I mostly concur on this.
It all has a steep learning curve, log files are far from transparent but the
principles are quite clear to me and the possibilities are endless. It's the
ultimate way to have an alternative for very expensive clustering solutions. I
already built two HA setups were the storage is made out of two DRBD nodes
offering iSCSI and several nodes which are HA Xen hypervisors. I'm no computer
genius by any means, but the available docs were sufficient to help me along.
I sometimes do wonder though if I haven't done anything wrong, which is not
always apparent until it goes wrong.
As to the original question for a alternative, personally I tend to suspect
that his question is only partially about having an alternative but mostly
about venting some frustration (which I can understand, I've had it too at
times) and challenging the developers a bit. Nevertheless, I don't know of a
lot of alternatives and the reason might be that usually alternatives arise
when a lot of people need something and that they are not happy with what IS
available. Since a lot of people need clustering, my conclusion is that this
must simply be very adequate stuff.
