To use zram:

### Redundant VM storage
Make encrypted partition `/dev/nvme1n1p1` as `cryptdata1` and `/dev/nvme2n1p1` as `cryptdata2`. If the same passphrase as `/dev/nvme0n1p1` is used for encryption, all 3 drives will be unlocked with just 1 prompt during boot.
To get the filesystem UUID of `cryptdata1` and `cryptdata2`, run
```bash
lsblk -o NAME,UUID
```
Add the following to `/etc/cryttab`:
```
cryptdata1 UUID=PUT_THE_CORRESPONDING_UUID_HERE
cryptdata2 UUID=PUT_THE_CORRESPONDING_UUID_HERE
```
Update the initramfs:
```bash
sudo dracut --regenerate-all --force
```
Make the new RAID 1 BTRFS filesystem:
```bash
sudo mkfs.btrfs --csum blake2b -m raid 1 -d /dev/mapper/cryptdata1 /dev/mapper/cryptdata2
```
**Take note of the UUID**.
Run:
```bash
sudo mkdir -p /var/lib/qubes2
sudo mount /dev/disk/by-id/PUT_THE_CORRESPONDING_UUID_HERE /var/lib/qubes2
sudo btrfs subvolume create /var/lib/qubes2/data
sudo umount /var/lib/qubes2/
```
Add the following to /etc/fstab:
```
UUID=PUT_THE_CORRESPONDING_UUID_HERE /var/lib/qubes2
```
