DroboFS running low on protected space ... which disk to replace

Hi there,

I’m back again with a question. I have the following drivers:

4TB, 3TB, 3TB, 4TB and 5TB

and running out of protected space (I have double redundancy enabled.

At the moment I cannot verify what I am saying, but as far as I remember the disk which has the yellow light is NOT one of the 3TB disks (but I might be wrong).

In case what I am saying is correct, do I have anyway to replace the disk with the yellow light or I can choose one with the lowest capacity ?

Clearly my idea is to replace the one 3TB with the newest 6TB which I bought (and verify if this one is properly supported).

Thanks a lot in advance.

Stefano
