Workaround:

1. Review Files for Cleanup:

   • Run the following command to see a list of files that can be safely deleted:

     request system storage cleanup dry-run
     

   • This command simulates the cleanup process and displays the files it would remove. Important: Before proceeding, carefully review the list to ensure no critical files are included.

2. Clean Up Storage (Optional):

   • the files listed for deletion, run the following command to perform the actual cleanup:

     request system storage cleanup
     

   Caution: This command permanently deletes the listed files.

3. Disable Unnecessary Monitoring (Optional):

   • Before running the cleanup, it's recommended to disable traceoptions and rtsockmon if they're enabled on your device. These features can generate log files that contribute to storage usage. Note: Consult your Juniper documentation for specific instructions on disabling these features.
