I have what I think is a pretty normal setup.. a bunch of HDDs plus 2 SSDs (one ZIL, one SLOG). The HDDs are standard 512 byte sector drives. The SSDs have 8k page sizes. In Illumos I added the SSDs to sd.conf and created the zpool and it shows the HDDs as ashift 9 and the SSDs as ashift 13, like normal: # zdb -C | grep ashift ashift: 9 ashift: 9 ashift: 9 ashift: 9 ashift: 13 The question is, how to replicate this in FreeBSD? The old "gnop" method doesn't work anymore, and setting "vfs.zfs.min_auto_ashift=13" causes it to use 13 for the HDDs, which seems like a waste. Is this not supported? Thanks! -Dustin
