| I am trying to setup 3 MDS servers (one on each MON) but after I am done setting up the first one, it give me below error when I try to start it on the other ones. I understand that only 1 MDS is functional at a time, but I thought you can have multiple of them up, incase the first one dies? Or is that not true?
