hmm, i'm sure i've attached the logs...

ok, that tiny "-4" should explain the "false" behaviour with groups ;o)

i'm continuing my tests with an interim build - but i'm not willing to 
run such an unreleased version in a production-environment :o(

(better i use no groups at all and configure everything as single 
resources with some more order- and colocation-constraints...)

BTW: how do i configure the CTS correctly?

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).

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.

everything works fine except that the test dindn't run the stonith-tests?
