Ubuntu 22.10 - scenarios to configure LVM for encrypted root partition with cryptsetup
I'm integrating two systems and I'm confused about Hey everyone, I'm running into an issue that's driving me crazy... I'm sure I'm missing something obvious here, but I've been banging my head against this for hours. I'm trying to set up a new Ubuntu 22.10 server with an encrypted root partition using LVM and cryptsetup. I followed the installation guide, but I ran into an scenario when I tried to activate the LVM after the installation. I used the following commands to set up my partitions: ```bash # Creating the encrypted partition sudo cryptsetup luksFormat /dev/sda2 # Opening the encrypted partition sudo cryptsetup luksOpen /dev/sda2 cryptroot # Creating the physical volume sudo pvcreate /dev/mapper/cryptroot # Creating the volume group sudo vgcreate vg_root /dev/mapper/cryptroot # Creating the logical volume sudo lvcreate -L 20G -n lv_root vg_root ``` After installing Ubuntu, I modified the `/etc/crypttab` file to include my encrypted partition: ```plaintext cryptroot /dev/sda2 none luks ``` However, during boot, I receive the behavior: **"No root file system is defined"**. I've checked the `/etc/fstab` file and it seems to be set correctly: ```plaintext /dev/mapper/vg_root-lv_root / ext4 defaults 0 1 ``` I also tried running `sudo update-initramfs -u` after making these changes, but the scenario continues. I've double-checked that the logical volume is indeed created, yet I need to seem to get past this boot behavior. Any advice on what I might be missing or additional steps I should take? I'm working on a application that needs to handle this. What am I doing wrong? What's the best practice here? The stack includes Bash and several other technologies. I appreciate any insights! This is my first time working with Bash 3.10. Cheers for any assistance!
