Re: [Xen-API] One resource pool and local lvm SR mirrored using DRBD

[George Shuklin <george.shuklin@xxxxxxxxx>]

Ok, DRBD actually consists of two parts: kernel modules (which one 
require proper gcc version and headers to build without glitches) and 
userspace tools, which one can be used without compilation (it can 
installed from rpm/repository by yum install drbd).
I am thinking it's much easier to install proper gcc and headers for xs 
dom0 kernel to vanilla centos than playing with specific 'ddk images'.
