Use Online RAID Capacity Expansion and Online RAID Level Migration
Scenario
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 the 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.
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.
