ReadyNAS 2100 User Manual We can also remove a disk from the volume by clicking Remove. The volume will still be available but in a non-redundant state. An additional disk failure would render this volume unusable. Note: The Remove operation is a maintenance feature. NETGEAR recommends that you do not use it in a live environment. Its function is equivalent to hot-removing the disk or simulating a disk failure. The Locate option is a way to verify that a disk is correctly situated in the expected disk slot. Clicking Locate causes disk LED to blink for 15 seconds. Volume Management for X-RAID2 Most people want to either add redundancy or expand their data volume. X-RAID2 enables this without the headaches usually associated with doing so. Adding a Second Disk for Redundancy A one-disk X-RAID2 device has no redundancy and provides no protection from a disk failure. However, if and when you feel the need for redundancy, simply add a new disk with at least the capacity of the first disk. Depending on the size of the disk, within a few hours, your data volume will be fully redundant. The process occurs in the background, so access to the ReadyNAS 2100 is not interrupted. Adding More Disks At a certain point, you will want more capacity. With typical RAID volumes, you have to back up your data to another system (with enough space), add a new disk, reformat your RAID volume, and restore your data back to the new RAID volume. Not so with X-RAID2. Simply add the third disk using the ReadyNAS hot-swap trays. If you are adding multiple disks at the same time, or if your ReadyNAS is not hot-swap capable, power down the ReadyNAS, add the disk(s), and power back on. The X-RAID2 device initializes and scans the newly added disk(s) for bad sectors in the background. You can continue working normally without any lag in performance. When the process finishes, you will be alerted by e-mail to reboot the device. During the boot process, your data volume will be expanded. This process typically takes about 15 to 30 minutes per disk to several hours or longer, depending on the size of your disks, or the quantity of data on your volume. A 250 GB disk takes approximately 30 minutes. Access to the ReadyNAS is not permitted during this time. You will be notified by e-mail when the process is complete. 2-20 Setting Up and Managing Your ReadyNAS 2100 v1.0, May 2009

Volume Management for X-RAID2
Most people want to either add redundancy or expand their data volume. X-RAID2 enables this
without the headaches usually associated with doing so.
Adding a Second Disk for Redundancy
A one-disk X-RAID2 device has no redundancy and provides no protection from a disk failure.
However, if and when you feel the need for redundancy, simply add a new disk with at least the
capacity of the first disk. Depending on the size of the disk, within a few hours, your data volume
will be fully redundant. The process occurs in the background, so access to the ReadyNAS 2100 is
not interrupted.
Adding More Disks
At a certain point, you will want more capacity. With typical RAID volumes, you have to back up
your data to another system (with enough space), add a new disk, reformat your RAID volume,
and restore your data back to the new RAID volume.
Not so with X-RAID2. Simply add the third disk using the ReadyNAS hot-swap trays. If you are
adding multiple disks at the same time, or if your ReadyNAS is not hot-swap capable, power down
the ReadyNAS, add the disk(s), and power back on. The X-RAID2 device initializes and scans the
newly added disk(s) for bad sectors in the background. You can continue working normally
without any lag in performance. When the process finishes, you will be alerted by e-mail to reboot
the device.
During the boot process, your data volume will be expanded. This process typically takes about 15
to 30 minutes per disk to several hours or longer, depending on the size of your disks, or the
quantity of data on your volume. A 250 GB disk takes approximately 30 minutes. Access to the
ReadyNAS is not permitted during this time. You will be notified by e-mail when the process is
complete.
Note:
The Remove operation is a maintenance feature. NETGEAR recommends that you
do not use it in a live environment. Its function is equivalent to hot-removing the
disk or simulating a disk failure.
