Chapter 3. Enhancements
This section describes the major enhancements introduced in Red Hat OpenShift Data foundation 4.16.
3.1. New elements for bucket policies
OpenShift Data Foundation now has the bucket policy elements, NotPrincipal, NotAction, and NotResource. For more information on these elements, see IAM JSON policy elements reference.
3.2. Addition of a new AWS region to the Multicloud Object Gateway Operator
A new AWS region, ca-west-1, is added to the supported regions of the Multicloud Object Gateway (MCG) operator for the creation of default backingstore.
3.3. Increase in resource allocation for OpenShift Data Foundation Multicloud Object Gateway BackingStore
The default resources for PV pool CPU and memory are increased to 999m and 1Gi respectively to enable more resource allocation for OpenShift Data Foundation MCG BackingStore.
3.4. Multicloud Object Gateway created routes to work with HTTPS only
For deployments that need to disable HTTP and use only HTTPS, an option is added to set DenyHTTP to the storage cluster CR spec.multiCloudGateway.denyHTTP. This causes the Multicloud Object Gateway created routes to use HTTPS only.
3.5. Addition of protected condition to DR protected workloads with metrics and alerts for monitoring
Protected condition to DR protected workloads is added by summarizing various conditions regarding the DR protected workload from the ManagedCluster, and metrics and alerts are generated based on the same.
DR protected workload health at the hub is reflected based only on the time when contents of the respective PVCs are synced. This applies only to RegionalDR use cases and not to MetroDR use cases. On the ManagedCluster, the workload DR protection health is expanded into several conditions. This makes it non-trivial for a user to monitor the workload DR health across these conditions. This added protected condition and alerts helps better workload DR protection monitoring.
3.6. Support for listing multiple uploads in NamespaceStore Filesystem
You can now list the files that are still uploading or list incomplete multipart uploads in NamespaceStore Filesystem by using the following command:
$ s3api list--multipart-uploads --bucket <bucket_name>
3.7. Option to modify thresholds for Ceph full, nearfull, and backfillfull attributes
Depending on the cluster requirements, the full, nearfull, and backfillfull threshold values can be updated by using the odf-cli CLI command.
For example:
odf set full <val>
odf set nearful <val>
odf set backfillfull <val>
The value must be in the range of 0.0 to 1.0 and you need to ensure that the value is not very close to 1.0.
