I'm not sure if this is even possible with mdadm or lvm. For sure they have no way of knowing which mirror is correct. But even if it's possible, it's a bit complicated because it implies repartitioning in order to make room for the necessary metadata area. Whereas converting a Btrfs volume from single to raid1 uses balance code, so it isn't any riskier than a full balance. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
