I’m encountering an issue with my Kickstart script when installing AlmaLinux 9 on a disk that previously had an OS installed. After clearing the partition table with dd, the installation fails with the error: Failed to save storage configuration.
Here are the details:
- Failure Scenario: After clearing the partition table, the Kickstart installation fails with
Failed to save storage configurationdue toRequested disk sda doesn't have a usable disklabel for partitioning. - Successful Scenario: Rebooting the system and running the Kickstart script again succeeds. The script works properly on empty disks and in AlmaLinux 8.
I would expect that after clearing the partition table, using the command clearpart --initlabel --drives=$sysdisk --disklabel=gpt would create a GPT label on the specified disk.
