My system volume is filling up with files "chunk-000xxx"
As stated in Subject.
My md0 went from stable 38-45% to 67% over night.
Did an mount on the system volume and checked and found lots och files named chunk-00001 and so on.
Is it safe to delete those files?
Can anyone point me in the correct way so i maybe can find the issue?
Or do i need to purchase a support ticket for this?
It's an old legacy pro busissinies 6 running os 6.9.2.

Yes.
Second: i forgot how to access disktests and will my data be altered or destroyed if i run them?
Click on the settings wheel for the volume (on the volume tab). The tests aren't destructive (unless of course disks fail when they are run).
There are several maintenance functions in there (defrag, balance, scrub, disk test). You might consider setting up a regular schedule to run them. I run each of them once every 3 months.

It's an old legacy pro busissinies 6 running os 6.9.2.As you know, this combination is not supported, so you will not be able to use paid support.
I suspect the system is finding some corruption in the btrfs filesystem. If you don't have a backup, you should definitely make one.
It might also be wise to test the disks - either using the built-in disk test, or by connecting them to a windows PC and using vendor tools (lifeguard for western digital, seatools for seagate).
Thanks for the answer.
