I've got the same setup and just have to "online" the usb key after boot. As for the zil/log device, I think it should be supported in the upcoming ZFS v28 patch (maybe you can give it a try, see pjd's mail) because zil removal was introduced in a zpool version after v14/15 (what's in 8-STABLE and 9-CURRENT). > > I do not use a log device. > > Bye, > Alexander. > > -- > Govern a great nation as you would cook a small fish.
