Doc Type: Bug Fix
Doc Text:
Cause: When a server is set to boot from volume, and an image ID is passed, CAPO creates the root volume prior to creating the server. The root volume is set to be destroyed when the associated server is destroyed. However, if the server fails to create (notably because of quota limits), the volume is never associated to a server and the automatic deletion is never triggered. Consequence: When Server quota limit is hit, at every round of server creation retry, a new volume is created, possibly until volume quota is reached (or server creation is successful). This results in a leakage of unused volumes. Fix: With this fix, a newly created root volume is explicitly deleted as soon as the server creation call fails. Result: When server creation fails (notably because of quota limits), the pre-created root volume is deleted before the next retry.
