Hello,
I'm running 5.4-RELEASE with geom_{mirror,gate}.ko and the various
geom, gmirror and ggate[cd] userland libs/tools built from a fairly
recent CVSup (8/Aug).
Having successfully setup gmirror to link a local and remote device
together, I wanted to test what happens when the remote machine "dies",
so I've simulated that by killing the ggated process. As expected
ggatec notices, as does gmirror and the array is marked degraded.
I then set about a recovery procedure: I restart ggated on the "dead"
machine then destroy and re-create the ggatec unit -- so that gmirror
picks it up the change, which it does. However it then barfs with
"Component ggate0 (device test) broken, skipping" and I get the
following with kern.geom.*.debug*=1 :-
- ----8<--------8<--------8<--------8<--------8<--------8<----

Am I doing something wrong, or is this a bug?
