Description Jon Thomas 2009-06-16 12:14:01 EDT
Description of problem:


MRG documentation doesn't match kdump documentation for setting up kdump.conf.

It looks like the following should be changed in

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_MRG/1.0/html/Realtime_Tuning_Guide/sect-Realtime_Tuning_Guide-Realtime_Specific_Tuning-Using_kdump_and_kexec_with_the_RT_kernel.html

2. By default, the crash dump is saved in the /var/crash file. If you wish to change this, simply uncomment and adjust the path value in the /etc/kdump.conf file. This can be a local file, or on another server.

2. Kdump can be configured to mount a partition and dump to a file on disk. This is done by specifying the filesystem type, followed by the partition in kdump.conf. The partition may be specified as a device name, a filesystem label, or UUID in the same manner as /etc/fstab. See example below. The default directory in which the core will be dumped is /var/crash/%DATE/ where %DATE is the current date at the time of the cash dump. If you wish to change this, simply uncomment and adjust the path value in the /etc/kdump.conf file. This can be a local file, or on another server. Additional information is provided by the kexec-tools package and is installed at /usr/share/doc/kexec-tools-2.0.0/kexec-kdump-howto.txt.
