I did have a quick look over the weekend at your issue and it looks to me like warning for the cache is a false positive, as the vdev for cache doesn't report an ashift in zdb so could well be falling back to a default value. I couldn't reproduce the issue for log here, it just seems to work for me, can you confirm what ashift is reported for your devices using: zdb Regards Steve ----- Original Message ----- From: "Borja Marcos" < --- Дмитрий Макаров
