RAID Management

Remember to update format.nix.

Adding a new drive

Create a format.nix containing the new disk layout. Do not include already existing disks in this file, nor the global pool.

disko -m "destroy" --yes-wipe-all-disks format.nix
disko -m "format" --yes-wipe-all-disks format.nix
btrfs device add /dev/mapper/storage2 /mnt/storage
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/storage --bg

Removing an old drive

sudo btrfs device remove /dev/mapper/storage1 /mnt/storage
btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt/storage
sudo cryptsetup close storage1
