Red Hat Product Errata RHBA-2010:0295 0 normal SHIPPED_LIVE mkinitrd bug fix and enhancement update 2010-03-29 14:21:24 UTC

Description Hans de Goede 2009-09-29 13:39:37 UTC
There is an error in the mkinitrd script which causes it to try and explicitly activate the subsets of a (nested) raid 10 set, causing error messaged during boot like these ones:
https://bugzilla.redhat.com/attachment.cgi?id=354680

These errors are ugly, but otherwise 100% harmless.

This patch fixes these error messages:

Comment 1 RHEL Program Management 2009-09-29 14:20:12 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

Comment 3 Hans de Goede 2009-11-05 15:12:42 UTC
As I filed this I guess I should take care of it.

Note, in case you beat me to fixing this, the proposed patch:
https://bugzilla.redhat.com/attachment.cgi?id=355550  

Has 2 issues:
1) dmraid should be invoked with -i
2) The output of dmraid should be checked to not be "no dmraid disks"

Comment 4 Hans de Goede 2009-11-24 09:12:51 UTC
This is fixed in mkinitrd-5.1.19.6-55 .

Comment 6 Alexander Todorov 2010-02-17 13:41:59 UTC
Hans,
any hints how we can test this?

Comment 7 Hans de Goede 2010-02-17 13:50:15 UTC
Hi,

(In reply to comment #6)
> Hans,
> any hints how we can test this?    

Take a machine with Intel BIOS RAID, put 4 disks in it, make it
a RAID10 set in the Intel OROM, install 5.4, boot, watch ugly error messages.

Install 5.5, boot again, error messages are gone.

Note that I have such a machine and have already gone through the above motions, iow the fix actually fixing things was already verified by me.

Regards,

Hans

Comment 8 Alexander Todorov 2010-02-17 15:04:48 UTC
OK, moving to VERIFIED then. RTT doesn't have easy access to systems with Intel BIOS RAID anyway.
