Gen 2 Drive help needed

I’ve got three 4TB drives and one 2.5TB drive in there. I’m getting this YELLOW WARNING on one of the 4TB drives: “Drobo is running low on protected space. Replace the hard drive indicated by the yellow light with a larger capacity hard drive.”

Of course, I cannot put in a larger capacity drive because my Drobo accepts only 4TB drives max. Will it serve the same purpose if I replace the 2.5TB drive with a 4TB drive?

Thanks in advance for your help.

Yes, it should help. For some strange reason the Drobo doesn’t always point you to the smallest drive when asking for more capacity.
