Hi,
I installed FreeBSD5.4 on a server with a 3ware 7006-2 controller and
two 120GB disks as RAID1
I cannot boot this install. (I get some kind of panic or endless loop,
but the display is re-painted so fast I cannot read it).
What I *can* do is insert my SuSE9.2-pro cd1, boot from that and at the
grub-menu say "boot from harddisk".
That boots FreeBSD.
On advice from IRC, I tried:
# boot0cfg -B twed0
-which leads to this output
boot0cfg: write_mbr: /dev/twed0: No such file or directory
This is a erroneous message. The actual problem is:
484 boot0cfg NAMI "/dev/twed0"
484 boot0cfg RET open -1 errno 1 Operation not permitted
This is a known problem with certain MBR layouts. To work around this
problem, set:
sysctl kern.geom.debugflags=16
then try your boot0cfg. There's a protection mechanism that sometimes gets confused by certain partition table layouts. Flag 16 disables that protection. I don't recommend running this unless you are explicitly trying to updating something in a partition table-like area; its very easy to destroy your system with the flag set!
I booted from CD and ran the boot0cfg "offline" - however, this worked only on one server. I have two more identical servers that now just beep endlessly at the F1-prompt.
I was told it is a geometry problem, but what else can I do?
