Currently i’m a little bit confused. I’m trying to take care about the correct 4k alignment to get best performance for new HDDs with size > 2TiB. I’m using the following command till now, but i know it is not the optimal setting, but how to tell parted to auto-align the partition?
parted -s — ${device} mklabel gpt mkpart primary 0 -1
Using
parted -s -a optimal — ${device} mklabel gpt mkpart primary 0s -1s
does not fix the problem. Everytime the partition layout looks like
# fdisk -lu /dev/sdd

Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 0, 1) logical=(0, 0, 2)
Partition 1 has different physical/logical endings:
phys=(1023, 254, 63) logical=(13, 0, 51)
which is not optimal. Any tipps?
