[ale] RedHat HA Assistance

[Sam Davis]

Hello All,

   I'm wondering if anyone had expirence with RedHat's HA solution.  We'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


Thank you,
Sam Davis
