Symptoms

The Resource Group's Deployment State is in Error, meaning the Resource Group Deployment (Add Existing or Deploy New) failed.
error: a datastore in the Resource Group that is not part of the vCenter / datacenter

 

The error below indicates a datastore in the Resource Group that is not part of the vCenter/datacenter.

To validate the issue, enter the thin-deployer pod, and look into the rackserver-<servicetag_123> log in the <device_name> directory:

  1. Enter the thin-deployer pod:

    x=$(kubectl get pods -n powerflex|grep -i thin|awk '{print $1}'); kubectl exec -it -n powerflex $x -- bash

  2. Enter the <device_name> directory:

    cd /opt/Dell/ASM/device/<device_name>

  3. Look into the rackserver-<servicetag_123> log - indicates that the datastore was not found:

    Error: datastore object powerflex-TESTCLUSTER1-ds-2 not found
Error: /Stage[main]/Asm::Resource_wrapper/Vc_vcls_datastore[TESTCLUSTER1]/ensure: change from 'absent' to 'present' failed: datastore object powerflex-TESTCLUSTER1-ds-2
      not found

     

 

The datastore may still show in the vCenter inventory file - inventory/rs-vc.boston.ee.com.json:

  {"name"=>"powerflex-TESTCLUSTER1-ds-2",
             "id"=>"datastore-120788",
             "type"=>"Datastore",
             "attributes"=>{"is_local"=>false, "free_space"=>12297699328, "mount_dir"=>"/vmfs/volumes/62e1db72-18264b5c-a653-b8599fc367db", 
"volume_name"=>"powerflex-TESTCLUSTER1-ds-2", "capacity"=>15.75, "scsi_device_id"=>"eui.0be0ca503685ed0fea3112de00000004", "vendor"=>"EMC"},
             "children"=>[],
             "path"=>""},

 

Impact

Unable to add Existing Resource Group/Service.

Cause

A limitation in PFxM results in the inability to view vCLS datastores that are within a vCenter folder.
The issue arises because PFxM cannot recursively search through folders in vCenter.

 

Resolution

From the vSphere datastores view, move vCLS datastore(s) that are associated with the Resource Group out of the folder and into the data center:
