Page 48: Chapter 4 Raid Modes And Drive Management
Chapter 4 RAID Modes and Drive Management Chapter 4 RAID Modes and Drive Management Available RAID Modes The TeraStation supports multiple types of RAID. The type of RAID arrays available for use depends on how many drives are installed on your TeraStation. Notes: •...
Page 49: Working With Raid Arrays
Chapter 4 RAID Modes and Drive Management RAID 0 A RAID 0 array combines two or more drives into a single array. The usable space is equal to the total capacity of all drives in the array. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data in the array will be lost.
Page 50: Creating A Raid Array
Chapter 4 RAID Modes and Drive Management Click Delete RAID Array. The “Confirm Operation” screen will open. Enter the confirmation number, then click OK. Click OK when finished. Next, create a shared folder by referring to the “Adding a Shared Folder” section in chapter 3.

Chapter 4 RAID Modes and Drive Management Click Options. Click Edit. Change the “Automatically Rebuild if New Drive Is Detected” option to “Yes” and click OK to finish. Configuring Actions for If a Drive Used for the RAID Array Has Not Been Detected You can configure actions to be taken by the TeraStation if a drive used for the RAID array cannot be mounted when booting.
Page 55 Chapter 4 RAID Modes and Drive Management From Settings, click Storage. Click the settings icon ( ) to the right of “RAID”. Click Options. Click Edit. Change the “Drive Detection Window” option to “Don't prompt when a drive could not be detected” and click OK to finish.
Page 56 Chapter 4 RAID Modes and Drive Management If the confirmation screen is not set to appear, an undetected drive will automatically be dismounted from the TeraStation. Subsequently, the TeraStation will enter degraded mode if a redundant RAID mode has been configured and the RAID array will be corrupted if RAID 0 has been configured, resulting in data loss.
Page 57: Configuring A Hot Spare
Chapter 4 RAID Modes and Drive Management Configuring a Hot Spare If you have a hot spare configured and an array fails, the TeraStation immediately switches over to the hot spare. To use a hot spare, you need a RAID 1 or RAID 5 array and an extra drive that’s not part of an array. Notes: •...

Expanding RAID Capacity Without Deleting Data You can create or expand a RAID array without erasing data on the drive by using RMM (RAID Mode Manager).
Page 59 Chapter 4 RAID Modes and Drive Management Insert the new drive (sold separately) into the empty slot with the lock mechanism remaining open and swing the lock back down until it clicks into place. Close the front cover. When the drive is recognized, the status LED will flash red and the message will appear as a notification.
Page 60 Chapter 4 RAID Modes and Drive Management The “Confirm Operation” screen will open. Enter the confirmation number, then click OK to finish. Drives Are Currently in JBOD If the drives are currently in JBOD (not in a RAID array), you may change it to a RAID 1 array. To create the RAID 1 array using RMM, you must have at least two drives available in JBOD.
Page 61 Chapter 4 RAID Modes and Drive Management Set the RAID mode to “RAID 1”. Select the “Add a drive to a RAID array with RMM. Your data will be preserved. ” checkbox. Select the drive whose data will be saved from the drop-down list. Select the drive to add to the RAID array.

Page 64: Adding An External Drive
After a USB drive is recognized, the TeraStation adds “usbdisk x” to the shared folder list, where “x” is the USB port to which the drive is connected. Compatibility Supported file systems for external USB drives are below: File Systems Recommended Situation Btrfs Connecting to this TeraStation. Connecting to another Buffalo NAS device.
Page 65: Dismounting Drives
Chapter 4 RAID Modes and Drive Management File Systems Recommended Situation Connecting to another Buffalo NAS device. XFS is recommended because the Ext3 more files stored in one folder, the slower the performance. The available capacity will be less than the area formatted to XFS.
