Hi,
I have a server set up to boot from a gvinum mirror volume. This was
all working fine, so I then proceeded to load my data on it, safe in
the knowledge that all was well.
However, all was not well after the last reboot: it seems that while
the two ATA disks probe, for some odd reason GEOM does not create
device entries in /dev for one of the disks, while gvinum has gotten
totally confused and thinks that the plex on the disappearing disk is
still up!
See the attached log for lots of details. All of this is on
FreeBSD 5.4-RELEASE #2: Sun May 8 09:56:34 CEST 2005
Can anyone tell me:
- how to force GEOM to 'taste' ad6 and therefore create the /dev entries?
- how to tell gvinum that ad6 is really gone so that it will be forced
to sync my data on ad6 after the GEOM problem is fixed?
- the clue to how the machine has gotten in such a confused state?

I really hate this damned machine
I wish that they would sell it.
It never does quite what I want
But only what I tell it.
