Hi,
as far as I know my disk is not operating in dangerously dedicated mode.
Despite this I'm unable to upgrade to freebsd 8.0. Here is what the
gpart, mount, bsdlabel say.
gpart show
=> 63 488397105 ad4 MBR (233G)
63 488392002 1 freebsd [active] (233G)
488392065 5103 - free - (2.5M)
=> 0 488392002 ad4s1 BSD (233G)
0 2097152 1 freebsd-ufs (1.0G)
2097152 16777216 2 freebsd-swap (8.0G)
18874368 16777216 4 freebsd-ufs (8.0G)
35651584 4194304 5 freebsd-ufs (2.0G)
39845888 83886080 6 freebsd-ufs (40G)
123731968 188743680 7 freebsd-ufs (90G)
312475648 175916354 - free - (84G)
mount
/dev/ad4s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad4s1g on /jails (ufs, local, soft-updates)
/dev/ad4s1e on /tmp (ufs, local, soft-updates)
/dev/ad4s1f on /usr (ufs, local, soft-updates)
/dev/ad4s1d on /var (ufs, local, soft-updates)
bsdlabel ad4
bsdlabel: /dev/ad4: no valid label found
bsdlabel ad4s1
# /dev/ad4s1:

partition c: partition extends past end of unit
bsdlabel: partition c doesn't start at 0!
bsdlabel: An incorrect partition c may cause problems for standard
system utilities
I remember problems with the initial sysinstall because of geometry
problems -- the only way to get FreeBSD installed was to dedicate all of
the available space to FreeBSD.
I've found a suggested solution to repair the mbr/label problem with
dd if=/dev/zero of=/dev/ad4 count=1 oseek=1
and a warning not trying it on boot disks.
Is there a better / safer solution around?
Thanks
Reinhard
