xrun_detected , 2 months ago I've recently done this on one of my machines, these were the steps I as far as i remember: backup! add the new disks to the machine partition them like the smaller disks add the new disks to the array(s) (as members, not just spares) take care of bootloader things while the raid is syncing your raid should have 4 devices in sync now fail and remove the smaller disks from the raid one by one resize the partitions on the bigger disks to maximum grow the MD raid to the new size If you use luks and/or lvm some additional steps will be needed to grow them as well. If your system can hotplug disks there's a chance to pull this off with little to no downtime. :)
