CONTAP-746927: S3 Operations Can Fail with “Access Denied” on FlexCache Buckets After an ONTAP Upgrade
Issue
After an ONTAP upgrade, S3 operations such as
PutObject may fail with an “Access Denied” error on S3 FlexCache buckets. This can occur when the origin volume was created on an earlier ONTAP release, the FlexCache volume and bucket were created after the upgrade, and S3 access to NAS FlexCache volumes is enabled.
