Description

The following improvements are asked for from users related to cluster directory handling:

• Create a new cluster directory if one does not exist.
• If a cluster directory points to a dead cluster, currently allocate fails with a message asking user to deallocate it first. Instead, it should issue a warning, deallocate the cluster and automatically allocate a fresh one.
