[VMC on AWS] Disk Space limits for Folders and Content Libraries

Products

• VMware Cloud on AWS

Issue/Introduction

To provide information regarding the namespace limit for WorkloadDatastore objects.

Symptoms:
When performing operations within their WorkloadDatastore, you may receive disk space errors although the datastore has adequate space available. You may experience the following:

• Error 'Insufficient disk space on datastore'
• Unable to upload files to a Content Library on WorkloadDatastore
• Other Content Library operations are failing

Cause

VMC datastores are provisioned using vSAN technology.
Folders within vSAN are namespaces which are limited to a maximum size of 255GB. 
The root folder of a Content Library is namespace object in vSAN.
For example: If a folder or Content library contains 253GB of ISO files, adding a 3GB ISO file will fail as the namespace limit is exceeded.

Resolution

To workaround this limit, create another folder or content library to within the WorkloadDatastore.
