I saw that the remaining maps could lead to problem,=20 but in 2 words, what are the other associated risks ? Basically If I us= e=20 2 distincts config files, with differents & non-overlapping paths, and different ports for OSD,=20 MDS & MON, we basically have 2 distincts and independant instances ? By the way, is using 2 mon instance with different ports supported ?
