mkdir: can't create directory because of permission denied

[jobcespedes]

Issue

No storage is created when using openebs-hostpath StorageClass.

Actual result

The container init-pvc-<uuid> fails with:

mkdir: can't create directory '/data/pvc-3f7500d7-16ae-11ea-971b-fa163e796691': Permission denied

Expected result

Storage created

Workaround:

1. Permissive selinux in nodes
2. Modify init-pvc-<uuid> and edit: securityContext: {}:

spec:
  securityContext: 
    privileged: true

Environment

Openshift: 4.2
openebsoperator: v1.3.0

Other

I think the issue here is that init-pvc-<uuid> is not running as privileged. Running it as privileged is a better option that a permissive selinux. I just don't know yet which component is to be modified for that to happen.

@jobcespedes , thank you for reporting this issue & apologies for the delay in response. While we shall look into this, would be great if you can add the workarounds into the description of the CSV here: https://github.com/openebs/helm-operator/tree/master/olm/1.3.0 & 1.4.0

This has been fixed in the 1.5 release with this PR: openebs-archive/maya#1542

With this, this step would be sufficient to successfully create the PV with openebs-hostpath storage class:

The OpenEBS 1.5 community operator is now out! @jobcespedes can we close this issue?
