Hi. I have a laptop with two disks and I’d like to use them in a RAID-1 configuration but I also want encryption. I ran into a lot of issues trying to used (mdadm) RAID with LUKS and it looks like BTRFS might be a better solution. So far I’ve installed a fresh copy of Manjaro i3 CE on it using the installer with BTRFS on a single disk and just ignored the other disk during installation.
I am brand new to BTRFS so don’t really know what to do. I think I just need to add a partition on the new drive to BTRFS and then change the mode to RAID. Again, not sure exactly how to do this.
This is what my partition schema looks like after the installation:
Found valid GPT with protective MBR; using GPT.
Disk /dev/nvme0n1: 1000215216 sectors, 476.9 GiB
Model: KINGSTON SKC3000S512G
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 7DC7A800-68BE-4BEE-A7AB-84AFF3F9DBF3
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 2048, last usable sector is 1000215182
Partitions will be aligned on 8-sector boundaries
Total free space is 10331 sectors (5.0 MiB)
Number Start (sector) End (sector) Size Code Name
1 4096 618495 300.0 MiB EF00
2 618496 981751961 467.8 GiB 8300 root
3 981751962 1000206899 8.8 GiB 8300
Thanks for your reply. I might have to re-think this one then. If it’s gonna involve a lot of messing around I might as well just install Arch Linux. I really use Manjaro for convenience when I don’t want to spend days installing an OS. LUKS with (mdadm) RAID should work. It’s a shame the Manjaro installer doesn’t currently support encrypted RAID. Thanks anyway.
