Hi
I recently upgraded from 11.1 to 11.2, and have had lots of problems. I thought that I was getting out of the woods (see this thread https://forums.freebsd.org/threads/upgrade-from-11-1-release-p15-to-11-2-release-failure.67916/), but currently the machine fails to boot.
The PC is triple boot, using fedora 24 to chainboot FreeBSD. FreeBSD is on 2 ZFS mirrored 4Tb disks.
I can boot a live DVD and import/mount the ZFS pool.
Booting from hard disk, I get a load of 'gptzfsboot error 1 lba {10 digit number]' messages then
ZFS: i/o error - all block copies unavailable
ZFS: can't find root dsl_dir
ZFS: can't find root filesystem
gptzfsboot: failed to mount default pool zroot
FreeBSD/x86 boot
Default: zroot
boot:
I see lots of similar issues when I search for solutions. Many involve running 'gpart bootcode', which I have done already.
The best that I've managed was to follow this thread
https://forums.freebsd.org/threads/upgrade-11-2-zfs-i-o-error-all-block-copies-unavailable.67470/
booting to the OK grub prompt on a live DVD and then trying to manually boot
This did start to boot, but I then got a message saying mountroot unable to remount devfs, init not found then a kernel panic.
