Hi,
Before creating a pool I setup two disks mirror with gnop trick to have ashift=12 - 4k pool alignment. I also did that for the disk partitions (gpt -a 4k option) to have partitions 4k alignment (diskinfo -v disk shows stripesize=4096 for both disks).
Now I replaced one disk with a new one, but cant get the diskinfo or gpart list to display stripesize=4096.
Do you have an idea if that at all is needed? Some other information I found says that as long as pool is 4k alignment is done (ashift=12) you do not need to do 4k alignment for new disk for partitions with gpart -a 4k option.
Many Thanks,
Karolis
