Running Ceph services

The IBM Storage Ceph dashboard allows you to start, stop, restart, and redeploy daemons.

Before you begin

Before you begin, make sure that you have the following prerequisites in place:
  • A running IBM Storage Ceph cluster.
  • The dashboard is installed.
  • At least one daemon is configured in the storage cluster.

About this task

Note: In the Ceph Dashboard, Ceph daemon processes are managed as services. While the UI and this documentation may refer to daemons to reflect underlying Ceph components, all management actions in the dashboard are performed at the service level

About this task

Note: Daemon actions are supported on all daemons except monitor and manager daemons.
Managing daemons can be done in the following ways:

Managing daemons from Services
