4.52. kexec-tools
Updated kexec-tools packages that fix several bugs are now available for Red Hat Enterprise Linux 5.
The kexec-tools packages contain the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot, using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.
Bug Fixes
- BZ#864011
- The vmcore file is generated in the /proc file system. Prior to this update, the kdump (kernel crash collection) service failed to copy vmcore to the desired encrypted target partition. As a consequence, kdump failed to mount rootfs and dropped to a shell. With this update, the user is now notified to not dump to encrypted disks.
- BZ#901620
- A previous version of kexec-tools introduced a regression whereby kdump called findmodule for the ext[234] dump target. As ext2 is built into Red Hat Enterprise Linux 5 kernel, mkdumprd failed with the following error message: "No module ext2 found for kernel 2.6.18-238.5.1.el5, aborting.". To fix this bug, ext2 has been removed from the findmodule list and mkdumprd no longer fails.
- BZ#919369
- Due to incorrect computing of MEMSZ (amount of physical memory allocated to a resource pool or virtual machine), kdump failed to start on Red Hat Enterprise Linux 5 Xen Domain-0 if it had less than 4G RAM. The kdump service also asked for the /boot/vmlinuz-2.6.18-348.el5PAE Physical Address Extension (PAE) location. The kdump kernel service has been set to be non-PAE for systems with less than 4G RAM, thus fixing the bug. As a result, kdump starts as expected.
- BZ#919962
- The makedumpfile(8) manual pages have now been added to the Red Hat Enterprise Linux 5 documentation.
Users of kexec-tools are advised to upgrade to these updated packages, which fix these bugs.
Updated kexec-tools packages that fix one bug are now available for Red Hat Enterprise Linux 5.
The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel. The kexec-tools package provides the /sbin/kexec binary and ancillary utilities that form the user-space component of the kernel's kexec feature.
Bug Fixes
- BZ#915359
- A previous version of kexec-tools introduced a regression whereby kdump called findmodule for the ext[234] dump target, but ext2 was built in the kernel. This caused the mkdumprd utility, which creates an initial RAM file system for use in conjunction with the booting of a kernel within the kdump framework for crash recovery, to fail with a "No module ext2 found" error message. This patch fixes this problem by removing ext2 from the findmodule list and these failures no longer occur.
Users of kexec-tools are advised to upgrade to these updated packages, which fix this bug.
