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 . |
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.bouchard@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.
