Unprotected volumes (Single-disk volume, RAID 0, or JBOD):
Protected volumes:
Select your RAID below to add the new disk to an existing volume.
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 for instructions).
The screenshot above shows a single-disk volume configured for JBOD (for instructions on how to change the name of the volume from the default to JBOD, see Volume Tools). A JBOD volume can be expanded with a new disk added to the LaCie 2big NAS enclosure. Follow the steps below to add a drive to your JBOD volume:
The screenshot above shows a single-disk volume configured for RAID 1 (for instructions on how to change the name of the volume from the default to RAID 1, see Volume Tools). Follow the steps below to add a second drive:
You can use the volume during the RAID syntonization.
Use the directions below to replace a hard disk that is:
You can remove one hard disk from a protected volume while the product is turned on without losing data. This process is referred to as “hot-swapping”. It is highly recommended that hot-swapping be performed when replacing or expanding a hard disk that is part of a protected volume. You can experience problems if you shut down the LaCie 2big NAS to replace a hard drive with an “unclean” hard drive (with data) from another LaCie NAS or a third-party NAS. In such a case, the NAS OS may become confused and remain frozen as it boots.
When replacing or expanding hard drives in a protected RAID volume:
A RAID 0 volume cannot be expanded using disks of higher capacity. Attempting to do so can delete all data on the volume. If one of the disks in a RAID 0 volume fail, all data is lost.
Replace the failed disk and see New Storage Volume Wizard for instructions on creating a new volume.
A JBOD volume cannot be expanded using disks of higher capacity. Attempting to do so can delete all data on the volume. If one of the disks in a JBOD volume fail, all data is lost.
Replace the failed disk and see New Storage Volume Wizard for instructions on how to create a new volume.
Expand or repair a two-disk volume that has been configured for RAID 1.
The example below will demonstrate how to expand the capacity of a RAID 1 volume from two 1TB hard disks to two 3TB disks. If you are expanding the capacity of your hard disks, make certain to follow all three phases of the update: replace one disk; replace the second disk; and optimize storage capacity. You can also follow the directions to repair a failed hard drive.
Phase 1: Replace the first disk
Phase 2: Replace the second disk
Phase 3: Optimize storage capacity
Now that the two drives have been replaced, you can optimize the RAID for the expanded capacity.
You can access files stored on your LaCie NAS during the RAID synchronization.
