RE: Expand virtual disk size in Raid 1.
I did not replace the drives, I added two 1 T drives. I now have 4 drives, 2 500M and 2 1T. Looking in Openserver manager i see Virtual Disk 0 is noted at 1.8 T. The 2 physical drives show capacity 4.6 and 2 show 9.6 (or close I am not where I can read the actual numbers) and all 4 show RAID capacity at 4.6. So, there is unused capacity, but I expected that. I wanted to get 500M disks, but was offered 1T. Took the offer.
