I have a strange situation. Because of this, I now have NO REDUNDANCY, so any help is appreciated…
In my DroboPro I had 5x 1TB, 1x 1.5TB and 1x2TB. All drive lights were green, single-drive redundancy and (only) 1.5TB of data on the (single) volume.
So I decided to remove the 2TB drive, and replace it with a spare 1TB drive. Obviously, when I removed the 2TB, drivelights started blinking green/orange, but soon after stopped. Then all occupied drive bays were solid geen, and the left-most empty bad was solid red. DroboPro’s standard way of asking for an extra drive.
Question 1: Why would it need an extra drive if I have 1.5TB data and 5x 1TB + 1x1.5TB? I had single-drive redundancy, but even on duad-drive redunancy I should have 4TB available. By far enough for my 1.5TB, no?
So I added the 1TB drive, which made it 6x 1TB + 1.5TB. But still it’s asking for another drive (in the 8th bay).
I have the feeling it has to do with the 2TB which was the biggest drive in the set, that I removed. Maybe the 0.5TB extra space that only this drive had, now needs to be replicated to other disks. But then I would expect green/yellow blinking lights.
Questions 2 & 3: What’s happening, and how can I fix this so I have redundancy again?
