Issue/Introduction

When adding a host to a cluster in SDDC Manager, the task fails with the following error

 

"No unassigned hosts available with storage type NFS. Commission hosts with physical NICs 0 & 1 to Add Host."

 

Review of the vcf-commonsvcs.log shows cluster deletion and recreation events with an incorrect storage type:

/var/log/vmware/vcf/commonsvcs/vcf-commonsvcs.log: 

YYYY-MM-DD THH:MM:SS.621 [DomainExtensionsImpl] DELETE Domain Inventory JSON { ... "clusters":[ { "name":"dc-p-lx", ... "primaryDatastoreType":"NFS", "id":"58b63cab-####-####-####-############..." } ... ] }
YYYY-MM-DD THH:MM:SS.655 [ClusterInventoryServiceImpl] Delete Cluster - 58b63cab-####-####-####-############
YYYY-MM-DD THH:MM:SS.672 [ClusterInventoryServiceImpl] Create Cluster - 58b63cab- ####-####-####-############ on vCenter - #######-...

 

Environment

VMware Cloud Foundation 9.0.x.  

Cause

The SDDC Manager inventory contains stale primaryDatastoreType metadata. This occurs when a domain sync operation is performed while an NFS datastore is mounted. In VCF 9.0.x, the storage type is not recomputed when a datastore is removed out-of-band in vCenter; it is only rewritten during a full domain sync or import.

Resolution

To resolve this in VCF 9.0.x, re-synchronize the domain inventory:

1. Unmount and detach the NFS datastore from all hosts in the cluster.
2. Confirm the intended FC/VMFS datastore is mounted and accessible.
3. Log into SDDC Manager.
4. Navigate to Inventory > Workload Domains.
5. Select the affected domain and click Actions > Sync Inventory.
6. Verify the storage type updates to FC in the cluster details.
7. Retry the Add Host operation.
