Troubleshooting steps

  • Check the free disk space

    • Verify the available space on the drive where MD Core is installed.

  • Check the biggest table size

Resolution

The ometascan-db-vacuum tool requires at least 1.5 times the size of the largest table in free disk space to run successfully.

  • Example: If the largest table is 20GB, ensure at least 30GB of free disk space

This requirement exists because the vacuum process creates a temporary copy of the table during optimization.
