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, RAID 5 (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.
Execute 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.
Adding Hard Drives
Follow the steps below to add a hard drive member to a RAID 5 or RAID 6 disk
configuration.
1. Make sure the status of the RAID 5 or RAID 6 configuration is "Ready".
2. Install a hard drive on the NAS. If you have a hard drive which has already been
formatted as single disk volume on the NAS, you can add this hard drive to the RAID
5 or RAID 6 configuration. You are recommended to use hard disk drives of the same
storage capacity for the RAID configuration.
3. Select the RAID 5 or RAID 6 configuration on the "RAID Management" page and click
"Add Hard Drive".
4. Select the new hard drive member. The total drive capacity after adding the drive
will be shown. Click "Add Hard Drive."
5. All the data on the new hard drive member will be deleted during this process. The
data on the original RAID 5 or RAID 6 configuration will be retained. Click "OK". The
NAS will beep twice.
To add hard drives member to a RAID 10 disk volume, repeat the above steps. Note that
you need to add an even number of hard disk drives to a RAID 10 volume. The storage
capacity of the RAID 10 volume will increase upon successful configuration.
This process may take a few hours to tens of hours to complete depending on the
number and the size of the hard drive. Please wait patiently for the process to finish. Do
NOT turn off the NAS during this process. You can use a RAID configuration of larger
capacity after the process.
