Hard Disk Expansion: Single-Disk and Unprotected Volumes

Review the information below before attempting to add hard disks to a single-disk or unprotected volume.

Important info on NAS Backup: It is recommended that all users back up data to DAS or another NAS as further protection against disk failure or secondary points of failure (e.g. hardware, network, etc.). See Backup Jobs for details.

Removing Healthy Disks from an Unprotected Volume

An unprotected volume can be:

SimplyRAID single-disk
RAID 1 single-disk
JBOD
RAID 0

Removing a healthy hard disk from an unprotected volume while the LaCie 5big NAS Pro is powered on will delete all of the volume's data. While removing healthy disks is not recommended, you can avoid losing data by shutting down the LaCie NAS first. Return the hard drives to their proper bays before powering on the LaCie NAS.

Additionally, powering on the LaCie 5big NAS Pro with a missing disk in an unprotected volume will break its RAID and all data will be lost.
