then if it were me, I would opt for btrfs built-in software RAID 1 over mdadm RAID 1+btrfs.
I think it's time to give up, after repairing the mdadm raid, btrfs check segfaults trying to repair the volume. luckily I have a backup... How would you proceed, to create a new setup with btrfs with built-in software RAID 1. I would like to clone the subvolume layout.
first idea is to do a clean new Install (does Yast setup let me set up this btrfs RAID?) - start a rescue system, restore the backup to the new install, clean up /etc/fstab, chroot, dracut, reinstall bootloader.
or is there a faster way (i don't know how to clone the btrfs layout and set up btrfs raid manually) instead of a fresh install. Any literature?
thanks a lot
I recently wrote up how to clone the root sub-volume structure here: https://forums.opensuse.org/showthread.php/521277-LEAP-42-2-btrfs-root-files... But I have no experience with brtrs RAID, so I cannot help there. I suspect it may be easier to completely reinstall a minimum install and then restore over the top of it. But I guess this may result in other problems. You should probably practice in a virtualbox. I don't think the available btrfs docs and google-results have sufficient details to be safe without practising before hand. If you follow the link provided, you will also see that I gave up on btrfs and returned to ext4 because, like yourself, I have recovery processes and procedures that would need quite a bit of rethinking for btrfs.
