Noob starting first server. Installed Ubuntu server, and opted for LVM. However, will that cause me problems on a headless server if I get a power outage and need to reboot? I think yes. Is there a solution, or should i remove LVM before i go too deep setting things up?
Maybe I’m missing something obvious, but what is the problem that you anticipate with LVM after a power failure?
Password prompt on boot load. No monitor and keyboard plugged in, and im assuming i cant SSH until LVM password is entered.
Ah, you’re talking about LUKS. LVM is just the volume manager.
The standard way is to add an
sshd(such as dropbear) to yourinitramfsso that you can ssh in and run commands (such as entering the root partition password) during system boot.See:
https://unix.stackexchange.com/questions/5017/ssh-to-decrypt-encrypted-lvm-during-headless-server-boot
servers for data centers often come with IPMI, which allows to remotely operate the server before boot.
you could also have only a data partition encrypted, so it boots the unencrypted OS and you have to SSH in and mount the data partition, entering your password.
