Hi Michael, you have to emphasize that you already climbed up the learning curve for a while now. :-) It's something totally different to someone knowing Linux but nothing of HAv2. > If I calculate an offer for customers I tell them about five > days. If it > is a standard setup one day. That's a interesting information to hear that you still need a week for a more complicated setup. But anyway: All the replies show that there is not an easy entry to HAv2. It took me many weeks to get a little bit used to HAv2. There are too many issues to learn. Much time is needed to set up some helper scripts, some templates for resource definitions, to get used to the logs, to understand how all subprocesses fit together, to build up a test cluster, to test several scenarios, to accept that the current GUI is (often) not usable, to read the ha mailing list intensivly, to accept that there are still bugs and to find out that different versions may differ in behaviour (which has to be tested). So, IMHO the most time you have to spend on learning HA and the tools and building up a usable test cluster (and if you don't have the money to replicate the production system you have to live with an approximation, e.g. other stonith devices, other network components) Still learning every day somthing new about HAv2.
