Recently, there was an issue related to the legacy web hosting accounts associated with the lack of disk space on the system partition.
We have identified what was causing it and fixed the issue. The lack of disk space was caused by a system service that was generating gigabytes of logs within minutes.
To avoid something similar from happening again, we implemented a different partition for the logs. We have also taken the opportunity to implement a different partition for the MySQL Databases to prevent similar issues in the future.
The new partitions were implemented with logical volumes. Using logical volumes, we will be able to increase disk space as necessary within minutes.
