[OmniOS-discuss] mixing 512B and 4K disks in vdev

[Michael Rasmussen]

Hi all,

I have to replace a HDD disk in a mirrored vdev which is using ashift=9.
The problem is that all new HDD's is 4K disks so I wonder if anyone has
made some performance measurements of using a 4K disk with ashift=9 in
contrast to the obvious ashift=12?

As I understand it you cannot detach a vdev from a pool so it is not
possible to replace both disks with 4K disks. How do you handle a
situation like this?
