System disk issue

[ZiEg]

Dear all,

I am facing an issue I cannot get rid of.
My motherboard has 6 SATA ports (model in ma signature) and I use 7 SATA Disks in my NAS (1 for the system and swap and 6 for storage)
So I had to add a PCI card with 4 SATA ports (for future extension)

My problem is that my system HDD cannot be ada0 so as soon as I format the ada0 drive (storage drive) I receive a message : " Error cannot format the OS Drive"
I know it is possible to fix a certain drive to ada0 in a config file (in UNIX) using its UUID number.

The solution would be that one for me but I dont know :
1. is it feasible on FreeBSD
2 If it is, what is the file to be changed

Many thanks for your help
Regards

did you press clear config and import disks in the disk managment?

Sure I did.
The thing is that the PCI SATA card bring ADA0 - 4 according to the number of drives connected on it.

So tried to put my System disk on it. System was starting to boot and then failed with a rootmount request. I tried all my drives (just in case of) and all storage drive sent an error code 22 when the system drive returned a code 19.

As rootmount I entered ufs:/dev/adaX (X from 0 to 6).

Now I am lost. because I cannot create my Raids ( 3x Raid0 composed of 2 drives and then a Raid5 composed of the 3 Raid0 )

is there a reason why you are using a system disk instead of the recommended usb embedded install?

Yes.... and no....

Previously, I was on an embedded version but I had to install PHP and MySQL. I tried through a jail and it was really problematic.
So I went to a full version and now my databases and my webserver are working really well. So if I have to rebuild everything and face again the issue .....

As I said, I am rather confident to find a file where you can fix ada0 to a certain HDD like eth0 to a certain network card.... which will be much more than good for my case

May have a part of the solution....

Anyhow, if you are asking that in order to get rid of the PCI card, it is useless as my NAS will continue to grow with 3 other HDD soon (6+4 = 3*3 +1); So I really need to sort this out to be able to continue my upgrade path

are you using zfs?

It is more or less what I found b0ssman... The labeling concept. But it does not fix the peripheral name (ada0, ada1, ada2, ....) but only the name
And no I am not using ZFS because I can't find a tutorial for the dummy I am with ZFS
