BTW: how do i configure the CTS correctly?
Ideally you'll want to run CTS from a third machine - the test exerciser
- that monitors the behavior of the two nodes in the cluster. The ha.cf
and heartbeat version should be the same on all three machines, and
syslog-ng should be setup to send messages to the exerciser.
when i explicitely enable stonith-testing with the command:
python ./CTSlab.py -v2 --stonith yes --standby yes 5 > /tmp/cts_output
2>&1 &
then none of these tests are executed (see attached logfile).
You did enable stonith tests, but tests are chosen randomly from all
runnable tests, so with only 5 tests your chances of running stonith are
small. If you want to run just one type of test, you can use the
--choose option to do so (i.e. --choose stonith).
stonith is enabled and configured to reboot failed nodes. a
stonith-clone with "apcmastersnmp" is configured, running and working
(tested earlier by hand). startup-fencing is enabled.
CTS comes with it's own built-in configuration (it generates its own
CIB), and the stonith device it uses is ssh. So even if you have
apcmastersnmp setup correctly, it will not be used by CTS.
before writing about this issue i've already set up everything according
to the cts-README-file. Also the tests are already running BUT i didn't
know that the cts is for testing the cluster-software only, not my
previously written cluster-configuration with all its resources and
constraints...
that's not really clear in the README-file (except the ssh-plugin for
StonithdTest). Also i didn't know that the tests are run randomly on the
nodes based on the given iterations.
IIRC the option "--choose" isn't documented in the README - are there
sources for a complete description what the CTS do in detail and how to
configure all these details? Is there also a way to test the cluster
with my own resources configured?
