Chapter 3. Major Updates

Support for rebuilding Monitor store from OSD nodes

The ceph-objectstore-tool and ceph-monstore-tool utilities now enables you to rebuild the Monitor database and keyring files from OSD nodes. This ability is especially useful when all Monitors fail at the same time to boot due to an underlying leveldb corruption. For details, see the All Monitors Failed to Start Because of a Corrupted Store section in the Administration Guide for Red Hat Ceph Storage 2.

Collection splitting can be now done offline

This update adds the apply-layout-settings command to the ceph-objectstore-tool utility. The new command enables users to perform collection splitting offline on OSD nodes in cases when doing it online would cause too large an impact.

Ceph Object Gateway now supports static website hosting

With this feature, users can host static websites in Simple Storage Service (S3) buckets. For details, see the Configuring Gateways for Static Web Hosting chapter in the Red Hat Ceph Storage Ceph Object Gateway Guide for Red Hat Enterprise Linux.

Ceph Object Gateway now supports indexless buckets

Indexless buckets do not maintain an index and therefore require much less resources on Ceph OSDs. Consequently, they have higher performance than indexed buckets. Indexless buckets cannot be listed or replicated, therefore use them only when these capabilities are not required. For details, see the Storage Policies chapter in the Ceph Object Gateway Guide for Red Hat Enterprise Linux or the Storage Policies chapter in the Ceph Object Gateway Guide for Ubuntu.

Ceph Object Gateway now supports the Amazon "requestPayment" API call

The Amazon requestPayment API call enables users of a public storage object to provide data publicly without incurring payment for the retrieval of that data by other users.

"rados bench" now shows how much time it took to clean up objects

With this update, the rados bench command output includes a line that shows how much time it took to clean up objects:
