Products

• VMware vCenter Server

Issue/Introduction

• Deleting an empty vCenter cluster results in a vCenter vmware-vpxd service crash, and clusters cannot be deleted.
• vpxd logs:

Environment

VMware vCenter Server 7.x

Cause

The vmware-vpxd service may crash or hang if a stale or duplicate entry exists for the empty clusters in vpx_compute_resource_drs_vm table in the VCDB.

Resolution

• SSH into the vCenter as the root user
• To find the affected cluster ID 
  • psql -h localhost -U postgres -d VCDB -c "select * from vpx_entity where name = '<affectedclustername>';"
• To find any stale drs rules related to that cluster
  • psql -h localhost -U postgres -d VCDB -c "select * from vpx_compute_resource_drs_vm where comp_res_id =  '<TheIdNumberFromAbove>';"
• To find the VM name of the vm ids listed
  • psql -h localhost -U postgres -d VCDB -c "select * from vpx_entity where id = 'TheVMIDFromAbove';"
• Unregister this VM from inventory.
• Delete the empty cluster.
• Re-register the VM.
