Good news and bad news. mkinitrd-5.1.19.6-44 only shipped in 5.3, and since the 1.1.1 candidate was shipped for 1.1, we support 5.2. This will have to be revisited, though, when the next release goes out that targets 5.3. Created attachment 333925 [details]
Patch for the mkinitrd/dmraid issue
One possible solution.
This patch creates a functions called try_findmodule(), used only to locate dmraid modules, that will silently ignore these modules if they are not present in the kernel being installed.
By the number of reports we received about the mkinitrd WARNINGS during MRG RT kernel installation, I believe support folks will like this solution best as it may avoid bogus support tickets.
before:
# mkinitrd /boot/initrd-2.6.24.7-107.el5rt.img 2.6.24.7-107.el5rt
No module dm-mem-cache found for kernel 2.6.24.7-107.el5rt, aborting.
After:
# mkinitrd /boot/initrd-2.6.24.7-107.el5rt.img 2.6.24.7-107.el5rt

Another patch for the mkinitrd/dmraid issue
Another possible solution [ just for the sake of completeness as the other patch is better ].
This patch creates a functions called try_findmodule(), used only to locate
dmraid modules, that will ignore these modules if they are not present
in the kernel being installed, but will issue the scary warning from mkinitrd.
By the number of reports we received about the mkinitrd WARNINGS during MRG RT
kernel installation, I believe support folks will preffer the other solution as it may avoid bogus support tickets.
before:
# mkinitrd /boot/initrd-2.6.24.7-107.el5rt.img 2.6.24.7-107.el5rt
No module dm-mem-cache found for kernel 2.6.24.7-107.el5rt, aborting.
After:
# mkinitrd /boot/initrd-2.6.24.7-107.el5rt.img 2.6.24.7-107.el5rt
WARNING: No module dm-mem-cache found for kernel 2.6.24.7-107.el5rt, continuing anyway
WARNING: No module dm-region_hash found for kernel 2.6.24.7-107.el5rt, continuing anyway
WARNING: No module dm-message found for kernel 2.6.24.7-107.el5rt, continuing anyway
WARNING: No module dm-raid45 found for kernel 2.6.24.7-107.el5rt, continuing anyway
The fix for BZ#479270 already addressed this issue. RHEL5.4 has this fix on the default installation. The relevant changelog entry is: * Fri Apr 17 2009 Peter Jones <pjones> - 5.1.19.6-45 - Supress failures if dm-raid45 modules are not present. Resolves: rhbz#479270 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2010-0771.html |
