kdump test fails after switchting to summer time / daylight saving time
Last modified: 2013-07-03 03:37:41 EDT
Description of problem:
Germany switched to summer time (CEST) last weekend. Last week I performed 32-bit kdump tests on a test system and they passed. Today I performed the same tests with 64-bit and I failed.
Version-Release number of selected component (if applicable):
Actual version of v7 testsuite
Steps to Reproduce:
1. Install RHEL 6.2
2. Set HW clock to UTC and time zone to Europe/Berlin
3. Perform local kdump test
The test fails. The logs say, that no crashdump in a good time window could be found in /var/crash.
kdump should work, regardless of the time and timezone settings.
Looking into /var/crash shows that the crashdump file is always 1 hour advanced to the real time.
Meanwhile I managed to pass the test with the following time settings:
- System clock is running on UTC
- System time zone is GMT-1h.
Looks like the change to summertime was messing things up. ;-)
Hi Rainer, is this still an issue? IIRC, the problem should no longer exist several hours later after switched to summer time.
Hrm, I'm pretty certain nothing in v7 is daylight aware. But it's worth confirming the issue does self resolve after a few hours or is there a period of time (days weeks months) where the various time zones being at different offsets continues to effect the test?
