Description Dave Wysochanski 2013-07-19 16:15:40 UTC

Description of problem:

Today retrace-server-1.9-6.el6.noarch does not detect vmcores of kernel-rt kernels.  This should be a simple matter of detecting the format of the kernel version and resolving it to the proper kernel-rt-debuginfo package / path.

Version-Release number of selected component (if applicable):
retrace-server-1.9-6.el6.noarch

How reproducible:
Any kernel-rt kernel

Steps to Reproduce:
1. take a vmcore on a system running a 'rt' kernel (For example, 2.6.33.9-rt31.66.el6rt.x86_64)
2. submit to retrace-server
3. fails to identify the kernel-rt-debuginfo package.  it looks like it parses the kernel version ok, may just need some further logic to look for 'el6rt' or something else.

Actual results:
Fail to detect the proper kernel-debuginfo.

Expected results:
Detects proper kernel debuginfo path.

Additional info:
I have an example I can share on our local retrace server.  May need to chat with the rt kernel people to be sure the logic created will work for all rt kernels.
