Instance Task State Stuck in Deleting

Problem

• An instance is unable be deleted (potentially with one or more volumes attached).

• The server details show that the OS-EXT-STS:task_state field is stuck in a deleting state.

Environment

• Platform9 Managed OpenStack - All Versions

• Nova

• Cinder

Cause

The pf9-ostackhost (nova-compute) service may be unresponsive and/or a previous operation failed for the instance (e.g. volume detach).

Resolution

1. Restart the pf9-ostackhost service (which will reset the task state for any pending instances).
