Issue/Introduction

bosh deployment fails when it create disk and throws

 CPI 'create_disk' method responded with error: CmdError{"type":"Unknown","message":"A general system error occurred: Out of resources","ok_to_retry":false}

or it tries to use specific disk but when writing it throws

Status: Cannot complete file creation operation

Resolution

bosh uses CPI calls to your IaaS. In this example it is using vSphere CPI calls to talk to vSphere.
The errors are a result of the CPI calls where vSphere are unable to do the operation successfully and returns an error.

General info with regards to error:

• "A general system error occurred: Out of resources" in vSphere typically indicates insufficient resources (CPU, memory, or storage) to complete a task, often during VM operations like powering on or migrating.
• "Status: Cannot complete file creation operation" is related to not able to write to storage, a similar issue on this KB.

Check with your datastore/vSphere logs or work with your datastore/vSphere admin to investigate this further.
