Description Melvin Yam 2004-11-27 10:12:49 UTC

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET 
CLR 1.1.4322)

Description of problem:
I have a Gigabyte 7VAXP-A Ultra M/B that comes with a Promise 
PDC20276 chipset.
I have 2 80GB configured as RAID0 and have about 20GB of free space.
I tried to install Fedora Core 3 onto this free space.
When I boot Fedora Core 3 on DVD,
it boots and went into anaconda graphics installer.
When I come into disk partitioning, it ask me which harddisk
I want to install onto. Apparently it seems to detect my RAID0
as 2 separate hard disk.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Boot Fedora Core 3 on DVD

Actual Results:  Does not detect my RAID0 as a single drive

Expected Results:  Detect my RAID0 as a single drive

sounds like you configured your raid using the promise BIOS tool.
Anaconda will only detect Linux software raid partitions.

ISTR there's a device mapper target module to support the various raid
controller disk formats, but I'm not sure of its status wrt merging. Alasdair ?

Comment 2 Melvin Yam 2004-11-29 02:17:51 UTC
There are a lot of motherboards with Promise RAID.
I hope Fedora can support these motherboards with RAID.

Comment 3 Heinz Mauelshagen 2004-12-03 15:34:50 UTC

dmraid is the tool supporting various ATARAID formats (such as the one
in this case). It reads the vendor specific metadata and converts
it into device-mapper tables in order to activate respective mapped devices
for each RAID set.

Talked to Jeremy ysterday about the missing early boot integration of dmraid
in FC>2/RHEL-4.
He hasn't had the time to look at it yet.

Comment 4 Dave Jones 2005-07-15 19:56:00 UTC
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
