dbCreated is set to false even when db already exists, which results in that tablet start always try to creeate the db. (credit to @vmogilev )

Deployment Notes

Many test failures are related to InitShardPrimary:

, err exit status 1

so looks like the fix has some side effect
however, I deployed a build with this change and tried InitShardPrimary or PRS, neither of them failed,

as we found out the root cause of the long reparenting time was not caused by this bug, and upstream filed an issue for this vitessio/vitess#17521. Going to close this one.
