While 'zdb -l /dev/dsk/c7d0s0' shows normal labels. So the new question is:
how do I tell ZFS to use c7d0s0 instead of c7d0? I can't do a 'zpool
replace' because the zpool isn't online.
ZFS actually uses c7d0s0 and not c7d0 - it shortens output to c7d0 in case it
controls entire disk. As before upgrade it looked like this:
NAME STATE READ WRITE CKSUM
datapool ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c2d0s0 ONLINE 0 0 0
c3d0s0 ONLINE 0 0 0
c4d0s0 ONLINE 0 0 0
c6d0s0 ONLINE 0 0 0
c5d0s0 ONLINE 0 0 0
I guess something happened to the labeling of disk c7d0 (used to be c2d0)
before, during or after upgrade.
It would be nice to show what zdb -l shows for this disk and some other disk
too. output of 'prtvtoc /dev/rdsk/cXdYs0' can be helpful too.
This is from c7d0:

Labels 1-3 are identical
The other disks in the pool give identical results (except for the guid's,
which match with what's above).
c8d0 - c11d0 are identical, so I didn't include that output below:
