Create the OSDs and Journal Devices using Multi-Create

The Multi-Create tool makes the creation of the Ceph Journals and OSDs very simple, with a single dialog handling the initialization of all components. Use the following instructions to begin.

• Select the Scale-out Storage Configuration tab in the top menu of the QuantaStor WebUI and click the Multi-Create button from the Storage Media section of the ribbon bar.

A dialogue box titled Create Object Storage Daemons/Devices (OSDs) will open:

• Mark the disks intended for use as Journals from each system
• Click the > arrow by the Ceph Journal Disks section to set the disks as Journal devices
  • If Journal devices already exist in the Ceph Cluster the Use available Ceph Journal partitions checkbox can be marked

• Next select the remaining disks to be used as OSDs and click the > arrow to add them to the OSD list
• Once satisfied with the arrangement, press OK to initiate Journal and OSD creation

Once this form is submitted, QuantaStor will begin the process by creating an BlueStore Storage Pool for each of the disks added as an OSD in the Multi-Create dialogue. This process takes time. Allow a few minutes after the final Create Ceph OSD task completes for all OSDs to show up and fully initiate.

Please see the Manual Journal and OSD creation section in Management and Operation below for details on how to manually build the Journals, BlueStore Storage Pools, and OSDs. Because of the number of steps required and complexity, manual creation discouraged in favor of the Multi-Create tool.
