Managing and allocating resources

Understand how to create, configure, and allocate storage to core services or hosted applications in IBM Fusion Data Foundation.

Storage classes
Use this information to understand how to create custom storage classes.
Block pools
This section provides you with information about how to configure block pools in internal mode.
Configure storage for OpenShift Container Platform services
Use Fusion Data Foundation for core OpenShift Container Platform services, such as image registry, monitoring, and logging.
Creating Multus networks
Backing OpenShift Container Platform applications with Fusion Data Foundation
Configure OpenShift Container Platform applications to use Fusion Data Foundation.
Adding file and object storage to an existing external Fusion Data Foundation cluster
Add file storage (using Metadata Servers) or object storage (using Ceph Object Gateway) or both to an external Fusion Data Foundation cluster that was initially deployed to provide only block storage.
How to use dedicated worker nodes for Fusion Data Foundation
Use dedicated worker nodes for IBM Fusion Data Foundation
Managing persistent volume claims
Manage and automate the fulfillment of Persistent Volume Claim requests.
Reclaiming space on target volumes
Reclaim the actual available storage space on target volumes.
Finding and cleaning stale subvolumes
This section describes how to find and clean stale subvolumes.
Volume snapshots
Create, restore, and delete volume snapshots.
Volume cloning
A clone is a duplicate of an existing storage volume that is used as any standard volume. You create a clone of a volume to make a point in time copy of the data. A persistent volume claim (PVC) cannot be cloned with a different size. You can create up to 512 clones per PVC for both CephFS and RADOS Block Device (RBD).
Managing container storage interface (CSI) component placements
Set tolerations to bring up container storage interface (CSI) component on the nodes.
2-way replication with CephFS
To reduce storage load with the Ceph File System (CephFS) when data resiliency is not a primary concern, you can choose to use 2-way replication (replica-2). It reduces the amount of storage space that is used and decreases the level of fault tolerance.
Creating exports using NFS
Create exports using NFS that can then be accessed externally from the Fusion Data Foundation cluster.
Annotating encrypted RBD storage classes
This section provides you with information on annotating encrypted RBD storage classes.
Enabling faster client IO or recovery IO during OSD backfill
use this procedure for faster recovery during OSD backfill.
Setting Ceph OSD full thresholds
You can set Ceph Object Storage Daemon (OSD) full thresholds by using the OpenShift Data Foundation command-line interface (CLI) tool or by updating the StorageCluster Custom Resource (CR).
