Drobo FS not mounting, tried everything

Drobo FS stopped mounting, have run Repair many times, half of the times it mounts again, but as soon as I start to backup the contents it “unmounts”, stopping all transfers. What else can I do to get my contents and Reset the drobo?

Did you ever get anywhere with this? I’m having an issue with a volume not mounting. How are you running repairs on an unmounted volume? Thanks!
