In QuantaStor, the "Create OSDs & Journals" feature serves the purpose of provisioning and managing OSDs (Object Storage Daemons) and their associated journals within a Ceph cluster. OSDs are responsible for storing data in a Ceph storage cluster, while journals facilitate efficient data handling and recovery.

Here are the key purposes and functionalities of the "Create OSDs & Journals" feature:

  • OSD provisioning: The feature allows you to create and provision OSDs within the Ceph cluster. OSDs are responsible for storing data and handling data replication, recovery, and rebalancing operations. By creating OSDs, you can allocate storage capacity to the Ceph cluster and expand its storage resources.
  • Journal configuration: Journals in Ceph serve as a write-ahead log to optimize data handling and ensure data integrity. The "Create OSDs & Journals" feature allows you to configure journals associated with the OSDs. Journals can be created on dedicated storage devices or by using a partition on the OSD drives.
  • OSD and journal placement: When creating OSDs and journals, you can specify the placement of these resources. This includes selecting the storage devices or partitions where the OSDs and journals will reside, ensuring optimal performance and distribution within the Ceph cluster.
  • Storage optimization: QuantaStor provides options for optimizing storage performance, such as caching and tiering. When creating OSDs and journals, you can configure these optimization settings to enhance data access and performance within the Ceph cluster.
  • Fault tolerance and redundancy: By creating multiple OSDs and configuring appropriate data replication settings, you can ensure fault tolerance and data redundancy within the Ceph cluster. The "Create OSDs & Journals" feature allows you to define the replication factor and specify the number of OSD copies for data redundancy.
  • Monitoring and management: Once OSDs and journals are created, QuantaStor provides monitoring and management capabilities for these resources. This includes tracking the status, health, performance metrics, and utilization of OSDs and journals within the Ceph cluster.

By utilizing the "Create OSDs & Journals" feature in QuantaStor, you can provision, configure, and manage the underlying storage resources necessary for data storage and management within a Ceph cluster.

Create single/multiple OSD(s) by selecting from the Available Devices listed and moving them to the desired allocation type list (Data or Journal Devices).

Note: With the Auto Config button one can automatically configure OSD's and Journal Devices.
