A general controller error occurred. Connection refused while powering on virtual machine



Recently I had an issue where I was trying to power on a VM from vCenter but unable to power on.
While powering on getting below error.

“A general controller error occurred. Connection refused.”



VCenter server which Im running is 6.0 and on appliance (VCSA).

Steps I follow to resolve the issue:

While investigation I found it’s a issue of Workflow manager service which was causing VM to start from vCenter. However, I was able to power on the VM from ESXi, which shows that the issue is not with VM or ESXi . It’s the issue with the services of workflow, which are not allowing VM to poweron from vCenter.

I tried below steps to verify the status of the VMware vCenter Workflow Manger service from VCSA.

1) Login to VCSA via Putty.
2) shell.set --enabled True
3) service-control --status vmware-vpx-workflow
Status of the services was showing stoped, So, I tried to start the service by using command.
service-control --start vmware-vpx-workflow.

I was getting error while starting the workflow services.

Now I tried to verify the disks space of VCSA by using df –vdf. Where I found that the space is about to 100% at /storage/logs disk. Removed the unwanted data from this location and make some space to breath.

Later I again try to start the vmware workflow services and its started successfully and by that VM from vCenter was able to poweron without any issue.



Happy Sharing.... :)
