With Snare Central using LVM for its file systems, it allows users to easily resize any of them if enough free disk space is available. One thing to notice is that the Snare Central main data storage is the rest of the server's disk capacity. If a new physical disk is added to the system, it can fully or partially be assigned to this file system within the Disk Manager.
