Synopsis

netdump bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated netdump-server packages that fix various bugs are now available.

Description

The netdump server listens to the network for crashed kernels to contact
it. It then writes the oops log and a memory dump to /var/crash before
asking the crashed machine to reboot.

Previously, removal of the /var/crash subdirectory followed by a netconsole
log message or system crash caused the netdump-server daemon to fail the
operation. It is now possible to create /var/crash on the fly if needed.

If a properly configured server was set in the /etc/sysconfig/netdump file
but was unreachable or was unresolvable at module load time, netdump no
longer fails.

The package README file has been updated to indicate that alt-sysrq-c or
/proc/sysrq-trigger should be used to forcibly crash a kernel.

If any of the netdump-server script files fails, a syslog message will
be issued.

If a requested page from a netdump client consists of all zeroes, then
sparse file space will be used in the vmcore instead of writing out a page
of zeroes.

The netdump-server source code has been cleaned up so that there are no
compile-time warning messages.

The netdump-server closes the vmcore file before executing the
netdump-reboot script, allowing commands in the script that operate on the
vmcore to run successfully.

/etc/sysconfig/netdumphas been designated %config(noreplace) in the
netdump.spec file.

Users of netdump-server should upgrade to these updated packages, which
resolve these issues.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
