I recently added Drives to my Drobo S which creates new volumes once you pass 16TB, I’m now at 35 TB (2x 10TB drives, 3x 5TB drives).
Drobo Vol 1 - Drobo Dashboard shows 16TB max capacity, sounds about right
Drobo Vol 2 - Drobo Dashboard also shows 16TB max capacity - on this I am in doubt.
Drobo Dashboard’s Capacity Tab shows 22.64 TB for Data, most of the rest is for protection, which make sense. What doesn’t make sense is that 16 + 16 = 32TB, and that’s 10TB more than 22. There’s no way both volumes have 16TB of free space, and I can’t really get an accurate read on how much remains.
Finder shows Volume 1 as having 17.59 TB of capacity, and the same for volume 2, with over 15TB available. I was wanting to use this new volume for Time Machine backups, but I don’t know how well that’s going to work if neither I nor Dashboard nor Finder can really tell how much is left in there with any degree of accuracy.
How can I get an accurate read on how much space I have on the multiple Drobo Volumes?
