dmraid problems - Intel ICH9R raid not recognized by Fedora 10 Preview
 
Hi everyone,

Posting another dmraid bug in Fedora 10 preview. As requested by Jesse Keating.

https://www.redhat.com/archives/fedora-devel-list/2008-November/msg01108.html


Server: PRIMERGY RX100 S5
Make: Fujitsu Siemens Computers
Processor: 1x Xenon Quad Core/ 2xSATAII 500GB / RAID chip Intel ICHR9
/motherboard FSC
Will be affecting also PRIMERGY Econel Servers with RAID chip Intel ICHR9


We have configured a RAID 1 array on Intel ICH9R raid. Which in fact uses LSI
firmware and appear like LSI Software SATA RAID Bios Version: A.06.05071459R

This is a fakeRAID so dmraid is used to deal with it.

A) Using Fedora 10 Preview the RAID array is not recognized at all.
In the anaconda installer just appear 2 separate SATA disks.

B) Using Fedora 9 and Fedora 10 Beta the RAID array is recognized but when
booting appears an error message which is actually not affecting the
functionality of the OS (The system boots up OK). Not sure of dmraid (RAID) functionality in case of a crash.

Error:
<SNIP>
Setting hostname localhost.localdomain [OK]
/etc/rc.d/rc.sysinit: line 350: 1336 Segmentation fault /sbin/dmraid.static -ay
-i -p
"$dmname" > /dev/null 2>&1
Setting up Logical Volume Management : 2 logical volumes........
</SNIP>

Version-Release number of selected component (if applicable):
F10 Preview x86_64 DVD
F10 Beta x86_64 DVD
F9 Release x86_64 DVD

I thing there is something seriously wrong with dmraid in F10. Anybody out there with similar experience.
We have planned to use F10 on our servers if solution would be provided.

I have posted a bug: https://bugzilla.redhat.com/show_bug.cgi?id=471737

Best Regards
