mogadm host delete not so good?

We have some old mogile storage nodes that I wanted to take out of the
cluster and out of the mogile to reduce clutter in the output of
mogadm. About two weeks ago I marked all devices on the host as 'dead'
and based on the database activity, it looks like their files got
replicated elsewhere. The machine has been idle for pretty much a week
so I decided it would be okay to purge it from mogile.
I did this:
# mogadm host delete OLDHOST
And pretty quickly nothing worked. Looking at the daemon log, it
appears the tracker does not like having a host go MIA so it dies.
Dec 21 14:40:41 AF001079 mogilefsd[5728]: crash log: No host for dev 6
(host 4) at /usr/bin/mogilefsd line 329.
Dec 21 14:40:41 AF001079 mogilefsd[5728]: ending run
Dec 21 14:40:43 AF001079 mogilefsd[9415]: Child 5728 (monitor) died: 0
(UNEXPECTED)
I recovered by going into the database and manually re-adding the row
for the host (setting its status to 'dead'). This appears to have
addressed the big failure.
My question: is there any way to remove a device from mogile and if so,
what is the correct procedure?
Thanks,
B-
