3. After plugging in the hard drive, wait for the NAS to beep. The system will start
rebuilding.
4. After rebuilding has completed, repeat the steps above to replace other hard drives.
5. After changing the hard drives and disk rebuilding has completed, click "Expand
Capacity" to execute RAID capacity expansion.
6. Click "OK" to proceed.
7. The NAS beeps and starts to expand the capacity.
Tip: After replacing the hard drive, the description field shows "You can replace this
drive". This means you can replace the hard drive to a larger one or skip this step if
the hard drives have been replaced already.
Caution: When the hard drive synchronization is in process, do NOT turn off the
NAS or plug in or unplug the hard disk drives.
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 the NAS.
After RAID capacity expansion has finished, the new capacity is shown and the status is
"Ready". You can start to use the NAS. (In the example you have 1.8TB logical volume.)
Tip: If the description still shows "You can replace this hard drive" and the status of
the drive volume says "Ready", it means the RAID volume is still expandable.
Online RAID Level Migration
During the initial setup of the TS-509 Pro, you bought a 250GB hard drive and configured
it as single disk. The TS-509 Pro is used as a file server for data sharing among the
departments. After a half year, more and more important data are saved on the TS-509
Pro. There is a rising concern for hard drive damage and data loss. Therefore, you
planned to upgrade the disk configuration to RAID 5. You can install one hard drive for
setting up the TS-509 Pro and upgrade the RAID level of the NAS with online RAID level
migration in the future. The migration process can be done without turning off the NAS.
All the data will be retained.
You can do the following with online RAID level migration:
