Red Hat Bugzilla – Bug 18183
RAID install fails if you have IDE + SCSI
Last modified: 2008-05-01 11:37:59 EDT
On RH 6.2 I had a working install with 3 drives. hda and hdb are
identical, and were
my software raid 1 set for mirroring and I booted off of that. My sda is
used for storing database
information. The machine is a Dell Precision 410. It has 2 400MHZ PII
motherboard has a built-in adaptec controller that was controlling the IBM
Anyway, when trying a fresh install I figured ok, I'd just wipe everything
set up raid as part of the install [instead of doing it later like I did on
rh 6.2]. When
trying this, the install said I could only use hda and sda, since those are
2 drives. Actually, hda and hdb are the first 2 drives on my machine.
I did an upgrade and the RH7 seemed to work with my existing md0 raid1 set
I think this is a logic bug in your installer somehow since most people
2 ide drives and a scsi drive and then choose to make an md0 set out of the
drives and boot off of that.
So the workaround is either upgrade, or install the hard way [just install
on hda, then
later set up software raid and let it rebuild hdb as part of a recovery].
Still, for rh 7.1
you might wanna fix this problem, or document it.

Brent please try this out with roswell.
Ok, looking at this now.
This works fine for me with our latest tree. All of the partitioning code has
been replaced with *new-and-improved* partitioning code, so it looks like this
problem has disappeared. Thanks for your report.
