System Setup

Hostname

hostnamectl set-hostname --static overlord

Swap file

sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile

sudo swapon /swapfile

Add this line to /etc/fstab

/swapfile none swap defaults 0 0

Swapiness

sysctl -w vm.swappiness=10
echo 'vm.swappiness=10' | sudo tee /etc/sysctl.d/99-swappiness.conf >/dev/null

Make journal persistent

https://doc.opensuse.org/documentation/leap/reference/html/book-reference/cha-journalctl.html

Disable hibernation

sudo systemctl mask hibernate.target hybrid-sleep.target

Faster don't wait so long on shutdown

in /etc/systemd/system.conf and /etc/systemd/user.conf:

DefaultTimeoutStartSec=15s
DefaultTimeoutStopSec=15s

Disable CPU security mitigations

Without grubby

Add mitigations=off to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, then

on Fedora run:

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

on Debian derivatives run:

sudo update-grub

With grubby

sudo grubby --update-kernel=ALL --args="mitigations=off"

Check if it worked

Reboot and run

lscpu

LVM

When creating LVM entities it's good idea to give them discernible names (e.g vg00, lv_data0) so they're easy to spot in output from lvm commands. Naming them just vg, lv, etc. leads to a lot of confusion later.

Create LVM cache

create PV and add it to VG in one command

vgextend MyVolGroup /dev/fastdisk

writethrough is safer in case disk fails, writeback is faster

lvcreate --type cache --cachemode writeback -l 100%FREE -n root_cachepool MyVolGroup/rootvol /dev/fastdisk

Display lvm cache mode

lvs -o+cache_mode MyVolGroup/rootvol

Remove cache

lvconvert --uncache MyVolGroup/rootvol

Hostblock
