Use Online RAID C apacity Expansion and Online RAID Leve l Migration
Sce na r io
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 centre 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.
