2장. Storage classes

Procedure

1. Click Storage StorageClasses.
2. Click Create Storage Class.
3. Enter the storage class Name and Description.

4. Reclaim Policy is set to Delete as the default option. Use this setting.

   If you change the reclaim policy to Retain in the storage class, the persistent volume (PV) remains in Released state even after deleting the persistent volume claim (PVC).

5. Volume binding mode is set to WaitForConsumer as the default option.

   If you choose the Immediate option, then the PV gets created immediately when creating the PVC.

6. Select RBD or CephFS Provisioner as the plugin for provisioning the persistent volumes.
7. Choose a Storage system for your workloads.

8. Select an existing Storage Pool from the list or create a new pool.

   참고

   The 2-way replication data protection policy is only supported for the non-default RBD pool. 2-way replication can be used by creating an additional pool. To know about Data Availability and Integrity considerations for replica 2 pools, see Knowledgebase Customer Solution Article.

   Create new pool

   1. Click Create New Pool.
   2. Enter Pool name.
   3. Choose 2-way-Replication or 3-way-Replication as the Data Protection Policy.

   4. Select Enable compression if you need to compress the data.

      Enabling compression can impact application performance and might prove ineffective when data to be written is already compressed or encrypted. Data written before enabling compression will not be compressed.

   5. Click Create to create the new storage pool.
   6. Click Finish after the pool is created.

9. Optional: Select Enable Encryption checkbox.
10. Click Create to create the storage class.
