FreeBSD 8.1 - boot failures (upgrades and clean installs) - root
FS corrupt?

Hi all
I'm striking some trouble attempting to upgrade (and also in building a clean
replacement) for an existing 8.0-RELEASE-p3 system running in a virtual
machine. The host is Hyper-V R2 and 8.0 has been just fine and dandy.
Upgrades and installation generally appear to go fine - no error messages that
I can see - but in each case on restarting the system I get only a black
screen with a single hyphen on the second line, and the cursor flashing
underneath it.
Leaving the VM for many minutes does not improve matters - but a Ctrl+Alt+Del
does restart it, so it's not "hung" per se. It just fails to start.
This is the result of a clean installation:
The VM configuration is simple enough - a 64GB disk on IDE 0/0, a DVD on IDE
1/0, an Intel 100Mbps network card (de0), 2 CPUs and 1GB of RAM. Booting the
Fixit shell from the DVD - fdisk shows the disk partitioned, seemingly
correctly. I've created partitions like so:
ad0s1a = 2GB = /
ad0s1b = 2GB = swap
ad0s1d = 10GB = /var
ad0s1e = 48GB = /usr
ad0s1f = 2GB = /tmp
Mounting them shows the root volume seemingly has data:
Fixit# df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/md0 39561 3051 900 77% /
devfs 1 0 0 100% /dev
/dev/acd0 2251930 2251930 0 100% /dist
/dev/ad0s1a 2026030 272730 1591218 15% /mnt/root
/dev/ad0s1d 10154158 194 9341632 0% /mnt/var
/dev/ad0s1e 48745002 695558 44149844 2% /mnt/root
Fixit#
Yet the 15% of used space is ... well not used properly:
Fixit# ls -la /mnt/root
total 0
Fixit#
fsck_ffs /dev/ad0s1a produces errors for many (all?) inodes - as if file
writes were not properly completed / flushed. When fsck is completed, all
contents are in lost+found as inode numbers.
Any suggestions on debugging what's going on? I'd really like to be able to
get current.
Dave.
