- When changing from one version of PBS using one type of vnode create versus another, you must first:
- Quiesce the system (ensure there are no running jobs).
- Remove all existing vnodes of the vntype cray_compute. The easiest way to do this is to delete all vnodes using
- qmgr -c "delete node @default"
- Stop the version of the mom that create vnodes per NUMA node
- Start the new version of MoM that will create vnodes per compute node
- All moms on a Cray X* system must be of the same PBS version.
- On the server add the MoMs back using qmgr: qmgr -c "create node <mom name><output of hostname for the login node you are trying to add>"
