Hi! Don't you need 10 constraints, excluding every possible pair of your 5 resources (named A-E here), like in this table (produced with R):
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,] "A" "A" "A" "A" "B" "B" "B" "C" "C" "D" [2,] "B" "C" "D" "E" "C" "D" "E" "D" "E" "E" Ulrich >>> Nikhil Utane <nikhil.subscri...@gmail.com> schrieb am 13.10.2016 um 15:59 in Nachricht <cagnwmjw0cwmr3bvr3l9xzcacjuzyczqbzezuzpajxi+pn7o...@mail.gmail.com>: > Hi, > > I have 5 nodes and 4 resources configured. > I have configured constraint such that no two resources can be co-located. > I brought down a node (which happened to be DC).
