name of SSD drive suddenly got renamed.

The name of my ssd drive was "/dev/nda0".
Now it's name is "/dev/diskid/DISK-22080H803652" & "/dev/nda0" has gone.
I only changed the bootloader to arch-grub linux.
Can i revert this ? E.g. with a sysctl setting ?
 
I suspect it's grub's doing, it probably refers to the disk by its diskid. Then kern.geom.label.gptid.enable and/or kern.geom.label.gptid.enable in loader.conf hides /dev/nda0.
 
Not grub, but more likely ZFS. Geom hides the aliases when one of them is opened. Since ZFS prefers disk IDs to simple names on pool creation, this is the side effect.

If you post a full dmesg i can confirm.
 
zfs/zpool continue working. It's like it does not care lot about device naming.
Changing "kern.geom.label.gptid.enable" looks dangerous as i want freebsd to continue to boot.

To my knowledge it does not. When it comes up or runs, it looks over all the attached block devices (with some rules).

Is there a handbook section that explains /dev/[a]daX versus /dev/gpt/xxx versus /dev/diskid/...?

What's the value of the bootfs property of your boot pool?

Here, I have:

Code: 
% zpool get bootfs august
NAME    PROPERTY  VALUE                        SOURCE
august  bootfs    august/ROOT/1500018-32-base  local

I have no line "kern.geom.label.gptid.enable" in loader.conf.

It's a strange and weird "mixture" ...
 
This looks to me you have OpenZFS pools imported on (Arch?)linux.

sdc1, sdd1, sde, those are Linux device naming.

Not in the handbook, but FreeBSD Mastery: Storage Essentials by Michael W Lucas has a good explaination.

/dev/gptid is based on the globally unique identifier attached to each gpart partition on creation
/dev/diskid is based on the disk serial number
/dev/gpt is based on any label given when creating the partition using gpart
/dev/mirror is based on GEOM mirror

And yes ZFS attaches it's own metadata
