Hello,

I try to prevent auto-migration back from mds2 to mds1, but somehow resource-
stickiness doesn't seem to work. After a failure of mds1 and takeover on mds2, 
it still migrates back to mds1 when this system comes back

primitive MDT_HC3WORK ocf:ddn:lustre_server \         
        params device="/dev/vg_HC3WORK/mdt" directory="/lustre/HC3WORK/mdt" \
        op start interval="0" timeout="700" \                                
        op stop interval="0" timeout="600" \                                 
        op monitor interval="120" timeout="600" \                            
        meta resource-stickiness="200" is-managed="true"    

                 
property $id="cib-bootstrap-options" \
        default-resource-stickiness="200" \
        no-quorum-policy="stop" \
        dc-version="1.0.6-f709c638237cdff7556cb6ab615f32826c0f8c06" \

MDT-HC3WORK is also part of a resource group, but the resource group and also 
all member do have the very same location constraints. Is is my mistake or a 
bug? 


Thanks,
Bernd
