Description Zhenyong(Jerry) Jiang 2008-07-22 03:09:21 UTC
Description of problem:

Anderson wrote kdump can support full dump or kernelpages only dump in

But in RHEL5.2 kernel-doc, kdump.txt says this function is in "TO DO" list. will
we bring this function into RHEL5.3?

in some of my cases, some servers has 16GB or more memory, a full dump will
create a huge file. It will cost 1-2 days to transfer it to redhat.

Some other customers want to protect their data, they wishes kdump not collect
the user-space pages. They know disk-dump can support it in RHEL4.

Could we implement it in RHEL5.3.

Comment 1 Neil Horman 2008-07-23 11:18:14 UTC
This has been implemented since GA iirc, using the makedumpfile utility, which
is configurable automatically through kdump using the core_collector option in
/etc/kdump.conf.  See man makedumpfile (specifically the -d option) for details
of usage
