Adding a New Data Store

Question

I have a new Data Store, how do I add it to my cloud?

Answer

The following presumes that you have already configured the hypervisor to see the ISCSI/ATAoE/FC or other block device it is connecting to, including any required multipath configuration. The target disk should be shown when running a fdisk -l.

IMPORTANT: Do this procedure only once per datastore!

Be very careful to choose the disk/partition you wish to use for storing VM data: 

1. Add the new data store to OnApp via the WebUI.
   • Go to  Settings -> Data stores menu
   • Press Add New Data Store button.
   • On the screen that appears indicate the data store details and the data store capacity
2. After creation, check the data store identifier:
   • Go back to the data stores page and read the IDENTIFIER.
3. Login via SSH to the hypervisor, to which you want to add this data store.
4. Create the physical volume (Replace xxx with the real device name):
   • bash#> pvcreate --metadatasize 50M /dev/xxx
5. Create the volume group (Replace xxx with the real device name and IDENTIFIER with the info from the datastore page in the UI):

• df bash#>vgcreate onapp-IDENTIFIER /dev/xxx

6.  Add the datastore to the hypervisor:

• Settings > HV> Click the HV > Settings Tab > manage datastores.

• Choose the datastore and click the add button

Repeat the step 6 for other hypervisors.
