** Description changed: + SRU Request for Lucid/Maverick/Natty/Oneiric: + + [Impact] - When a server is configured with the /boot as a separate + partition, which is the default configuration when LVM installation is + selected, the kdump mechanism fails systematically. + + [Development/Stable Fix] - This has been fixed in the development + version with the addition of the following: + + * Backport changes to fix kdump functionality. LP: #828731. + - debian/kdump.initramfs: call /usr/bin/makedumpfile via a chroot command, + so that if makedumpfile is statically linked, we get proper library + resolution. Thanks to Louis Bouchard <louis.bouch...@canonical.com> for + the patch. LP: #785425. + - debian/kdump.initramfs: handle the possibility that /usr, /boot, or + /var is on a separate filesystem and needs to be manually mounted before + calling makedumpfile. LP: #828731. + - Depend on makedumpfile, without which the initramfs script doesn't work. + - Fix an unnecessary bashism. + - Only install the kdump initramfs script and depend on makedumpfile on + architectures that makedumpfile supports. + + [Test Case] - See 'how to reproduce' below. + [Regression Potential] - Need to ensure kdump works correctly in backported versions. + + -- + Binary package hint: kexec-tools This concerns kexec-tools 1:2.0.1-2ubuntu4 in Ubuntu Natty. I am trying to get a kernel crash dump. Instead of getting a nice vmcore file in /var/crash/, I get a vmcore.log file with the following: /root/usr/bin/makedumpfile: error while loading shared libraries: libdw.so.1: cannot open shared object file: No such file or directory Problem number 1: /usr/bin/makedumpfile is a dynamically-linked executable. Not the kind of thing you want to run in an initramfs environment. There is, however, a "makedumpfile-static" package, which not only provides /bin/makedumpfile-static, but also an initramfs-tools hook so that this statically-linked binary is copied in as /bin/makedumpfile in the initrd. Problem number 2: The 0_kdump script is hard-coded to use the dynamic binary in root:/usr/bin/. It is not at all aware of initrd:/bin/makedumpfile .
