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).
Here is the error when booting from disk 0
BIOS drive C: is disk0
BIOS drive D: is disk1
zio_read error: 5
zio_read error: 5
ZFS: i/o error - all block copies unavailable
ZFS: can't read MOS of pool zbackup1
ZFS: can't find pool by guid

and it continues on from there and boots
After I did the zpool upgrade zroot, I did
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1

Whats odd is that zbackup1 is not the name of the pool. Where is that
coming from ? The pool I boot from is zroot on this box

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 ?
