ReadyNAS OS 6.4 To vertically expand a Flex-RAID volume: 1. Replace one disk in the volume with a larger-capacity disk. For more information about how to add a disk to your system, see the hardware manual for your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6. Note You must use supported disks in your ReadyNAS system. For a list of supported disks, visit http://www.netgear.com/readynas-hcl. 2. Wait for the volume to resync your data. You can continue to use your ReadyNAS system while the volume is resyncing. Resyncing can take several hours. The start and completion of the resyncing process are recorded in the system log (see System Logs on page 185). If you set up email notifications for your system, you receive an email message when the process finishes. For more information about alert notifications, see Configure System Alerts on page 153. 3. Repeat Step 1 on page 37 and Step 2 on page 37 until you replace each disk in the volume with a larger-capacity disk. Add Protection to a Volume You can set up protection against disk failure. The types of protection available depend on the number of hard disks installed in the ReadyNAS system. Add Protection to an X-RAID Volume X-RAID requires a minimum of two hard disks to provide protection against disk failure. To add protection from disk failure to a one-disk ReadyNAS storage system, you must add a second disk that is at least as large as the first. You can add it while the system is running. For more information about how to add a disk to your system, see the hardware manual for your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6. An X-RAID volume that includes two or more disks is automatically formatted to protect against the failure of one disk. If you want to protect your data against the failure of two disks, you must switch to Flex-RAID and select RAID 6. To use RAID 6, you must install four or more disks. For more information about how to switch to Flex-RAID, see Change from X-RAID to Flex-RAID on page 25. Add Protection to a Flex-RAID Volume In certain cases, you can add a disk to a Flex-RAID volume to increase data protection. The following table indicates whether adding a disk for data protection is possible for each Flex-RAID configuration. Table 3. Flex-RAID levels and data protection Number of Disks per Volume RAID Level 1 2 2 or more RAID 1 RAID 1 RAID 0 Can I add a disk to for data protection? Yes. (Additional disk provides redundancy.) No. (Volume protection is already redundant.) No. (RAID 0 does not offer protection.) Volume Configuration 37
