I’ve had a Drobo 5D for a while and it was initially set up with five WD 2TB drives. My drives are NOT set up for dual-disk redundancy. Recently, one of the bay lights turned yellow (low on capacity), so I decided to replace that one 2TB drive with a new 4TB drive. That happened again a few months ago; I now have two 4TB drives, and three 2TB drives. When I click on the Drobo in the dashboard, it says “There is a new volume on your Drobo device that needs to be formatted. Would you like to format it now?”
If I say “yes”, it proceeds to ask me for a new volume name and wants to format another 8TB.
I’m confused. I thought when you hot-swapped drives in a Drobo, it automatically formatted the new drives. I’m reluctant to let this proceed for fear that it’s going to reformat everything and I’m gonna have 5 clean drives. Obviously, I don’t understand how all this works.
Under “Volumes”, it shows the volume ID=0 as HFS+ (I’m using Mac) with 6.44TB used, 8TB max. Under the new volume ID=1, it shows “not formatted”, nothing used, and 8TB max.
Can someone shed some light here before I click “next”, and lose everything ?
Also, I’m planning on swapping out two of the other 2TB drives with 6TB drives to boost capacity and give myself some breathing room for a while.
