RHEL4.8x86 GA hts5.3-15 fails Profiler/Storage test with 10G nic VC Flex10 environment
Last modified: 2014-03-25 20:56:56 EDT
Description of problem: RHEL4.8x86 GA hts5.3-15 fails Profiler and Storage test with 10G nic VC Flex10 environment. But the test passed with 1G nic environment. This is a Blade AMD platform server
Version-Release number of selected component (if applicable):
RHEL4.8x86 GA release
Steps to Reproduce:
1. Install RHEL4.8x86 GA onto SUT with 10G nic VC Flex 10 environment
2. Open modprobe.conf
3. Add "options oprofile timer=1" to the end of the file and reboot
4. Installl hts5.3-15
5. Run hts plan
6. hts run --test profiler and hts run --test storage
7. Tests failed.
Actual results: Failed
Expected results:Should pass as 1G nic environment
Additional info:See attached log
So far we only see this issue on AMD platform. Not sure on Intel platform.
Garry, do you have the logs which show this failure? Also it might be work a look into if hts-5.3-17 solves the issue, though I suspect the profiler change in -17 is unrelated.

See attached logs. We will verify with -17 and update you.
Thanks for your time.
I'm not certain if this is still an issue but the storage failures are caused by the partition setup:
Error: cciss/c0d0 is currently in use by LVM.
It cannot be tested. You may need to reinstall.
...finished running ./storage.py, exit code=1
...and the oproile failures are caused by this...
Failed to open profile device: Cannot allocate memory
Using 2.6+ OProfile kernel interface.
Couldn't start oprofiled.
...which IIRCis caused by the irq timer resource being taken by the nmi_watchdog, this can be worked around by disabling the nmi_watchdog or setting the oprofile option to use the software timer via "options oprofile timer=1" in modprobe.conf.
The LVM issue still exists but the timer mode should be worked around in the test suite itself now.
