Product: Fedora Version: rawhide Component: kernel Marcus Haebler <haebler@xxxxxxxxx> has asked for fedora_requires_release_note: Bug 468649: dmraid/isw cannot access ICH10R RAID metadata on member disks https://bugzilla.redhat.com/show_bug.cgi?id=468649 ------- Additional Comments from Marcus Haebler <haebler@xxxxxxxxx> Description of problem: There are three disks in the system. The first two (sda & sdb) are configured as a RAID 1 on an Intel fake RAID (P45/ICH10R). The third disk (sdc) is a single disk and not configured into the RAID in any way. The kernel/installer in F10 Snap 3 x86_64 DVD does not recognize the RAID 1 and lists the member disk in the installer (anaconda). Interestingly, when I tried the F10 Beta the RAID was properly recognized but the system crashed otherwise during the install. With Snap 3 I actually managed to install it on sdc. But I did not write GRUB out to one of the member disks for fear of destroying the RAID 1, I simply put GRUB on SDC - hoping to use that to boot Linux from boot.ini on XP. During the post package install phase - probably when writing GRUB to sdc I saw the following error messages: ERROR: isw: Could not find disk /dev/sdb in the metadata ERROR: isw: Could not find disk /dev/sda in the metadata I managed to reproduce the by booting the rescue kernel. They appear after mounting the installed partitions on sdc. Version-Release number of selected component (if applicable): F10 Snap 3 x86_64 DVD, kernel reports version 2.6.27.3-34.rc1.fc10.x86_64, dmraid (library) has version 1.0.0.rc15 , device-mapper is 4.14.0 How reproducible: Reliably reproducible by running the rescue kernel, will appear after the disk mounting or simply by calling "dmraid -r" from the command line. Interestingly it lists /dev/sdb before /dev/sda. Steps to Reproduce: 1. boot rescue kernel from DVD: "linux rescue" 2. Let it mount partitions on sdc 3. Error will appear after mount or by calling "dmraid -r" Actual results: ICH10R RAID1 not recognized by kernel Expected results: ICH10R RAID1 recognized and shown via device mapper. Additional info: The RAID1 is formatted as NTFS. All three disks are the same size (1TB). RAID1 status was reported as healthy ("Normal") by the BIOS before booting into Linux. Verified RAID1 is healthy in XP as well. Using Intel Storage Manager 8.6. Write-Back cache is enabled. -- Fedora-relnotes-content mailing list Fedora-relnotes-content@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-relnotes-content
