Migrating an existing RAID 5

#1

As the topic says I want to migrate an existing RAID 5 array. I am upgrading my motherboard on my main system and want to move my RAID 5 array to the Raspberry Pi 5 using a Penta Hat. My new motherboard won’t accommodate my array, and I want to create a separate NAS on the RP5 and Penta HAT. My RAID 5 consists of 4 SATA 2TB drives. I have a question.

Can I migrate my array without losing my data? My data consists of about 2.5TB of media files and isn’t critical if I lose it but would prefer not to. How would I go about the Migration if possible?

Did you create the array using mdadm? If so, it should be possible.

I created the RAID Array with IRST (Intel Rapid Storage Technology) in my Motherboard BIOS with a VMD Controller.
The drives are in hot swap bays and I figure I will just have to connect the SATA cables and see what happens. I can power the RP5 and HAT with my PC Power Supply and stash it in my case.

IRST is a proprietary technology, I don’t think it’s implemented in Linux, especially if you enabled it in the BIOS. It also needs a separate chip to work. I think you can’t migrate. Consider using something open source on the future… mdadm or zfs, you can use these on Linux.
