are only shown as ada0 and ada1 but no partition devices, no devices in /dev/gpt/ or /dev/gptid/, these directories are completely missing even though there are GPT labels.
This is FreeBSD 13.2-RELEASE-p5 amd64 on HP Microserver Gen8. Disk are 2 Seagate NAS 4TB, manually partitioned with gpart utility, zpool created and then all the date migrated by zfs send and zfs receive from old 2TB disks. Everything works, system is running but device nodes in /dev/ are missing. I noticed this only when I want to create gmirrored swap from
ada0p4 and ada1p4 but got "No such file or directory."

There are only diskid style devices in /dev/diskid/

Sysctl seems normal to me.

# sysctl kern.geom.label
kern.geom.label.disk_ident.enable: 1
kern.geom.label.gptid.enable: 1

What can be wrong with this system?
