Chek if multicast is on in the ethernet switch on which the cluster
heartbeat is conencted

also try clustat command
how  about disabling selinux?
(ducking under the table) have you tried system-config-lvm gui tool
there is also a setting in lvm.conf which allows/disallows certain devices
that can/cannot appear as storage checkout the settings
