Erasure coding support for OpenShift Data Foundation (ODF) internal mode helps to enhance storage efficiency and reduce infrastructure costs. Erasure coding enables more space-efficient data protection compared to traditional replication, making it an ideal solution for customers seeking scalable and cost-effective storage.

For more information, see the knowledgebase article, RBD and CephFS Erasure Coding in Internal Mode.

The odf dr tool provides streamlined validation for disaster recovery setups and protected applications. This tool reduces manual effort across clusters and enables faster, more automated issue detection and reporting.

This update enhances control over object quotas by optimizing the timing of size calculations. Previously, enforcement relied on a 2-minute statistics cycle, which could allow excessive uploads and risk storage exhaustion. The new approach reduces latency in quota checks, enabling more responsive and accurate enforcement.

For more information, see Quota support for OBC provided by ODF Multicloud Object Gateway.

Support for incremental snapshots in RBD volumes improves snapshot performance and storage efficiency. Unlike full snapshots, incremental snapshots capture only the changes since the last snapshot, reducing both time and storage overhead.

For more information, see the knowledgebase article, Configure external-snapshot-metadata sidecar container for RBD deployment.

PV-level health monitoring provides detailed status for individual persistent volumes. This enhancement helps administrators to more easily detect and diagnose issues, which can improve operational visibility and reduce troubleshooting time.

For more information, see the knowledgebase article, Enabling VolumeCondition reporting for CephFS PersistentVolumeClaims.
