Had FreeBSD5.1 on a box that had a physical hard-drive failure last =
week.
So, this time setup the box using mirrored 200GB drives using vinum
sub-disks. Setup multiple vinum partitions to help limit any file system
corruption. One of those partitions was /dev/vinum/ports which points to
/usr/ports.
Once the machine was setup with a minimal install, then did a restore =
from
the image made before the original hdd failure. I've never done that =
before,
so there is a possibility that I might have restored a file that I =
should
not have.
Got ports updated using cvsup. Then did a make reinstall of
/usr/ports/x11/kde3. The last thing I saw before fatal trap & reboot was =
the
following:
-------------------

-------------------
Any tips on how to debug this or if there is an article that discusses =
how
to do this I would be very grateful for any help. The only way I know =
how to
fix is to rebuild everything - including setting up the vinum volume up
again. Takes too long, hoping for a better solution. Clearly a newbie.
Thanks,
Richard
