- Jeffrey invested four 250GB hard drives for initial setup of TS-509 Pro and configured RAID 5 disk configuration with the four drives.
- A half year later, the data size of the department has largely increased to 1.5 TB. In other words, the storage capacity of TS-509 Pro is running out of use. At the same time, the price of 1TB hard drives has dropped to a large extent.
In 'Disk Management' > 'RAID Management' page, select the drive volume for expansion and click on 'Expand capacity'.
Click 'Change' for the first hard drive to be replaced. Follow the instructions to proceed.
When the description displays 'Please remove this drive', remove the hard drive from the NAS. Wait for the NAS to beep twice after removing the hard drive.
When the description displays 'Please insert the new drive', insert the new drive to the drive slot.
After inserting the hard drive, wait for the NAS to beep. The system starts rebuilding.
After rebuilding finishes, repeat the steps above to replace other hard drive(s).
After changing the hard drives and rebuilding completes, you can click 'Expand capacity' to execute RAID expansion.
Click OK to proceed.
The NAS beeps and starts to expand the capacity.
The process may take from hours to tens of hours to finish depending on the drive size. Please wait patiently for the process to finish. Do NOT turn off the power of NAS.
After RAID expansion is finished, the new capacity is shown and the status is Ready. You can start to use the larger capacity. (In the example you got 3.7TB logical volume)
- During the initial setup of TS-509 Pro, Jeffrey invested a 1TB hard drive and configured it as Single Disk mode. The TS-509 Pro is used as a file server for data sharing among the department.
- After a half year, more and more important data are saved on TS-509 Pro. There is a rising concern for hard drive crash and data loss. Therefore, Jeffrey planned to upgrade the disk configuration to RAID 5.
- Prepare hard drives of the same or larger capacity as an existing drive in the RAID configuration.
- Execute RAID Migration (Migrate the system from Single Disk mode to RAID 5 with 4 hard drives)
Go to 'Disk Management' > 'Volume Management' page. The current disk volume configuration displayed on the page is Single Disk (the capacity is 1TB).
Insert the new hard drives of 1TB capacity to drive slots 2, 3, 4 and 5 of NAS. The NAS system will detect the new hard disks. The status of the new disks is 'Unmounted'.
Go to 'Disk Management' > 'RAID Management' page, select the drive configuration for migration and click on 'Migrate' to proceed.
Select one or more available drives and the migration method. The drive capacity after migration is shown. Click on 'Migrate' button again to proceed.
Note that all the data on the selected drives will be cleared. Click OK to confirm.
When migration is in process, the required time and total drive capacity after migration are shown in the description field.
After migration completes, the new drive configuration is shown (RAID 5 now) and the status is Ready. You can start to use the new drive configuration.
The process may take from hours to tens of hours to finish depending on the drive size. You can connect to the web page of NAS to check the status later.
- Jeffrey had a tight schedule to set up the file server and FTP server. However, he had only one 250GB hard drive. Therefore, he set up the TS-509 Pro with the Single Disk configuration.
- The original plan was to set up a 3TB RAID 5 network data center with TS-509 Pro.
- Jeffrey now planned to migrate the disk configuration of TS-509 Pro to RAID 5 and expand the total storage capacity to 3TB with all the original data retained after the hard drives are purchased.
Execute Online RAID Level Migration to migrate the system from Single Disk to RAID 5. The total storage capacity will be 750GB of RAID 5. (With one 250GB drive and three 1TB drives, the disk usage will be 250GB*4 for RAID 5.) PS: You can refer to the Step 2 for detailed operation procedure.
Execute Online RAID Capacity Expansion, to replace the 250GB drive with a new 1TB drive, and then expand the logical volume from 750GB to 3TB of RAID 5. PS: You can refer to the Step 1 for detailed operation procedure.
