HARD DISK EXPANSION
REMOVING HEALTHY DISKS FROM A RAID VOLUME
Unprotected volumes (Single-disk volume, RAID 0, or JBOD):
Removing the sole disk in a single-disk volume will break the RAID and all data will be lost. Since
NAS OS is installed on the hard drive, you will lose connection to the device if the only disk in the enclosure is
removed while the device is powered on. Try to shut the NAS off then reinsert the disk. Power on the device
and wait approximately five minutes before logging on to the Dashboard.
Removing a healthy hard disk from an unprotected volume while the LaCie 2big NAS is powered
on will break the RAID and all data will be lost. To avoid problems, shut down the LaCie NAS before
removing healthy disks. Return the hard drives to their proper bays before powering on the LaCie NAS.
Powering on the LaCie 2big NAS with a missing disk in an unprotected volume will break its RAID and all data
will be lost.
Protected volumes:
Removing a healthy hard disk from a protected volume while the LaCie 2big NAS Pro is powered
on will render the volume unprotected. You can remove a disk from a protected volume to expand
capacity or replace a failed disk (see
the LaCie NAS before removing healthy disks. Return the hard drives to their proper bays before powering on
the LaCie NAS.
If a healthy disk has been removed while the LaCie 2big NAS is powered on and you do not want to replace it,
you can reinsert it into the enclosure slot. Data remains intact as the volume's hard disks synchronize.
Important info: If a hard disk that you have purchased from LaCie fails, please contact your LaCie reseller
or LaCie Customer Support.
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.
EXPAND THE RAID BY ADDING A SECOND DISK TO THE ENCLOSURE
Select your RAID below to add the new disk to an existing volume.
RAID 0
A RAID 0 volume cannot be expanded with new disks added to the enclosure and/or swapped for disks of higher
capacity. Doing so will break the RAID 0 volume and destroy all of its data. Additionally, data will be lost in a
RAID 0 volume if one of its disks fails. In such a case, you can replace the failed disk and create a new RAID
volume (see New Storage Volume Wizard
