I’m currently using 4 x 4 TB HDD in Raid 5 setup on PR4100. I am retiring this unit as a backup NaS and want to take out one of the drive (for my new NaS).
I do know that by taking one drive out, RAID 5 will continue to work at reduced performance while keeping 12 TB space and no data redundancy.
So is there a way to convert back into 3 HDD Raid 5 setup (8TB space)? Is this kind of migration supported in OS5?
My data is only around 6TB at the moment so space shouldn’t be an issue.
