Hi all, I've installed a Root on ZFS raidz2 with geli encryption on FreeBSD 11.2 from the installer. I'm new to geli so trying to simulate a disk failure to make sure I can recover. Once I've replaced 3 drives the zpool seems fine but fails to reboot: http://lordcow.org/boot.jpg , specifically: ZFS: i/o error - all block copies unavailable I'm also asked to enter the passphrase for the new disks separately on boot up prior to the 3rd one failing. I'm guessing the bootcode isn't getting copied correctly but not sure where I'm going wrong, this's what I do after failing and zero'ing a drive: gpart create -s gpt ada0 gpart add -b 40 -s 512K -t freebsd-boot -l gptboot0 ada0 gpart add -b 2048 -s 2G -t freebsd-swap -l swap0 ada0 gpart add -s 15623856128 -t freebsd-zfs -l zfs0 ada0 (to match the tables of the other disks) gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 geli init -e AES-XTS -l 256 -s 4096 -b /dev/ada0p3 (Assuming these are the right parameters given what the installer does? Not using a key, just a passphrase. Should master keys on the existing array be backed up? how?) geli attach /dev/ada0p3 zpool replace zroot ada0p3.eli This succesfully resilvers the drive, but again on the 3rd drive it fails to boot. Any help appreciated.
