hi!
I made these changes to the cib:
colocation syslogng2mysql_on_nagios-group inf: nagios-group
syslogng2mysql
order nagios-group_then_syslogng2mysql inf: nagios-group:start
syslogng2mysql:start
Then went one by one the resource of resource group "nagios-group" down, only
"fs_drbd1" and "fs_drbd" were started.
Maybe the whole resource group was going down, but the stop timeout values
(360s) could lengthened the resource-group stop process.
After that the resource group and the new service (in correct order) started.
-> very good!
The test "crm resource stop syslogng2mysql" stopped the resource, and again,
the resource group. why?
And in syslog I found that the lrmd tried to start the resource
"syslogng2mysql" on the other node, that did not was master of resource-group
"nagios-group".

only these resources from the group stopped?

the following should work, i don't think you need to specify the start but I do
it in order to read the rule easier.
order nagios-group_then_syslogng2mysql inf: nagios-group:start
syslogng2mysql:start

where is the colocation for start fs resource on the Master ms-drbd?
You need to make sure that the fs_drbd1 and fs_drbd2 run on node with the role
master for ms_drbd1 and ms_drbd2.
