Ulrich, I have 4 resources only (not 5, nodes are 5). So then I only need 6 constraints, right?
[,1] [,2] [,3] [,4] [,5] [,6] [1,] "A" "A" "A" "B" "B" "C" [2,] "B" "C" "D" "C" "D" "D" I understand that if I configure constraint of R1 with R2 score as -infinity, then the same applies for R2 with R1 score as -infinity (don't have to configure it explicitly). I am not having a problem of multiple resources getting schedule on the same node. Rather, one working resource is unnecessarily getting relocated. -Thanks Nikhil On Thu, Oct 13, 2016 at 7:45 PM, Ulrich Windl < ulrich.wi...@rz.uni-regensburg.de> wrote: > 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).
