I have a strange bootup issue on a test box that I just updated from
11, to 12 and now RELENG13.
Its a simple mirror. But if I boot up with ada0, I get an error and
cannot boot further. Where as if I boot up with ada1, I get some
errors and then proceeds to boot normally.
For one thing, I dont get where zbackup1 is coming from. The pool I
boot from is zroot ?!? Where would that reference be stored ? I think
ada0 was part of another pool long ago (zbackup1).
OK problem solved. Reboot works on either drive and no errors or
warnings at the start.
# dd if=/dev/zero of=/dev/ada0p1 bs=1 status=progress
# gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
and zdb looks good.
# zdb -l /dev/ada0

Whats odd is that zbackup1 is not the name of the pool. Where is that

It looks like if I do just a
0(nanobsd2)# zpool import
pool: zbackup1
id: 5819795054093255811
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY
config:
zbackup1 UNAVAIL insufficient replicas
raidz2-2 UNAVAIL insufficient replicas
da5 UNAVAIL cannot open
mfisyspd8 UNAVAIL cannot open
mfisyspd7 UNAVAIL cannot open
mfisyspd6 UNAVAIL cannot open
ada0 UNAVAIL cannot open
17460231907795801757 UNAVAIL cannot open
0(nanobsd2)#
it thinks ada0 is/was part of an old pool. How do I get rid of that
reference ?
