Reduce Disk Space Usage

Maintaining healthy disk overhead is critical for server stability. While we recommend external monitoring for your LxRoot cluster, the following configuration tweaks and maintenance steps can help reclaim significant storage space.

Set Control Panel API Server Logs to 'Warn'

By default, verbose logging may capture internal trace messages (like read/write locks) that aren't necessary for standard operations. Switching to 'Warn' ensures only errors and critical warnings are logged, significantly slowing the growth of log files.

How to update log level:

1. Select Settings from the left-hand menu.
2. Click Platform and scroll to the Logs section.
3. Select Warn from the dropdown menu and save.

Clear Out Old Logs and Files

System updates and automated backups can leave behind large artifacts. Use the following SSH commands to identify space-saving opportunities:

1. Identify Large Archives or SQL Dumps

Search within web directories for files larger than 100MB:

find /var/www -name "*.zip" -size +100M

find /var/www -name "*.sql" -size +100M

find /var/www -name "*.gz" -size +100M

2. Manage Container Logs

Docker container logs can grow exponentially if not rotated:

find /var/lib/docker/containers -name "*.log*" -size +100M

3. Analyze Database Size

Check the disk footprint of individual MySQL/MariaDB databases:

du -hs /var/local/LxRoot/mysqlcd-data/data/*
