Hoping someone has some suggestions for helping me recover from these upgrade problems (problems = system will not boot). The system started as F16 with a RT patched kernel from Planet CCRMA. I upgraded to F17 using the install DVD, and after the upgrade install the system console has a continuous stream of messages that MySQL server failed to start, with a suggestion to see the systemd log. The boot process never times out trying to start mysqld, it just keeps repeating the same message forever. I dropped to rescue mode and ran yum upgrade, which only updated a few packages. I thought perhaps the RT patched kernel from F16 was a problem, so I installed the current 3.3.x kernel and rebooted. When the 3.3.x kernel loads, it drops into a shell with only the initrd filesystem mounted, with a message that it cannot find /dev/mapper/VolGroup00_LogVol00 which would usually be my boot drive. The boot drive is (obviously) a logical volume created with LVM, and the physical device underlying the logical volume is a logical unit on an HP P800 Smart Array. The Smart Array is accessed via the cciss driver, but when I look through the /dev/ directory in the initrd image I do not see any /dev/cciss devices. The device is obviously working because grub2 finds the grub menu in /boot, and manages to load the kernel and initrd image. Any idea what might be going on? I'm kind of stuck since neither the old kernel nor the new kernel will boot. Since the installer found the disks OK, presumably I can make some changes by booting the rescue mode of the install DVD. The grub config menu looked OK to me, I can get the details if something was expected to change there between F16 and F17. Maybe something which should have changed in grub config did not. -- Chris Caudle -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
