Changing Tracefs Partition Size

Zenarmor uses Tracefs which is a thin stackable file system for capturing file system traces in a portable manner, in the directory /usr/local/zenarmor/run/tracefs. If you see warnings in the system log that this partition is full, you will need to increase the disk space size. The minimum and maximum size of the Tracefs disk is 100 MB and 500 MB, respectively.

Tracefs Partition Size pane on the Database page allows you to set the Tracefs disk size used by Zenarmor.
