Hi,
I recently joined the lkcd mailing and I have a newbie
question. I am fairly new to Linux.
I see there are two version of SVR4 UNIX crash-like
utilities for Linux:
1. crash2.5 : http://www.missioncriticallinux.com/technology/crash/
2. lcrash 3.0 : http://oss.sgi.com/projects/lkcd/
Is there any documentation/FAQ available that describes the
difference between two, pros/cons, etc ? I tried to look
thru the online documentation on each site and deja news,
but could not find any relavent info. If someone had
hands-on experience with both utilities, could you please
share ?
We (in NCR Corp) is looking into porting one of the existing
software product (Teradata RDBMS) on Linux and this product
has the kernel device driver which will be implemented as
loadable module. I would be interested in knowing whether
lcrash3.0 currently provide the following capability:
README file in crash2.5 stated as one needs to recompile
the kernel with -g option (to get debug symbol info).
Does lcrash3.0 require for kernel to compie with -g option
as well ? Because -g option for kernel build may not be
desireable for the kernel running on a production box.
It would be nice to be able to use lcrash for analyzing Linux
panic dumps (as well as live system) that have kernel compiled
with/without -g option. This same question also goes to
kernel module as well. I see lcrash3.0 provides the
'Kerntypes' target and perhaps this is the way to load the
kernel symbol information for non-debug kernel (?).
Thanks in advance,
