Bug 57904

Are you using the "hardware" raid features of the hpt370 card or stock Linux
software raid?

The controllers are hpt366, not a card, but on the motherboard. This 
system was set up by somebody else, so I don't know the exact answer 
to your question. However it appears to be a stock Linux software raid, 
judging from the text that scrolls by at boot up.

Boot up the installer, hit ALT-F2 to goto a screen with a shell prompt, and type
'more /tmp/syslog'  and scan through there and see if it detects the hard drive
controllers.  You should see something like (although the particulars will be
different):

If you could tell us what lines have 'IDE controller on' in your syslog that
would help.

Alt-F2 is not getting me into a shell prompt. I am booting from the 
installer CD1. I've tried hitting Alt-F2 at various points during boot up and 
after getting into the GUI install screens, but can't get the shell prompt.

Try <Ctrl><Alt><F2>.  That should get you out of GUI mode and into console mode.

I am having what I believe is the same exact problem.  I am upgrading a machine
running 6.1 with software raid to 7.2 and it is failing.  The machine has two
SCSI drives attached to an adaptec controller (aic7xxx driver) and uses a total
of three parititions:

/dev/sda1 /
/dev/md0  /usr
/dev/md1  /home

The install process sees the '/' partition (/dev/sda1) and then gives the error
about not being able to read partition '/usr'

Matt, do you have any ideas on this one?

I think that we're going to have to write some debugging hooks to see what disks
are being detected and what raid the superblocks say.

Please go to Ctrl+Alt+F2.  Insert a blank MS-DOS formatted floppy.  Type:

mcopy /tmp/syslog a:

and attach that file to this bug.

Do I need to boot from the 7.2 CD to do this, or can I do it while v6.1.92 

is running?

attach /var/log/dmesg from your 6.1.92 and the /tmp/syslog from 7.2 during the
7.2  upgrade process (you'll need to boot from some sort of 7.2 media for that)

Were the RAID arrays set up by the 6.1.92 installer?  Or was software RAID set
up after a stock kernel recompile?

I have no explanation for this, but when I re-booted today from the 7.2 
install CD, it actually recognized my existing partitions and allowed me to 
upgrade. I guess you can consider the case closed. Thanks for your 
help. -Brian

OK, thanks.
