The default version is 1.2. When installing anaconda gives the /boot partition the appropriate version when creating the array. You can check the version with mdadm -D . -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
