This command initiates that the gjournal geom is disconnected from his
gmirror geom and afterwards the geom "automatic magic" called "tasting"
takes place to find a new matching geom for the gjournal geom. The
result is: The ufsid geom says: Yes I will.

The asynchron running stop is still active, and the play begins again ...

On servers using gmirror/gjournal/gpart I always have the following
lines in my loader.conf to prevent the problems you saw:

kern.geom.label.gpt.enable="0"
kern.geom.label.gptid.enable="0"
kern.geom.label.ufs.enable="0"
kern.geom.label.ufsid.enable="0"
