You are using gpt/* labels in this pool and there is no use for glabel(8)
functionality since you already have the disk labeled by gpart(8).
If you would like to use glabel(8) instead then your pool will need to be
pointed to those devices like so:
zpool create tank raidz2 label/disk{0,1,2,3,4}
If you were to use glabel(8) on any other disk that has been setup to not
use the generic label/* then the result of using glabel(8) would be to the
same effect as writing to parts of your pool and destroying the data that
is already on it causing the situation that you see here.
To say the least... choose one or the other but not both.
