I used to run a raspberry pi4 as my NAS, but now I'm upgrading to an unraid setup. I have 2 new disks installed in the array, plus an SSD cache. But now I want to add the data (and the disk, format is ext4) from my old setup to the array. Once the data is moved, I'll clear the disk and add it to the array in the xfs format.
What is the best way to add the data on this new disk to my array? I read a post about unassigned devices plugin, would that method be bottle-necked by the network? Would it be better to just mount the disks from the console and "cp -r" the contents to the data drive? Looking to copy about 3TB of data, so would really like to avoid a network copy if possible.
Thanks,
Nate
