current setup: RS2BL080 - Supermicro 24port SAS backplane and 5pcs 2TB HDD. All HDDs are configured as RAID5. Now I would like to expand my drive group with additional 4pcs 2TB HDDs. Before I start to do so, I would like to check if that's possible and how much time would it take to carry out this operation? Is data backup advised?
Thanks in advance!
