So that means illumos can handle 512n and 4kn automatically and properly? Thanks.

Definitely, the ashift parameter has been around on the illumos for a couple of years. thanks, Geoff On 16-03-20 05:21 PM, Fred Liu wrote: The ashift parameter doesn't apply in illumos if my memory serves me well.

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 _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com<mailto:OmniOS-discuss@lists.omniti.com> http://lists.omniti.com/mailman/listinfo/omnios-discuss _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com<mailto:OmniOS-discuss@lists.omniti.com> http://lists.omniti.com/mailman/listinfo/omnios-discuss
