September 23, 20223 yr I have an unraid server with 12 drives on main array. 7 of them are 18TB (1 of the 7 is a parity drive). The remaining 5 drives are smaller. I'd like to replace the 5 smaller drives with 18TB drives. I can change drives one by one and rebuild but is there a faster and less drive torturous way to do it without losing my data? For instance, can I pull all five drives at once, add the 5 replacements, then manually add back the data from the smaller drives I pulled? (e.g. using USB dock or temporary using spare SATA).
September 23, 20223 yr You should mount those new disk i.e. UD then copy in disk-to-disk in same time, after all complete, then new config the array with new disk and rebuild parity. Edited September 23, 20223 yr by Vr2Io

(e.g. using USB dock or temporary using spare SATA). You can also go this way by using the New Config tool to set the drive set you want to keep (although you would then have to rebuild parity to match the new drive set). After doing this you can then mount the old drives in UD to copy the content of the old drives to the array with the new drives in it.
