That's stable on Btrfs so you can just choose that in the Volume->Modify menu, and choose raid0 there (instead of single). This only applies to data. It will still be raid1 metadata. That might seem odd. Don't think of a full drive failure but rather silent corruption on one of the drives - the file system itself will be able to detect that and self-heal without face planting. If a drive fully fails, then you're in this curious situation where you definitely won't be able to boot since half the OS is missing. But you could do a partial recovery of the files on the surviving drive. Most likely this is a big mess but some folks might find it useful. Another way to do this is just select the two drives, and do an automatic installation. And then convert to raid0 after installation and reboot. btrfs balance start -dconvert=raid0 / -- 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
