<br>
 Trying to adapt <a href="https://alteeve.ca/w/AN!Cluster_Tutorial_2" target="_blank">https://alteeve.ca/w/AN!Cluster_Tutorial_2</a> to EL7 +<br>
pacemaker will be no easy task at all. The concepts can port, but after<br>
that, you're pretty much on your own.<br>
<br>
 Out of curiosity, can you try pacemaker 1.1.12 on cman+corosync on<br>
EL6? I've avoided EL7 so far because it's still very very new, and a<br>
major departure from previous releases, so I am not convinced it's ideal<br>
for HA yet.<br>
<br>
 If you find that the RAID stuff works better on EL6, then it might be<br>
a sign of driver issues or something. Truth be told though, my early<br>
experiments with RAID and Supermicro didn't end well, so this might well<br>
be not OS related, too. Any firmware updates available?<br>
