Diagnosing "No Compute Resources Available" messages in Triton.

No Compute Resources Available

This error is somewhat ambiguious because there is seemingly no indication which resource is exhausted.

Triton chooses compute nodes with a subcomponent called sdc-designation (also refered to as , DAPI). The full DAPI log for a provision job is embedded in the CNAPI log file and can be extracted with the workflow job uuid.

Note: The script below is no longer necessary because cnapi now includes /opt/smartdc/cnapi/bin/alloc-reasons.sh which does the same thing.
