CNS PODs fail to start with error " Failed to create: directory = /vmfs/volumes/datastore-xxxx/catalog "

Products

• VMware vCenter Server

Issue/Introduction

 This issue occurs when FCD catalog cannot be created on datastore. 

Cause

This issue occurs when the CNS volumes are migrated/upgraded from Kube volumes to FCD.

When CSI is upgraded, the catalog folder turns out as a hidden folder "<special-charecter>.catalog" which is not visible on the datastore.

Unable to create a folder catalog on the same VMFS path.

Resolution

Try to create a directory for catalog

mkdir /vmfs/volumes/affected-file-path/catalog

In case of failure, please engage the Storage Vendor to further analyze and fix the problem.

If you are able to successfully create the directory, CNS pods be able to start and you should be able to create PVCs.
