I have a system with 4 3TB hard drives in a softraid(4) RAID 5 array. I would like to expand the array to use much larger hard drives. I could offline one drive, replace it with a larger drive, and then create a new 'd' RAID partition of the new size (with fdisk(8) and disklabel(8). Then I would initiate a rebuild. Once that was done on all four drives, would it be possible to modify the sofraid(4) volume's fdisk and disklabel so I could use growfs(8) to increase the size of the softraid(4) RAID 5 volume?
I came across a thread asking about this exact issue for a softraid(4) crypto volume and it was not possible to expland the softraid(4) volume in that case. I am guessing that the same is probably true for RAID 5 but I am hoping that I may have overlooked something. Thank you. Bryan
