Can't Delete Files on Drobo 5N (Mac)

I have a file which got saved to my Drobo 5N, off of my Mac. The filename is:

Just_say_yes._Sometimes_that_spontaneous_gut_instinct__screaming_at_you_to_just_try_something_you_would_normally_shy_away_from_that_insane_20_seconds_of_courage__is_what_memories_are_made_from._Some_of_the_most_incredible_moments__memories_and_friend.jpg

Yes, I know it’s a hideous file name, it got saved accidentally when I wasn’t paying attention. In any case, I cannot remove the file either via the Finder, or going to terminal and doing an rm or even sudo rm. When I try the rm command, I receive an invalid argument regardless of if I put the file in double quotes or not. I can touch the file without issue, but cannot rm or mv the file. Any ideas on how to get rid of it?

Install ssh on the 5N, then use mv or rm once you login.

Also, from terminal have you tried using a wildcard? e.g. rm Just_say_yes*
