Create BTRFS RAID1 inside a single LUKS container - Single password method!

Luks: https://en.wikipedia.org/wiki/Linux_U... Btrfs: https://www.synology.com/en-us/dsm/Btrfs Raid: https://www.prepressure.com/library/t... Sample Xonsh scripts using this method: https://github.com/magnacore/Producti... https://github.com/magnacore/Producti... Commands: RAID 1 inside a LUKS Unmount if needed See which dev we are working with lsblk Create the luks container sudo cryptsetup luksFormat /dev/sdb Open the container sudo cryptsetup luksOpen /dev/sdb luks-laptop-backup-full Optional: sudo wipefs --all --backup /dev/mapper/luks-laptop-backup-full LVM2 PV Create: sudo pvcreate /dev/mapper/luks-laptop-backup-full sudo pvdisplay Create volume group sudo vgcreate vg-laptop-backup-full /dev/mapper/luks-laptop-backup-full Create logical volumes sudo lvcreate -n raid1-1 -l 50%FREE vg-laptop-backup-full [sudo lvcreate -n part_one -L 7g vg-laptop-backup-full (capital L for size)] sudo lvcreate -n raid1-2 -l 100%FREE vg-laptop-backup-full (small l for percentage) go to disks : they will be mounted as (reboot they will go away) /dev/vg-laptop-backup-full/raid1-1 /dev/vg-laptop-backup-full/raid1-2 Create the raid : give the volumes directly, dont format them individually and then try to create a raid: sudo mkfs.btrfs -L laptop_backup_full -d raid1 -m raid1 -f /dev/vg-laptop-backup-full/raid1-1 /dev/vg-laptop-backup-full/raid1-2 mount any one of them using disks. It will appear in /media/manuj/laptop_backup_full OR, create the mount folder, mount it and later delete the mount folder sudo chown manuj:manuj /media/manuj/laptop_backup_full sudo btrfs filesystem show (we will see both disks have same used space even if we copy only one file to one drive. This is because they were mirrored. copy time also doubles) sudo btrfs filesystem du /media/manuj/laptop_backup_full/ (if we duplicate a large file, we will see it in set shared) blkid /dev/sdb btrfs fi df /media/manuj/laptop_backup_full/ Unmount: sudo umount /media/manuj/laptop_backup_full See open volumes sudo lvs -S "lv_active=active && vg_name=vg-laptop-backup-full" Close all open volumes in a group sudo lvchange -an vg-laptop-backup-full If we do a lsblk, we will only see the luks container. No volume group will be there. We have to close the container starting with luks* sudo cryptsetup luksClose luks-laptop-backup-full
