Hi,
When using software based RAID controllers (e.g. ICH9R) in RAID-1 =
scenario, if any of the drives fail and the server reboot, the system =
will not come back up.
This has been observed on FreeBSD 6.3-RELEASE i386 with following error:
Fatal trap 12: page fault while in kernel mode
fault virtual address =3D 0xf4d988d8
fault code =3D supervisor read, page not present
instruction pointer =3D 0x20:0xc0847e06
stack pointer =3D 0x28:0xc0c20bfc
frame pointer =3D 0x28:0xc0c20c40
code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, def32 1, gran 1
processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 0 (swapper)
trap number =3D 12
panic: page fault
I wasn't able to get the machine up into any mode except to the basic =
prompt.
This problem can also be duplicated if you move the drive from ICH9R =
RAID to non-RAID controller
Any tips on how to get the FBSD system operational again without having =
to do a reinstall?
Thanks,
Tamouh Hakmi
