Description
For storing events for a long time, customer must have large disk space for event storage (eventdb in Accelops VA). There are two ways to do it.
This document explains how to support disks more than 2TB in Accelops VA. But be sure you communicate to customer that, because we stripe all disks together as software RAID 0, any disk fails will cause the full file system unrecoverable crash. Customer has to take their own risk.
Assume:
Goal:
Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot
