I have a Drobo version 2 connected via Firewire 800 to my iMac on Snow Leopard.
I previously had four hard drives in it:
In use: 4.3TB
I decided I would like to move some data onto a standalone drive so removed the 1.5TB drive. This meant the Drobo started asking me to insert a new drive as I had nearly 4.3TB of data on the three 2TB drives, too much. So I copied lots of data off the Drobo onto the standalone disk and now have 3.16TB of space used on the Drobo.
The problem I now have is that it won’t reshape, and sits there coloured red saying it can’t protect against failure.
I had an old .5TB drive that I thought might help the situation so I plugged that into the spare Drobo slot and unfortunately it still won’t reshape or protect against a hard drive failure. It looks like this now:
In use: 3.16TB (stated capacity - 4.07TB)
What can I do to make the drive reshape and reprotect my data? Is there something I can do to kick this process off? Do I need to replace the 0.5TB hard drive with another 1.5TB hard drive as this is impossible - if this is the case will I now lose data if I try to swap the 0.5TB hard drive as the data has partially been moved to the 0.5TB drive?
