Introduction
DRBD provides HA for block level devices, essentially allowing the possibility of a replicated SR across multiple XCP instances.
Install
Linbit provides a full install guide here: http://www.linbit.com/fileadmin/tech-guides/xenserver-drbd.pdf
The only modification needed for XCP is the RPMs to be installed need to be those created specifically for XCP, with further directions below.
Source Build
Install the build tools
sed -i -e "s/enabled=0/enabled=1/" /etc/yum.repos.d/CentOS-Base.repo sed -i -e "s/enabled=1/enabled=0/" /etc/yum.repos.d/Citrix.repo yum install gcc flex rpm-build redhat-rpm-config make libxslt
Install the kernel development package from the XCP 1.5 binary packages ISO
rpm -i kernel-xen-devel-2.6.32.12-0.7.1.xs1.4.90.530.170661.i686.rpm #might need to put this somewhere else and remote mount it via nfs wget http://downloads.xen.org/XCP/53341/sources/binpkg.iso mount -o loop binpkg.iso /mnt cd /mnt/domain0/RPMS/i686 rpm -i kernel-xen-devel-2.6.32.12-0.7.1.xs1.4.90.530.170661.i686.rpm
Download and build DRBD
