This came up in a Google search: https://github.com/jonathanunderwood/mdraid-safe-timeouts It´s for MD arrays, but I´m guessing it could be adapted for BTRFS as well. poc PS One thing that slightly confused me in setting up the RAID array is that, unlike with MD, there´s no new pseudo-device, and you mount the array by just mounting one of its components, right? (I´ve already done it and it works, just checking if I´ve missed something). _______________________________________________ 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 Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
