Description Nicolas CROISET 2002-11-06 04:49:56 EST

Description of Problem:
When you install redhat 8.0 or redhat 7.2 with two hard disk one in hda and the
other one in hdc. These two harddisk are identical (IBM 41 GB IC35L040AVVA07-0).
The motherboard is a rocky-3702EV-V4.

hda is discover as : 2005 cyl / 255 heads / 63 sectors
hdc is discover as : 79780 cyl / 16 heads / 63 sectors

This is a little problem when you make RAID 1 in soft.
If you modify these values by hand with fdisk to makes it identical via redhat
interface, these values are not saved.
If you modify these values by hand via a tty console these values are correctly
saved.

When you return via the graphic interface, linux redhat installer find that hdc
is not good when you make back and next...

The good solution is to find the same number od fectors/head and cylinders in
hda and hdc when you have identical disks.

when you put these harddisks in hda and hdb, the values are identical.

I do the same test on another machine which have the same motherboard and the
same hardisks, the problem is the same so it's not a hardware problem.

In the bios in autodetect mode, the harddisk are configured identical.

Are the primary and secondary IDE controllers on your system using the same IDE
chipset?

This appears to be a kernel geometry detection issue.

The website of this motherboard is at :

In the file /etc/sysconfig/hwconf, I have these informations :

We had forced the logical via the console to have the same on the two harddisks.

I hope this will help you a little.

Comment 3 Alan Cox 2003-06-05 08:38:06 EDT

The kernel pulls hda/b info from the CMOS data but cannot do so for hdc/hdd.
This can lead to slightly different sizes being apparent for the two disks but
that isnt a problem, the raid layer will adjust a mirror appropriately to fit
the slightly smaller drive.

Using fdisk to set the geometry works. I wonder if the installer simply cached
the data.

If this is the case I would suspect parted.
