Re: [SLUG] cannot boot Ubuntu with bios raid setting

2009-05-14 Thread Ben Donohue

Hi Ken,

after you set the raid setting, don't you have to then configure a 
logical drive?


what sort of machine is it? server? HP?

also usually when you set it to raid it does not matter what the SCSI 
drive ID is as the raid controller handles this. however i'm not sure of 
this on all hardware.


what happens if you only have one drive in and test? then two and test? 
etc. is each drive recognized on  it's own?  see if you can record the 
scsi id of each.

There is a bios setting for raid and if we set this on we see all 6
harddrives but the install will not boot.

If we set it to not raid we see 4 harddrives and it will boot.

Any suggestions?

The box is a blade server, Xeon Intel board.   In the Raid setting the
drives are still recognised independently in Linux so it is not a true
raid set up.  I know that old DOS machines can only cope with 4 drives,
so I figure it is some sort of compatability mode.Machine is a 64
bit so it could be that I have to use 64 bit install to get it to boot
but I want 32 bit for the XFS recovery,  there is a journalling issue
acording to what I have read.  Ubuntu automatically put a small /boot so
it is not that problem, although that should not matter for a new bios.

I don't need an answer, so much as want an answer so I don't struggle
with this later.

The machine is working 'good enough' and is currently dumping the XFS
file system down using dd_rescue.I am not holding out hope that the
XFS recovery is going to work, 348 gig out of 3.3 terabytes,  1100
errors already.
