OSSFS configurations are incompatible with csi-plugin 1.26.6 and 1.28.1 and csi-provisioner 1.26.6 and 1.28.1. Before you update csi-plugin and csi-provisioner to 1.26.6 or 1.28.1, we recommend that you read the Scope of impacts section.
Scope of impacts
If OSSFS configurations are configured based on the /etc/mime.types file generated by using mailcap or mime-support in csi-plugin and csi-provisioner versions earlier than 1.26.6, the OSSFS configurations do not take effect after you update csi-plugin and csi-provisioner to 1.26.6 or 1.28.1. As a result, you cannot upload files to Object Storage Service (OSS) or delete files from OSS.
Solution
If your cluster meets the following conditions, do not update csi-plugin and csi-provisioner to 1.26.6 or later. The Container Service for Kubernetes (ACK) team will fix this issue at the earliest opportunity. We recommend that you pay attention to the release notes for csi-plugin and csi-provisioner. For more information, see csi-plugin and csi-provisioner.
