new hard drives. The status of the new hard drives is "Unmounted".
3. Go to "Storage Manager" > "RAID Management", click "Action" > "Migrate".
4. Select one or more available drives and the migration method. The drive capacity
after migration is shown. Click "Migrate".
5. Note that all the data on the selected hard drive will be cleared. Click "OK" to
confirm.
6. When migration is in process, the required time and total drive capacity after
migration are shown in the description field.
7. The NAS will enter "Read only" mode when migration is in process during 11%–49%
to assure the data of the RAID configuration will be consistent after RAID migration
completes.
8. After migration completes, the new drive configuration (RAID 5) is shown 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 hard drive
size. You can connect to the web page of the NAS to check the status later.

You had a tight schedule to set up a file server and an FTP server. However, you had
only one 250GB hard drive. Therefore, you set up the TS-509 Pro with a single disk
configuration. The original plan was to set up a 3TB RAID 5 network data center with the
TS-509 Pro. You now plan to upgrade the disk configuration of the 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. Using online RAID level migration to migrate the system from
single disk to RAID 5 the total storage capacity will be 750GB (with one 250GB hard drive
and three 1TB hard drives, the disk usage will be 250GB*4 for RAID 5.) You can refer to
the previous step for the operation procedure.
Use online RAID capacity expansion to replace the 250GB hard drive with a new 1TB hard
drive, and then expand the logical volume from 750GB to 3TB of RAID 5. You can refer to
the previous step for the operation procedure.

Follow the steps below to add a hard drive member to a RAID 5 or RAID 6 disk
configuration.
