ok.

let me provide the partitions up front
root@zfs1:/home/ck # gpart show /dev/ada0
=> 40 468862048 ada0 GPT (224G)
40 1024 1 freebsd-boot (512K)
1064 134217728 2 freebsd-swap (64G)
134218792 33554432 3 freebsd-vinum (16G)
167773224 33554432 4 freebsd-vinum (16G)
201327656 267534424 5 freebsd-zfs [bootme] (128G)
468862080 8 - free - (4.0K)
root@zfs1:/home/ck #
ada1 is essentially the same.
These are the two m2 ssd I have zroot und zil on.
The two freebsd-vinum partitions used to be freebsd-zfs
Partitions 3 and 4 are used for the log device and these happen to have the names I was getting confused about
root@zfs1:/home/ck # zdb -l /dev/ada0p3 | head -10
------------------------------------
LABEL 0
------------------------------------
version: 5000
name: 'zp1'
state: 0
txg: 37392274
pool_guid: 6725164972097052508
hostid: 694021601
hostname: 'zfs1'
root@zfs1:/home/ck #
root@zfs1:/home/ck # zdb -l /dev/ada0p4 | head -10
------------------------------------
LABEL 0
------------------------------------
version: 5000
name: 'zp2'
state: 0
txg: 21037796
pool_guid: 16088850666393843588
hostid: 694021601
hostname: 'zfs1'
root@zfs1:/home/ck #
It is just a name and not a label. gptzfsboot was trying to tell me it cannot boot from ada0p3 which has the name zp1.
My two other pools on the sas hba happen to be called zp1 and zp2.
For some reason when I setup the system I moved stuff around and ended up with two zlog partitions first and the zroot last.
So now everything makes sense again.
The freebsd-vinum hack solves this for me and I have gained some more experience.
In the future I will ensure to have the first partition after boot to be the zroot.
Greetings
Christian
