The OS is RHEL 6.1 (64 bit) at our data center. We are having an identical setup at our DR site. We need to replicate the mail store and the mail queue to the DR site. For this we are planning to implement DRBD 8.4.3 (community version). We have created the DRBD related RPMs using the rpmbuild command and this has generated the following packages:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>drbd-heartbeat-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-xen-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-km-debuginfo-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-udev-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-pacemaker-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-debuginfo-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-utils-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-km-2.6.32_131.0.15.el6.x86_64-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal>drbd-bash-completion-8.4.3-2.el6.x86_64<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>We are finding that the packages drbd-heartbeat-8.4.3-2.el6.x86_64 and drbd-pacemaker-8.4.3-2.el6.x86_64 are “MUST TO INSTALL” for the installation of the package drbd-8.4.3-2.el6.x86_64. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Our question is whether these packages would interfere in any way with the Red Hat Cluster Suit.
