[OmniOS-discuss] 4kn or 512e with ashift=12

[Fred Liu]

The ashift parameter doesn't apply in illumos if my memory serves me well. It was introduced by ZoL.

Thanks.

Quick, question.

Any performance differences between 4Kn and 512e with ashift=12?

I am thinking there should not be, since they will both write the full
4K block size.

The workload will be virtual machines using a zvol.

thanks,

Geoff
