That's the problem. First use df or mount to see if this device has a mounted filesystem, and if so unmount it. Then you need to close it. cryptsetup luksClose luks-ab8911f9-b3a4-4f33-8b10-7e52c7217ae9 Now you can wipefs the md127 device, then stop the array, then wipe the members of the array. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
