Review the instructions below before adding or replacing hard drives.
A protected volume can be:
Removing a healthy hard disk from a protected volume while the LaCie 5big NAS Pro is powered on will render the volume unprotected. If the volume has double-disk security, removing two healthy hard disks while the LaCie 5big NAS Pro is powered on will render the volume unprotected. While removing healthy disks is not recommended, you can avoid breaking the RAID by shutting down the LaCie NAS first. Return the hard drives to their proper bays before powering on the LaCie NAS.
If a healthy disk has been removed while the LaCie 5big NAS Pro is powered on, you can reinsert it into the enclosure slot and NAS OS will synchronize the RAID. It is important to note that during synchronization:
The instructions below pertain to storage expansion in a LaCie 5big NAS Pro with available or empty drive slots. If you are exchanging an existing hard disk in your enclosure for a hard disk of greater capacity, please follow the instructions in Repair a failed disk or expand storage capacity.
LaCie NAS OS gives you the freedom to configure volumes and RAID for your network. While it is not possible to list every option for expansion, review the examples below and apply them to your situation.
You can use the volume while it synchronizes the data. NAS performance can be affected during synchronization.
The example below shows how to add a new disk to a RAID 5 volume. You can use the same instructions when adding disks to your Custom RAID volume.
You can access data while the volume is resized. The total capacity of the volume will be available once the synchronization is complete.
Follow the instructions below to:
If your volume is protected, you can remove one hard disk from the 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.
When replacing or expanding hard drives in a protected RAID volume:
The SimplyRAID volume in the example below has five disks: four 2TB disks and one 1TB disk.
The time to synchronize the volume depends upon the amount of disks and the total capacity. The Storage page will update the volume capacity following the synchronization.
You can continue to access files stored on your LaCie NAS during the RAID synchronization.
The example below shows two volumes, RAID 5 (three disks) and RAID 0 (two disks). The RAID 5 volume has two 2TB hard disks and one 1TB hard disk. The instructions below demonstrate the expansion of the 1TB hard disk to a 2TB hard disk. You can use the same instructions when swapping an existing hard disk in your custom RAID for a failed or higher capacity disk.
You can access files stored on your LaCie NAS during the RAID synchronization.
If a hard drive in a protected volume fails and you do not have a replacement disk, you can reset the RAID using the New storage volume wizard. Before you reset the RAID, LaCie recommends that you back up your files since all data will be deleted. See Backup Jobs for instructions on backing up your NAS.
To reset the RAID:
