October 31, 2025Oct 31 I've got 1 parity disk and 10 data disks in my system right now. Amongst those 10 data disks, I've got 1 x 2TB disk and 3 x 3TB disks. I've bought a new 18TB disk, as my parity disk is also 18TB. My goal is to replace those 1 x 2TB and 3 x 3TB disks with my new 18TB disk.This is the first time that I'ld like to replace multiple smaller disks by one larger disk. What's the easiest/fastest way to do this? I've searched for information but I've found a lot of different answers so not sure what to do. Thanks in advance for your help.
October 31, 2025Oct 31 Community Expert Solution There's no automatic way to consolidate multiple disks into a larger one, you could replace parity and one of the small data disks first, then move the data from the other small disks there, then do a new config without them and re-sync parity.
November 13, 2025Nov 13 Author Now that I've moved the data from the small disks to the larger disk, I want to put the small disks out of my system. Is this the correct procedure?https://docs.unraid.net/unraid-os/using-unraid-to/manage-storage/array/removing-disks-from-array/#removing-data-disks
