Use Online RAID C apacity Expansion and Online RAID Lev el Migration
Sce na r io
You had a tight schedule to set up the file server and FTP server. However, you had only one 250GB
HDD. 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 TS-509 Pro.
You now planned to upgrade the disk configuration of TS-509 Pro to RAID 5 and expand the total
storage capacity to 3TB with all the original data retained after the HDD 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 HDD and three 1TB HDD, 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 HDD with a new 1TB HDD, and then
expand the logical volume from 750GB to 3TB of RAID 5. You can refer to the previous step for the
operation procedure.
