anything useful given my (lack of) knowledge right now.

The installer scripts formats ROOT with the -f switch (it really formats all HAMMER2 volumes with -f) but the man page for newfs_hammer2 states that it should be used when the volume size is <= 10 GB which in my case applies to /boot and /build.

The installer (as shown in its log) is doing:

,-<<< Executing `/sbin/mount_hammer2 /dev/serno/CVCV2034019Y180EGN.s1d /mnt/'
`->>> Exit status: 0

I am using another mountpoint but I can't see why it could make any difference.

Am I doing anything wrong ?

PS: by the way: the target drive in question is:
da0: <SATA INTEL SSDSC2CW18 400i> Fixed Direct Access SCSI-4 device 
da0: Serial Number CVCV2034019Y180EGN
da0: 150.000MB/s transfers
... which dragonFly sets/uses @ 150 MB/s but the drive is SATA @ 6 Gbps ... any clues ?

Following is everything I expect it could be of some help (I don't know yet what command could report the status or some info on unmounted partitions on any given slice; eg: da0s1 containing 4 partitions with their own file-systems in my case):

gpt show da0;
