This section discusses partitioning and purging related to new data directories. PartitioningNew data directories are used when the next partition occurs (every 3 days by default), or sooner if the current data disk is at risk of becoming full. Active and Read-Only DirectoriesAny cbevents directories prefixed with cbevents* are used to create new cbevent partitions. Any cbevents directories prefixed with _cbevents* are used as read-only. Partition PurgingThe system purges partitions based on disk space, time, or the maximum number of allowed partitions. Extending Disk Space on the FlyYou can add disk space on the fly without having to restart the Carbon Black EDR server. Parent topic: Supporting Multiple Volumes for Event Data
