Hello.
I have F8 SSD Plus, in 1 and 2 slots installed two Samsung 980 Pro 2 Tb as TRAID.
I'm planning to replace both disks by two another with higher capacity.
How I can do it correctly without data loss and reinstalling system?

PS: All other slots busy by data volumes.

Where is the operating system installed {system drive(s)}

Please refer to the operation instructions in this post to replace the hard drives for expanding the RAID array, replacing one hard drive at a time. viewtopic.php?t=8036
When replacing, ensure that at least one hard drive is used as the system disk first. After replacement, you can migrate the system to the new hard drive and then replace the second hard drive.

I don't know where.
Here are screens:
Both of Samsung marked as System disk, and they added to one volume 1 in TRAID:

It doesn’t matter that both disks are marked as system disks. You can still perform the online expansion by following the method above. When replacing, ensure that at least one hard drive is used as the system disk first. After replacement, you can migrate the system to the new hard drive and then replace the second hard drive.
