The main problem is that drive failures can occur when a system crashes, like a sudden power loss. In such a case all other raid 1 arrays would be able to boot normally and continue to be available with one failed drive. Given this honestly bizarre behavior of btrfs in the face of drive failure, I don't think its raid implementation can be considered production ready yet. I understand that raid setups are not the common case, but if it is an option in the installer I think it should at least come with a warning. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx
