Some primitive calcs: 5*18T = 90T, not 100T. Maybe you need 6 hdd? > and then merge them into one volume? If your hardware supports 6 hard drives (5*18T + your 2T), you can use lvm for merging 5 of them to one volume, or create raid0 by mdadm. Some risks with plain disk merging - if one of your drives die, entire volume dies. It may be mitigated by use raid5 with 1 additional drive or raid6 with 2 (see https://en.wikipedia.org/wiki/RAIDhttps://en.wikipedia.org/wiki/RAID) -- Stanislav
