4.2.2 RAID Management
You can perform online RAID capacity expansion (RAID 1, 5, 6, 10) and online RAID level
migration (single disk, RAID 1, 5, 10), add a hard drive member to a RAID 5, 6, or 10
configuration, configure a spare hard drive (RAID 5, 6, 10) with the data retained, enable
Bitmap, recover a RAID configuration, and set a global spare on this page.
To expand the storage capacity of a RAID 10 volume, you can perform online RAID
capacity expansion or add an even number of hard disk drives to the volume.
Note: Online RAID capacity expansion, online RAID level migration, and RAID recovery
are not supported by one-bay NAS models, TS-210, and TS-212.
Expanding Capacity (O nline RAID Capacity Expansion)
Scenario
You bought three 250GB hard drives for initial setup of a TS-509 Pro NAS and configured
RAID 5 disk configuration with the three hard drives.
A half year later, the data size of the department has largely increased to 1.5TB. In
other words, the storage capacity of the NAS is running out of use. At the same time,
the price of 1TB hard drives has dropped to a large extent.
Operation procedure
In "Storage Manager" > "RAID Management", select the disk volume for expansion and
click "Action" > "Expand Capacity".
Click "Change" for the first hard drive to be replaced. Follow the instructions to proceed.
1. 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.
2. When the description displays "Please insert the new drive", plug in the new hard
drive to the drive slot.
