question is:
a. how to use "zpool add" to add the 2nd partition to rpool - which
should be c7d0p2, right?
when I did this:
zpool add rpool c7d0p2
cannot add to 'rpool': root pool can not have multiple vdevs or
separate logs
what do u mean by "separate logs"?
That is the right command.
However, the rpool as a special case is not permitted to be RAID 0
(multiple vdevs) as you were attempting, only RAID 1 (mirrors).
b. assuming that it is NOT possible to add the 2nd partition to the
zpool rpool, then how do I used fdisk (or whatever) to modify the
partition table, so that the entire disk belong to the zpool rpool -
instead of just c7d0p1 now allocated to zpool rpool?
It can be done by careful use of fdisk (with some risk of blowing away
the data if you get it wrong), but I've seen other email threads here
that indicate ZFS then won't mount the pool, because the two labels at
the end of the partition can't be found anymore (having moved where the
end of the partition is).
You could create a separate zpool in the spare fdisk partition. Not good
for performance, but probably fine for infrequently accessed data.
