Migrate (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:
Migrate the system from single disk to RAID 1, RAID 5, RAID 6 or RAID 10
Migrate the system from RAID 1 to RAID 5, RAID 6 or RAID 10
Migrate the system from RAID 5 with 3 hard drives to RAID 6
You need to:
Prepare a hard drive of the same or larger capacity as an existing drive in the RAID
configuration.
Execute RAID level migration (migrate the system from single disk mode to RAID 5
with 4 hard drives).
Go to “Storage Manager” > “Volume Management”. The current disk volume configuration
displayed on the page is single disk (the capacity is 250GB).
