##### SUMMARY
<!-- Explain the problem/feature briefly -->
Adding a primary storage (of type Ceph in this case) fails with the
following error when no hosts have been added yet
```
com.cloud.utils.exception.CloudRuntimeException: Failed to create storage
pool as it is not accessible to hosts.
```
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal
test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
Start with a clean install of the manager, add a Zone,Pod,Cluster then try
adding Primary Storage
<!-- Paste example playbooks or commands between quotes below -->
~~~
# Using cmk
cmk create storagepool name=CEPH-CHI
url="rbd://cloudstack:[CEPH_AUTH]@ceph:6789/cloudstack" zoneid=[ZONE_ID]
provider=DefaultPrimary scope=zone hypervisor=KVM

##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
The storage pool gets created
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->

Looking here:
https://github.com/apache/cloudstack/blob/main/plugins/storage/volume/default/src/main/java/org/apache/cloudstack/storage/datastore/lifecycle/CloudStackPrimaryDataStoreLifeCycleImpl.java#L470
The command returns all hosts that are enabled and up, then connects it to
the shared pool in our case. However, when the list is empty, then `if
(poolHosts.isEmpty()) ` condition gets triggered, failing the creation.
As this connection is done anyway when adding a new host, I don't see why
one couldn't add a new primary storage without having any hosts during
deployment.
**Note:** we are deploying Cloudstack using Ansible, so we're not following
the order provider by the UI wizard.
