Hallo digimer, I already knew this link and have read FAQs and other stuff there. Unfortunately, many features such as dependencies between cluster services, that our customers demand from us to be enabled in their clusters (and what they have been accustomed to in their former clusters (e.g. Veritas) which are to be migrated from to RHCS ones) are hardly anywhere documented. But when I posted my query I was mistaken. My ifxdb agent isn't dysfunctional. It really works. But what it still lacks is that clurgmgrd doesn't log its actions despite the fact that I used mentioned ocf_log function (I also check in my agent if that function is defined at run time and if not I resource the /usr/schare/cluster/ocf-shellfuncs) and although it logs every step whenever I run it during disabled services through rg_test utility. I have no explanation why clurgmgrd is so taciturn when it comes to logging output from my ifxdb agent. I think that I have enabled logging up to debug level.
