Hello All,<div><br></div><div>   I&#39;m wondering if anyone had expirence with RedHat&#39;s HA solution.  We&#39;re trying to setup a 2 node failover cluster for a Drupal install using multipath disks attached via HBAs.   It seems to work fine at the start, but after a while neither node can take ownership of the clustered volume group.  At this point, even trying to stop the clvmd service just hangs.  Any hints or pointers would be appreciated.  Below is the cluster.conf</div>
