mysql - Cloud SQL second generation - Unable to create failover -

i've created failover replica using cloud sql second generation, had delete , create 1 after few hours, prompts following message:

"there instance name." 

i using same name of failover deleted earlier, changed name error occured:

"could not complete operation." 

now after deleting first failover i'm unable create 1 using same database...

anyone got ideas on this?

thanks!

this behavior indeed expected: 1 may reuse instance name, not right away. instance name unavailable week before can reused.

however, 1 cannot replicate second try: creating failover different name. here, procedure work , differently named failover database created successfully.

more detail on gcloud commands or gui menus steps followed might bring light on matter.
