Hi,

The problem is that no distribution has a good recent verion of pacemaker 
included and you have to find out or to known which version of pacemaker really 
works good for what distribution. But this can change daily.
 
I prefer Debian Lenny for the moment and use 1.0.6 of pacemaker form madkiss 
repository. There is one bug in 1.0.6 you have to know about regarding the use 
of the GUI. Otherwise it is quite usable for simple setups.

But I hope that Madkiss' repository will soon be updated to the latest version 
1.0.8.

Also You have to know that a kernel update last Thursday broke Lennys DRBD 
module if you installed 8.0.14 from the usual repositories. I hope they fix it 
in the near future.

I had my problems with other distributions especially with opensuse 11.2. see 
my bug reports / postings to this list.

The main developement if done also on Fedora, so this should also be a good 
option.

You see: I have most experience in Debian. You have to find out yourself.

Start with SIMPLE resources, not with a DRBD/iSCSI-SAN setup.

Greetings,
