Hi Renfro I am testing this configuration, test configuration and as clean as possible:
==== NodeName=devcn050 RealMemory=3007 Features=3007MB Weight=200 State=idle Sockets=2 CoresPerSocket=1 NodeName=devcn002 RealMemory=3007 Features=3007MB Weight=1 State=idle Sockets=2 CoresPerSocket=1 NodeName=devcn001 RealMemory=2000 Features=2000MB Weight=500 State=idle Sockets=2 CoresPerSocket=1 PartitionName=slims Nodes=devcn001,devcn002,devcn050 Default=yes Shared=yes State=up === In your config is necessary one plugin extra or parameter for option Weight? The configuration does not work as expected.
