http://bugzilla.opensuse.org/show_bug.cgi?id=964989 Bug ID: 964989 Summary: /sbin/update-bootloader --refresh just hangs on truncated /boot/grub2/grub.cfg Classification: openSUSE Product: openSUSE 13.1 Version: Final Hardware: x86-64 OS: openSUSE 13.1 Status: NEW Severity: Major Priority: P5 - None Component: Bootloader Assignee: jsrain@suse.com Reporter: tilman.vogel@web.de QA Contact: jsrain@suse.com Found By: --- Blocker: --- Due to an out-of-space issue on a too small /boot partition, a recent kernel update produced a null byte /boot/grub2/grub.cfg file. It however, still had written a /boot/grub2/grub.cfg.new which I then copied to /boot/grub2/grub.cfg . Booting with this worked after I had rebuilt the initrd, even though the submenus did not show in grub2. After that I wanted to run purge_kernels but found out it hanged in update-bootloader. Also the YaST boot-loader module hung at "reading boot loader configuration". Looking at the /boot/grub2/grub.cfg.new, I found that the file indeed was incomplete, probably because of the out-of-space situation. After cp /boot/grub2/grub.cfg.old /boot/grub2/grub.cfg, /sbin/update-bootloader --refresh now works. I recommend checking for EOF when reading /boot/grub2/grub.cfg even when expecting further data. In that case, a hint about /boot/grub2/grub.cfg.old should be given or the option to generate it completely anew. -- You are receiving this mail because: You are on the CC list for the bug.
