Preparation
Identify which directories has high I/O rate by the following command.
sudo watch -d -n 1 "find /var -type f -size +80k -mmin -10 -printf '%-30s \t %t %p\n'"
Check the current size of the identified directories.
du -hs /var/log
Take a statistic for the average disk write per minute before the setup.
iostat -h /dev/nvme0n1 -d 60
Install log2ram
echo "deb [signed-by=/usr/share/keyrings/azlux-archive-keyring.gpg] http://packages.azlux.fr/debian/ bullseye main" | sudo tee /etc/apt/sources.list.d/azlux.list
sudo wget -O /usr/share/keyrings/azlux-archive-keyring.gpg https://azlux.fr/repo.gpg
sudo apt update
sudo apt install log2ram
Setup log2ram
sudo nano /etc/log2ram.conf
SIZE=2G
MAIL=true
PATH_DISK="/var/log"
ZL2R=false
COMP_ALG=lz4
LOG_DISK_SIZE=100M
Modify the default systemd timer unit, if you want to log more or less frequently than one time per day.
sudo systemctl edit log2ram-daily.timer
Reboot the system. After the reboot check does it working and use the iostat command to take a new statistic.
