You overmixed them ;)

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

(lowercase 'i' and pmbr, 1-sector pre-loader for -b)

Dmitry:

I should have read UPDATING AGAIN before even posting my problem and doing things from memory ;-)

But after from a current 10-stable ISO.

gpart bootcode -p /boot/gptzfsboot -i 1 ad0
gpart bootcode -p /boot/gptzfsboot -i 1 ad1

Still yields my original issue



Loading Operating System....
ZFS:  i/o error - all block copies unavailable
ZFS: can't read object set for dataset u
ZFS: can't open root filesystem
gptzfsboot: failed to mount default pool zroot
FreeBSD/x86 boot
Default: zroot:
boot:
boot: status
pool: zroot
boofs: zroot/ROOT/defualt
config:
        NAME STATE
        zroot ONLINE
          mirror ONLINE
            gtpid/E17....... ONLINE
            gtpid/e26...... ONLINE
FreeBSD/x86 boot
Default: zroot:
boot


+++++++++++++++++++++++++++++++++

An added fact that I should have stated but did not think would cause an issue.

When the reboot failed I pulled an additional mirror TANK and cabled up my
SATA DVD-RW to boot and re-install the boot loader as I did not have a USB
stick to boot from.

Since efforts so far have not corrected my issued I reconnect all SATA devices
Remove the DVD-ROM and added back the mirrored tank pool all I assure you
to the same SATA ports.

Interestingly on boot I get the same error I described originally but running
status at the boot prompt causes a BTX error - image attached.

I don't know one has noticed ada2 is a SSD which I have for ZIL/L2ARC could
that cause a problem?

I am perplexed why when I boot a head or 10stable ISO and am in single user
mode that the OS does not find any ZFS partitions.

I can apply patches, build ISO's on another machines to help troubleshoot
but this issue seems to be prevalent and random for a long time since 8.x

boot: status with the non-root mirror tank attached
