no, once it is expanded you cannot decrease it's capacity. data integrity will be messed up.
if you don't mind, just leave it in there, upgrade the remaining 3tb drives slowly to larger capacities.
Thanks Bro
So for SHR, to maxmize capacity do I have to use the same or lower size HDD?
So now given that this volume has 5 HDD in 3TBs and 1 HDD in 4TB, to maximize SHR usable capacity I should upgrade to 4TBs. Am I right?
Thanks
