Intermittent E2E test failure: DevWorkspace fails to start due to FailedMount on OpenShift CI

[rohanKanojia]

Description

I observed this intermittent E2E test failure on OpenShift CI. Initially I was confused as this failure was unrelated to my pull request changes. When I restarted the workflow, it passed.

The test case [Create DevWorkspace and ensure data is persisted during restarts] [It] Start DevWorkspace failed due to a FailedMount error when attempting to start the DevWorkspace.

Expected Behavior

The E2E test should pass consistently across OpenShift CI runs.

Acceptance Criteria

• Confirm whether this issue is CI/environment-specific or reproducible locally.
• Identify the root cause of the FailedMount test failure and fix it
