Hello, I now have two ssd of around 450Gb each on my PC. I have a root (/) of 100Gb - it's /dev/sda2 I would like to secure this root with an other 100Gb partition in /dev/sdb2 I'm unsure of the best way to do so :-( * make a btrfs raid 1. ** is it possible to make a btrfs add from a running root, or do I need to boot on some recovery system? ** once done will it be possible to boot (from uefi) to any partition (sda2 or sdb2)? in case sda2 fails, do the system boot? from here: https://btrfs.wiki.kernel.org/index.php/Incremental_Backup#Doing_it_by_hand.... I don't understand how to recover the backup in case of failure of the main system :-( thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org
