I wanted to move my home server from to 2-way mirror to 3-way raidz. I did it using https://unix4lyfe.org/zpool/ The difference from that tutorial is that I have only 3 HDD's and I use ZFS on root. I've correctly moved to 3-way raidz, but it seems like I can't boot anymore (I've checked that the data is still in the pool). Of course, I did it from LiveCD. The loader is there, but I'm getting a message that it couldn't find /boot/zfsloader, and then that /boot/kernel/kernel was not found. Which is strange, because those files actually are in /boot. Another strange thing is that I use GPT. To be sure, I've reinstalled bootcode using gpart(8) on all 3 disks (with gptzfsboot), but it got me nowhere. I'm right now using the fresh 10.2-RELEASE on amd64.
