A failed PostThaw script alert typically indicates incorrect script ownership or permissions, and manually executing the scripts confirms whether they function correctly outside of the NGT context.
Question
An administrator is tasked with protection of a business critical application. The application is running on a Linux VM and is using a custom DB that require application consistent snapshots for data integrity. An administrator has written a pre_freeze and post_thaw scripts and placed them under /usr/local/sbin/. During protection domain scheduled run an alert is generated:
Execution of the PostThaw Script Failed Which two resolution steps could an administrator conduct to fix the issue? (Choose two.)
Options
- AEnsure that scripts have nutanix user ownership and admin access.
- BReview the NGT logs under /usr/local/sbin/post_thaw.
- CEnsure NGT service is up and running.
- DExecute scripts manually and ensure they succeed

Why each option
A failed PostThaw script alert typically indicates incorrect script ownership or permissions, and manually executing the scripts confirms whether they function correctly outside of the NGT context.
NGT executes pre-freeze and post-thaw scripts as the nutanix user; if the scripts do not have nutanix user ownership and the correct execute permissions, NGT will be unable to run them, causing the PostThaw failure alert.
NGT logs are stored in the NGT-specific log directory, not under /usr/local/sbin/; looking for logs in the script directory would yield no results.
NGT must be running for snapshot coordination, but a running NGT service would not resolve a PostThaw script failure caused by incorrect permissions or script errors.
Manually executing the scripts verifies that the script logic itself succeeds and has no internal errors, isolating whether the issue is with script content or with NGT's ability to invoke the script.
